Safety recommendations
To avoid any equipment damage or bodily injury caused by incorrect use, read the following safety recommendations before installation. Note that the recommendations do not cover every possible hazardous condition.
· Before cleaning the switch, remove all power cords from the switch. Do not clean the switch with wet cloth or liquid.
· Do not place the switch near water or in a damp environment. Prevent water or moisture from entering the switch chassis.
· Do not place the switch on an unstable case or desk. The switch might be severely damaged in case of a fall.
· Ensure good ventilation of the equipment room and keep the air inlet and outlet vents of the switch free of obstruction.
· Connect the yellow-green protection grounding cable before power-on.
· Make sure the operating voltage is in the required range.
· To avoid electrical shocks, do not open the chassis while the switch is operating or when the switch is just powered off.
· When replacing FRUs, including power modules, fan trays, and expansion modules, wear an ESD wrist strap to avoid damaging the units.
Examining the installation site
The S6800 switches must be used indoors.
Mount your switch in a rack and verify the following items:
· Adequate clearance is reserved at the air inlet and outlet vents for ventilation.
· The rack has a good ventilation system.
· Identify the hot aisle and cold aisle at the installation site, and make sure ambient air flows into the switch from the cold aisle and exhausts to the hot aisle.
· Identify the airflow designs of neighboring devices, and prevent hot air flowing out of the bottom device from entering the top device.
· The rack is sturdy enough to support the switch and its accessories.
· The rack is reliably grounded.
To ensure correct operation and long service life of your switch, install it in an environment that meets the requirements. For more information about installation site requirements, see indoor installation requirements of H3C device operation.
Temperature/humidity
Maintain appropriate temperature and humidity in the equipment room.
· Lasting high relative humidity can cause poor insulation, electricity leakage, mechanical property change of materials, and metal corrosion.
· Lasting low relative humidity can cause washer contraction and ESD and cause problems including loose screws and circuit failure.
· High temperature can accelerate the aging of insulation materials and significantly lower the reliability and lifespan of the switch.
For the temperature and humidity requirements of different switch models, see H3C S6800 Switch Series Hardware Information and Specifications.
Cleanliness
Dust buildup on the chassis might cause electrostatic adsorption and dust corrosion, resulting in poor contact of metal connectors and contact points. This might shorten the device's lifetime and even cause device failure in the worst case. Table1-2 describes the switch requirement for cleanliness.
Table1-2 Switch requirement for cleanliness

≤ 1.8 × 107 particles/m3 |
To maintain cleanliness in the equipment room, follow these guidelines:
· Keep the equipment room away from pollution sources. Do not smoke, eat, or drink in the equipment room.
· Use double-layer glass in windows and seal doors and windows with dust-proof rubber strips. Use screen doors and window screens for doors and windows open to the outside and make sure the external windows are air tight.
· Use dustproof materials for floors, walls, and ceilings and use wallpaper or matt paint that does not produce powders.
· Clean the equipment room regularly and clean the air filters of the rack each month.
· Wear ESD clothing and shoe covers before entering the equipment room, keep the ESD clothing and shoe covers clean, and change them frequently.
Corrosive gas limit
Corrosive gases can accelerate corrosion and aging of metal components. Make sure the corrosive gases do not exceed the concentration limits as shown in Table1-3.

CAUTION: As a best practice, control the corrosive gas concentrations in the equipment room at their average values. Make sure the corrosive gas concentrations do not exceed 30 minutes per day at their maximum values. |
To control corrosive gases, use the following guidelines:
· As a best practice, do not build the equipment room in a place with a high concentration of corrosive gases.
· Make sure the equipment room is not connected to sewer, vertical shaft, or septic tank pipelines and keep it far away from these pipelines. The air inlet of the equipment room must be away from such pollution sources.
· Use environmentally friendly materials to decorate the equipment room. Avoid using organic materials that contains harmful gases, such as sulfur or chlorine-containing insulation cottons, rubber mats, sound-proof cottons, and avoid using plasterboards with high sulfur concentration.
· Place fuel (diesel or gasoline) engines separately. Do not place them in the same equipment room with the device. Make sure the exhausted air of the engines will not flow into the equipment room or towards the air inlet of the air conditioners.
· Place batteries separately. Do not place them in the same room with the device.
· Employ a professional company to monitor and control corrosive gases in the equipment room regularly.
EMI
All electromagnetic interference (EMI) sources, from outside or inside of the switch and application system, adversely affect the switch in the following ways:
· A conduction pattern of capacitance coupling.
· Inductance coupling.
· Electromagnetic wave radiation.
· Common impedance (including the grounding system) coupling.
To prevent EMI, use the following guidelines:
· If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE) to filter interference from the power grid.
· Keep the switch far away from radio transmitting stations, radar stations, and high-frequency devices.
· Use electromagnetic shielding, for example, shielded interface cables, when necessary.
· To prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning strikes, route interface cables only indoors.
Laser safety
|
|
WARNING! Disconnected optical fibers or transceiver modules might emit invisible laser light. Do not stare into beams or view directly with optical instruments when the switch is operating. |
The S6800 switches are Class 1 laser devices.
Installation tools
No installation tools are provided with the switch. Prepare the following tools yourself:
· Phillips screwdriver.
· ESD wrist strap.
· Marker.
2 Installing the switch

Attaching the mounting brackets and chassis rails to the chassis
The mounting bracket and chassis rail installation procedures are the same for the S6800-32Q, S6800-54QF, S6800-54QT, S6800-54HF, and S6800-54HT switches. For the S6800-54QF (LS-6800-54QF-H3), S6800-54QF (LS-6800-54QF-H5) and S6800-54QT (LS-6800-54QT-H3), four screws are required for install a mounting bracket at the port side. For the other models, three screws are required.
For an S6800-2C, S6800-2C-FC, or S6800-4C switch, use the four screw holes nearest to the port side and nearest to the power module side to install the mounting brackets at the port side and at the power module side, respectively.
To attach the mounting brackets and chassis rails to the chassis:
1. Align the mounting brackets with the screw holes in the chassis. Use M4 screws (provided) to attach the mounting brackets to the chassis.
¡ To install the mounting brackets at the power module side, see Figure2-16, Figure2-17, and Figure2-18.
¡ To install the mounting brackets at the port side, see Figure2-19, Figure2-20, Figure2-21, Figure2-22, Figure2-23, Figure2-24, and Figure2-25.
2. Align the chassis rails with the rail mounting holes in the chassis:
¡ If the mounting brackets are in the power module-side mounting position, align the chassis rails with the screw holes at the front of the side panels (see Figure2-16, Figure2-17, and Figure2-18).
¡ If the mounting brackets are in the port-side mounting position, align the chassis rails with the screw holes at the rear of the side panels (see Figure2-19, Figure2-20, Figure2-21, Figure2-22, Figure2-23, Figure2-24, and Figure2-25).
3. Use M4 screws (provided) to attach the chassis rails to the chassis. As a best practice, use a torque of 12 kgf-cm (1.18 Nm) to fasten the M4 screws.
Secure the mounting brackets and chassis rails to both sides of the chassis in the same way.
To use super-short slide rails for the S6800-54QF (LS-6800-54QF-H3 and LS-6800-54QF-H5), you can install the chassis rails through narrow-spacing or wide-spacing installation, depending on the distance between the front and rear rack posts, as shown in Figure2-21 and Figure2-22.

Connecting the grounding cable to the chassis
|
|
CAUTION: · If the grounding cable length or terminal type cannot meet your requirement, make an applicable grounding cable or contact H3C Support. · If you use a grounding point on the side panel, connect the grounding cable to the grounding point before you mount the switch in the rack. |
The S6800-54QF (LS-6800-54QF-H3 and LS-6800-54QF-H5), S6800-54QT (LS-6800-54QT-H3), S6800-54HF, S6800-54HT, S6800-2C, and S6800-2C-FC switches each provide two grounding points on the left side panel: primary grounding point and auxiliary grounding point 1. Use M5 grounding screws to attach the grounding cable that has a single-hole grounding lug or two-hole grounding lug to the switch. Choose the grounding point according to the mounting bracket installation positions. If you install the mounting brackets at the port side, use the grounding point near the ports. If you install the mounting brackets at the power module side, use the grounding point near the power modules.
The S6800-32Q, S6800-54QF (LS-6800-54QF and LS-6800-54QF-H1), S6800-54QT (LS-6800-54QT and LS-6800-54QT-H1), and S6800-4C switches each provide three grounding points. The primary grounding point and auxiliary grounding point 1 are on the side panel, and auxiliary grounding point 2 is on the rear panel. If you use a grounding cable that has a two-hole grounding lug, connect it to the primary grounding point or auxiliary grounding point 1. If you use a grounding cable that has a single-hole grounding lug, connect it to auxiliary grounding point 2. Use M5 grounding screws to attach the grounding cable to the switch. Choose the grounding point according to the mounting bracket installation positions.
This section uses the primary grounding point on the S6800-54QF (LS-6800-54QF-H3) switch as an example.
To connect the grounding cable to a grounding point:
1. Unpack the grounding cable and grounding screws.
2. Align the single-hole grounding lug or two-hole grounding lug at one end of the cable with the grounding holes of the grounding point, insert the grounding screws into the holes, and tighten the screws with a screwdriver, as shown in Figure2-26 and Figure2-27. As a best practice, use a torque of 30 kgf-cm (2.94 Nm) to fasten the screws.
Attaching the slide rails to the rack
The procedures are the same for attaching 1U and 2U slide rails to the rack. This section uses the 1U slide rails as an example.
To attach the slide rails to the rack:
1. Identify the planned slide rail installation position in the rack.
Plan a 1U rack space for installation of 1U slide rails and a 2U rack space for installation of 2U slide rails. Figure2-28 shows a standard 1U rack space.
In a standard 1U rack space, there are three installation holes, one in the middle for auxiliary installation and one at either end for standard installation. The spacing between two adjacent standard installation holes is slightly smaller than the distance between a standard installation hole and the middle, auxiliary installation hole.
Figure2-28 1U rack space
2. Install cage nuts (user-supplied) in the mounting holes in the rack posts.
3. Align the screw holes in one slide rail with the cage nuts in the rack post on one side, and use M6 screws (user-supplied) to attach the slide rail to the rack, as shown in Figure2-29. As a best practice, use a torque of 30 kgf-cm (2.94 Nm) to fasten the M6 screws.
4. Repeat the preceding steps to attach the other slide rail to the rack post on the other side.
Keep the two slide rails at the same height so the slide rails can attach into the chassis rails.
Figure2-29 Installing the 1U slide rails
Mounting the switch in the rack
This task requires two people.
To mount the switch in the rack:
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2. Verify that the mounting brackets and chassis rails have been securely attached to the switch chassis.
3. Verify that the slide rails have been correctly attached to the rear rack posts.
4. Install cage nuts (user-supplied) to the front rack posts and make sure they are at the same level as the slide rails.
5. One person performs the following operations:
a. Supporting the bottom of the switch, aligns the chassis rails with the slide rails on the rack posts.
b. Pushes the switch slowly to slide the chassis rails along the slide rails until the mounting brackets are flush with the rack posts.
6. The other person uses M6 screws (user-supplied) to attach the mounting brackets to the rack. As a best practice, use a torque of 30 kgf-cm (2.94 Nm) to fasten the M6 screws.
If the slide rails or long slide rails are used, make sure the front ends of the slide rails or long slide rails reach out of the chassis rails. If the super-short slide rails are used, make sure the super-short slide rails slide a minimum length of 90 mm (3.54 in) into the chassis rails.
The rack-mounting procedures are the same for the S6800-32Q, S6800-54QF, S6800-54QT, S6800-54HF, S6800-54HT, S6800-2C-FC, and S6800-2C switches. The following figures use the S6800-2C switch as an example.
Figure2-31 Mounting the S6800-2C switch in the rack (port-side mounting position for the mounting brackets)
|
|
NOTE: To rack-mount the S6800-4C switch by using 2U high mounting brackets and slide rails, use two screws and two cage nuts to attach each mounting bracket to the rack. Determine the screw installation positions based on the distances between the square holes on the rack posts. The screw installation positions in Figure2-32 and Figure2-33 are for illustration only. |
Grounding the switch by using a grounding strip
|
|
CAUTION: · Correctly connecting the grounding cable is crucial to lightning protection and EMI protection. · Do not connect the grounding cable to a fire main or lightning rod. · To guarantee the grounding effect and avoid switch damage, use the grounding cable provided with the switch to connect the switch to a grounding strip in the equipment room. |
The power input end of the switch has a noise filter, whose central ground is directly connected to the chassis to form the chassis ground (commonly known as PGND). You must securely connect this chassis ground to the earth so the faradism and leakage electricity can be safely released to the earth to minimize EMI susceptibility of the switch.
To ground the switch by using a grounding strip:
1. Select a grounding point on the switch as required.
2. Attach the single-hole grounding lug at one end of the grounding cable to the grounding point on the switch chassis. For more information, see "Connecting the grounding cable to the chassis."
3. Remove the hex nut of a grounding post on the grounding strip.
4. Attach the ring terminal at the other end of the grounding cable to the grounding post on the grounding strip, and secure the ring terminal to the grounding post with the hex nut.

Installing and removing a fan tray
Follow these guidelines when you install or remove a fan tray:
· You must install fan trays of the same model on the switch.
· An S6800-54QT (LS-6800-54QT-H3) switch supports 4+1 fan tray redundancy. The switch can operate correctly with four fan trays. In the remaining fan tray slot, you can install a fan tray for 4+1 redundancy or a filler panel. On the other switch models, you must install a fan tray in each fan tray slot.
· Make sure all slots have a module or filler panel installed when the switch is operating.
· For an S6800-32Q, S6800-2C, or S6800-2C-FC switch, if both fan trays fail during the switch operation, replace the fan trays within two minutes one by one.
· For an S6800-4C, S6800-54QF (LS-6800-54QF), S6800-54QF (LS-6800-54QF-H1), S6800-54QT (LS-6800-54QT), S6800-54QT (LS-6800-54QT-H1), S6800-54HF, or S6800-54HT switch, if both fan trays fail during the switch operation, replace the fan trays within one minute.
· For an S6800-54QF (LS-6800-54QF-H3), S6800-54QF (LS-6800-54QF-H5), or S6800-54QT (LS-6800-54QT-H3) switch, if more than one fan tray fail during the switch operation, replace the faulty fan trays one by one and finish replacing a fan tray within three minutes.

Setting terminal parameters
To configure and manage the switch through the console port, you must run a terminal emulator program, HyperTerminal or PuTTY, on your configuration terminal. You can use the emulator program to connect a network device, a Telnet site, or an SSH site. For more information about the terminal emulator programs, see the user guides for these programs
The following are the required terminal settings:
· Bits per second—9600.
· Data bits—8.
· Stop bits—1.
· Parity—None.
· Flow control—None.
Powering on the switch
Before powering on the switch, verify that the following conditions are met:
· The power cord is correctly connected.
· The input power voltage meets the requirement of the switch.
· The console cable is correctly connected.
· The configuration terminal (a PC, for example) has started, and its serial port settings are consistent with the console port settings on the switch.
Power on the switch. During the startup process, you can access Boot ROM menus to perform tasks such as software upgrade and file management. The Boot ROM interface and menu options differ with software versions. For more information about Boot ROM menu options, see the software-matching release notes for the device.
After the startup completes, you can access the CLI to configure the switch.
For more information about the configuration commands and CLI, see H3C S6800 Switch Series Configuration Guides and H3C S6800 Switch Series Command References.
4 Setting up an IRF fabric
You can use H3C IRF technology to connect and virtualize S6800 switches into a large virtual switch called an "IRF fabric" for flattened network topology, and high availability, scalability, and manageability.
The S6800 switches are divided into the following groups. Only members in the same group can form an IRF fabric.
· S6800-54HF, S6800-54HT, S6800-2C-FC, S6800-32Q (LS-6800-32Q-H1), S6800-54QF (LS-6800-54QF-H1, LS-6800-54QF-H3 and LS-6800-54QF-H5), S6800-54QT (LS-6800-54QT-H1 and LS-6800-54QT-H3), S6800-2C (LS-6800-2C-H1), and S6800-4C (LS-6800-4C-H1).
· S6800-32Q (LS-6800-32Q), S6800-2C (LS-6800-2C), S6800-4C (LS-6800-4C), S6800-54QF (LS-6800-54QF), and S6800-54QT (LS-6800-54QT).
To set up IRF links between two switches, use the 10-GE, 40-GE, or 100-GE ports.

6. Connect the physical IRF ports. |
Connect the physical IRF ports on switches. Use SFP+, QSFP+, or QSFP28 transceiver modules and fibers for long-distance connection. Use twisted pair cables or SFP+, QSFP+, or QSFP28 cables for short-distance connection. All switches except the master switch automatically reboot, and the IRF fabric is established. |
Planning IRF fabric setup
This section describes issues that an IRF fabric setup plan must cover.
Planning IRF fabric size and the installation site
Choose switch models and identify the number of required IRF member switches, depending on the user density and upstream bandwidth requirements. The switching capacity of an IRF fabric equals the total switching capacities of all member switches.
Plan the installation site depending on your network solution as follows:
· Place all IRF member switches in one rack for centralized high-density access.
· Distribute the IRF member switches in different racks to implement the top-of-rack (ToR) access solution for a data center.
As your business grows, you can plug H3C S6800 switches into the IRF fabric to increase the switching capacity without any topology change or replacement.
Identifying the master switch and planning IRF member IDs
Determine which switch you want to use as the master for managing all member switches in the IRF fabric. An IRF fabric has only one master switch. You configure and manage all member switches in the IRF fabric at the command line interface of the master switch.
|
|
NOTE: IRF member switches will automatically elect a master. You can affect the election result by assigning a high member priority to the intended master switch. For more information about master election, see H3C S6800 Switch Series IRF Configuration Guide or H3C S6800 Switch Series Virtual Technologies Configuration Guide, depending on the software version. |
Prepare an IRF member ID assignment scheme. An IRF fabric uses member IDs to uniquely identify and manage its members, and you must assign each IRF member switch a unique member ID.
Planning IRF topology and connections
You can create an IRF fabric in daisy chain topology, or more reliably, ring topology. In ring topology, the failure of one IRF link does not cause the IRF fabric to split as in daisy chain topology. Rather, the IRF fabric changes to a daisy chain topology without interrupting network services.
You connect the IRF member switches through IRF ports, the logical interfaces for the connections between IRF member switches. Each IRF member switch has two IRF ports: IRF-port 1 and IRF-port 2. To use an IRF port, you must bind at least one physical port to it.
When connecting two neighboring IRF member switches, you must connect the physical ports of IRF-port 1 on one switch to the physical ports of IRF-port 2 on the other switch.
The IRF port connections in the two figures are for illustration only, and more connection methods are available.
Figure4-2 IRF fabric in daisy chain topology
Figure4-3 IRF fabric in ring topology
You can provide the following IRF physical connections between S6800 switches:
· 10-GE IRF physical connection by connecting 10GBase-T Ethernet ports or SFP+ ports.
· 40-GE IRF physical connection by connecting QSFP+ ports.
· 100-GE or 40-GE IRF physical connection by connecting QSFP28 ports.
· IRF physical connection by using a 40G QSFP+ to 4 × 10G SFP+ cable to connect a QSFP+ port and four SFP+ ports.
You can bind several ports to an IRF port for increased bandwidth and availability.
Identifying physical IRF ports on the member switches
Identify the 10GBase-T Ethernet ports, SFP+ ports, QSFP+, and QSFP28 ports to be used for IRF connections on the member switches according to your topology and connection scheme.
All the 10GBase-T Ethernet ports, SFP+ ports, QSFP+ ports, and QSFP28 ports on the S6800 switch can be used for IRF connections.
When you use QSFP+ cables to connect physical IRF ports, follow these guidelines:
· Make sure the two ports on an IRF link are both fixed ports or ports on interface modules.
· If you use ports on interface modules as physical IRF ports, make sure the interface modules on an IRF link are the same model.
Planning the cabling scheme
You can use twisted pair cables, SFP+/QSFP+/QSFP28 cables, or SFP+/QSFP+/QSFP28 transceiver modules and optical fibers to connect the switches for IRF connections. If the IRF member switches are far away from one another, choose the SFP+/QSFP+/QSFP28 transceiver modules and optical fibers. If the IRF member switches are all in one equipment room, choose twisted pair cables or SFP+/QSFP/QSFP28 cables. For more information about available transceiver modules and cables, see H3C S6800 Switch Series Hardware Information and Specifications.
The following subsections describe several H3C recommended IRF connection schemes, and all these schemes use a ring topology.
Connecting the IRF member switches in one rack
Figure4-4 shows an example for connecting four IRF member switches in a rack by using QSFP+ cables and QSFP+ transceiver modules and optical fibers. The switches in the ring topology (see Figure4-5) are in the same order as connected in the rack.
Figure4-4 Connecting the switches in one rack
Connecting the IRF member switches in a ToR solution
You can install IRF member switches in different racks side by side to deploy a top of rack (ToR) solution.
Figure4-6 shows an example for connecting four top of rack IRF member switches by using QSFP+ cables and QSFP+ transceiver modules and optical fibers. The topology is the same as Figure4-5.
Configuring basic IRF settings
After you install the IRF member switches, power on the switches, and log in to each IRF member switch (see H3C S6800 Switch Series Fundamentals Configuration Guide) to configure their member IDs, member priorities, and IRF port bindings.
Follow these guidelines when you configure the switches:
· Assign the master switch higher member priority than any other switch.
· Bind physical ports to IRF port 1 on one switch and to IRF port 2 on the other switch. You perform IRF port binding before or after connecting IRF physical ports depending on the software release.
· Execute the display irf configuration command to verify the basic IRF settings.
For more information about configuring basic IRF settings, see H3C S6800 Switch Series IRF Configuration Guide or H3C S6800 Switch Series Virtual Technologies Configuration Guide, depending on the software version.
Connecting the physical IRF ports

|
CAUTION: Wear an ESD wrist strap when you connect cables or transceiver modules and optical fibers. For more information, see the installation guide for the transceiver modules. |
Use cables or transceiver modules and optical fibers to connect the IRF member switches as planned.
Accessing the IRF fabric to verify the configuration
To verify the basic functionality of the IRF fabric after you finish configuring basic IRF settings and connecting IRF ports:
1. Log in to the IRF fabric through the console port of any member switch.
2. Create a Layer 3 interface, assign it an IP address, and make sure the IRF fabric and the remote network management station can reach each other.
3. Use Telnet or SNMP to access the IRF fabric from the network management station. (See H3C S6800 Switch Series Fundamentals Configuration Guide.)
4. Verify that you can manage all member switches as if they were one node.
5. Display the running status of the IRF fabric by using the commands in Table4-1.

NOTE: To avoid IP address collision and network problems, configure at least one multi-active detection (MAD) mechanism to detect the presence of multiple identical IRF fabrics and handle collisions. For more information about MAD detection, see H3C S6800 Switch Series IRF Configuration Guide or H3C S6800 Switch Series Virtual Technologies Configuration Guide, depending on the software version. |
5 Setting up an M-LAG system
Multichassis Link Aggregation (M-LAG) virtualizes two physical devices into one system through multichassis link aggregation to provide device-class high availability and load sharing.
Compared to IRF, M-LAG offers higher network reliability and shorter service interruption during upgrade.
You cannot configure IRF and M-LAG on the same network.
|
|
IMPORTANT: · In Release 2702 and earlier, M-LAG is called DRNI and uses the DRNI set of command keywords in the CLI. · In Release 6710 and later, the device supports both the M-LAG set and DRNI set of command keywords in the CLI by default. The two sets of commands are consistent in the service configuration methods, functions, and output, with only differences in the command keywords. For the differences in the command keywords, see M-LAG configuration in H3C S6800 & S6860 Switch Series Layer 2—LAN Switching Configuration Guide. |

Planning for setting up an M-LAG system
Determining device installation locations
An M-LAG system can be set up with only two devices. Reserve sufficient space in the rack for installation of the devices.
You can place the two switches in one cabinet. Alternatively, you can install the switches in two cabinets if you're seeking a top-of-rack access solution in the data center.
Reserving physical ports for M-LAG connection
To set up an M-LAG system, you must establish a peer link and a keepalive link between the two devices.
The M-LAG member devices exchange protocol packets and transmit data traffic over the peer link. An M-LAG system has only one peer link. You can create a peer-link interface on each M-LAG member device, and the link between the two peer-link interfaces is the peer link.
The M-LAG member devices exchange keepalive packets over the keepalive link to detect multi-active collisions when the peer link is down.
Peer link
In addition to protocol packets, the peer link also transmits data packets between the M-LAG member devices when an uplink fails. When you set up the peer link, follow these restrictions and guidelines:
· Configure the peer-link aggregation group as follows:
¡ If an M-LAG member device is a fixed-port device with interface expansion modules, assign ports from multiple interface expansion modules to the aggregation group for the peer-link interface. Make sure at least one member port resides on a different slot than the uplink interfaces.
¡ If an M-LAG member device is a fixed-port device, assign at least two physical interfaces to the aggregation group for the peer-link interface.
· The member ports in the aggregation group for the peer-link interface must have the same speed.
· If an M-LAG system is attached to a large number of servers by using non-M-LAG interfaces, take the size of the traffic sent among those servers into account when you determine the bandwidth of the peer link.
Keepalive link
As a best practice, establish a dedicated direct link between two M-LAG member devices as a keepalive link. Do not use the keepalive link for any other purposes. Make sure the M-LAG member devices have Layer 2 and Layer 3 connectivity to each other over the keepalive link.
You can use management Ethernet interfaces, Layer 3 Ethernet interfaces, Layer 3 aggregate interfaces, or interfaces with a VPN instance bound to set up the keepalive link.
As a best practice, do not use VLAN interfaces for keepalive link setup. If you have to use VLAN interfaces, remove the peer-link interfaces from the related VLANs to avoid loops.
On a device with interface expansion modules, do not use the same module to provide interfaces for setting up the keepalive link and peer link.
Planning the cable connection scheme
Select cables or transceiver modules and optical fibers matching the rate of physical ports of the peer link and the keepalive link for connection.
Cables are short but with high performance and stability, suitable for short-distance connections in the equipment room. Transceiver modules and optical fibers can be combined flexibly and is suitable for longer distance connections.
For information about the transceiver modules and cables supported by the switch, see H3C S6800 Switch Series Hardware Information and Specifications.
This following section describes several cable connection schemes that use 40G physical ports for the peer link connection and the keepalive link connection, with matching cables or transceiver module and optical fibers.
|
|
NOTE: The physical port locations in the following figures are for illustration only. |
Connecting the member switches in one rack
If two M-LAG member devices are installed in the same rack, use the following connection method to connect them as a best practice.
Figure5-2 Connecting two M-LAG member devices are installed in the same rack
Figure5-3 Connection topology of two M-LAG member devices in the same rack
Top of rack connection scheme
You can install M-LAG member switches in two different racks side by side to deploy a top of rack (ToR) solution as shown in Figure5-4. Use transceiver modules and optical fibers for connection if a large distance exists between the member switches.
Figure5-4 Top of rack connection scheme
Configuring the M-LAG system settings
After you install the M-LAG member switches, start and log in to each member switch to configure basic M-LAG system settings, including:
· M-LAG system MAC address.
· M-LAG system ID.
· M-LAG system priority.
· Peer-link interface settings.
· Keepalive parameters.
For information about logging in to the switch, see H3C S6800 & S6860 Switch Series Fundamentals Configuration Guide.
For information about configuring the M-LAG system settings, see M-LAG configuration in H3C S6800 Ethernet Switch Series Layer 2—LAN Switching Configuration Guide.
Restrictions and guidelines
You can set up an M-LAG system with only two member devices. For the M-LAG member devices to be identified as a single M-LAG system, you must configure the same M-LAG system MAC address and M-LAG system priority for them. To distinguish between the two member devices, assign them different M-LAG system IDs.
Make sure the MAC address of the M-LAG system is unique.
For correct packet forwarding, delete M-LAG configuration from an M-LAG member device if it leaves its M-LAG system.
When you bulk shut down physical interfaces on an M-LAG member device for service changes or hardware replacement, shut down the physical interfaces used for keepalive detection prior to the physical member ports of the peer-link interface. If you fail to do so, link flapping will occur on the member ports of M-LAG interfaces.
You must configure the keepalive link interfaces (including physical ports and logical interfaces) as M-LAG reserved interfaces. This ensures that these interfaces will not be MAD down when the peer link fails.
For more configuration restrictions and guidelines and typical configuration examples for the M-LAG system, see H3C Data Center Switches M-LAG Configuration Guide.
Connecting the M-LAG member switches
|
|
CAUTION: Wear an ESD wrist strap when you connect the M-LAG member switches. Make sure the strap makes good skin contact and is reliably grounded. |
Connect the M-LAG member switches based on the network topology and cable connection scheme. For the installation method and restrictions and guidelines for connecting cables or transceiver modules and optical fibers, see the installation guide for them.
Verifying the configuration
To verify the running status of the M-LAG system:
1. Create a Layer 3 interface on a member device, assign it an IP address, and make sure the device and the remote network management station can reach each other.
2. Use Telnet or SNMP to access the device remotely. For more information, see H3C S6800 & S6860 Switch Series Fundamentals Configuration Guide.
3. Display the running status of the M-LAG system by using the display commands in any view.

For more information, see H3C Data Center Switches M-LAG Configuration Guide. |
6 Maintenance and troubleshooting
Power module failure
You can use the LEDs on the power module to identify a power module failure. For more information about the LEDs on a power module, see H3C S6800 Switch Series Hardware Information and Specifications.
The LEDs on the power module are steady green (active) or flashing green (standby) while the power module system is correctly operating. If the LEDs behave in any other way, verify the following items:
· The switch power cord is correctly connected.
· The power source meets the requirement.
· The operating temperature of the switch is in the normal range and the power module has good ventilation.
If the issue persists, contact the H3C technical support for help.
To replace a power module, see "Installing and removing a power module."
Fan tray failure
When an LSWM1FANSC, LSWM1FANSCB, LSWM1HFANSC, or LSWM1HFANSCB fan tray is faulty, the system status LED on the switch is steady red and the system outputs alarm messages.
When an LSWM1BFANSC, LSWM1BFANSC-SN, LSWM1BFANSCB, or LSWM1BFANSCB-SN fan tray is faulty, the Alarm LED on the fan tray is steady yellow and the system outputs alarm messages.
When an LSPM1FANSA, LSPM1FANSA-SN, LSPM1FANSB, or LSPM1FANSB-SN fan tray is faulty, the fan tray LED is steady yellow and the system outputs alarm messages.
To replace a failed fan tray, see "Installing and removing a fan tray."
Follow these guidelines when you install or remove a fan tray:
· For an S6800-32Q, S6800-2C, or S6800-2C-FC switch, if both fan trays fail during the switch operation, replace the fan trays within two minutes.
· For an S6800-4C, S6800-54QF (LS-6800-54QF or LS-6800-54QF-H1), S6800-54QT (LS-6800-54QT or LS-6800-54QT-H1), S6800-54HF, or S6800-54HT switch, if both fan trays fail during the switch operation, replace the fan trays within one minute.
· For an S6800-54QF (LS-6800-54QF-H3 or LS-6800-54QF-H5) or S6800-54QT (LS-6800-54QT-H3) switch, if more than one fan tray fail during the switch operation, replace the faulty fan trays one by one and finish replacing a fan tray within three minutes.
