VLAN ID

Modulo

Modulo Value

The device automatically maps 4094 VLANs to the corresponding MSTIs based on the modulo value.

Enable STP Globally

Select whether to enable STP globally.

Other MSTP configurations take effect only after you enable STP globally.

BPDU Guard

Select whether to enable BPDU guard

BPDU guard can protect the device from malicious BPDU attacks, making the network topology stable.

Mode

Set the working mode of STP, which can be STP, RSTP, or MSTP.

·     STP: Each port on a device sends out STP BPDUs.

·     RSTP: Each port on a device sends out RSTP BPDUs, and automatically migrates to STP-compatible mode when detecting that it is connected with a device running STP.

·     MSTP: Each port on a device sends out MSTP BPDUs, and automatically migrates to STP-compatible mode when detecting that it is connected with a device running STP.

Max Hops

Set the maximum number of hops in an MST region to restrict the region size.

The setting can take effect only when it is configured on the regional root bridge.

Path Cost Standard

Specify the standard for path cost calculation. It can be Legacy, IEEE 802.1D-1998, or IEEE 802.1T.

Bridge Diameter

Any two stations in a switched network are interconnected through a specific path composed of a series of devices. The bridge diameter (or the network diameter) is the number of devices on the path composed of the most devices.

After you set the network diameter, you cannot set the timers. Instead, the device automatically calculates the forward delay, hello time, and max age.

 IMPORTANT:

·     The configured network diameter is effective for CIST only, not for MSTIs.

·     The bridge diameter cannot be configured together with the timers.

Timers

Forward Delay

Set the delay for the root and designated ports to transit to the forwarding state.

 IMPORTANT:

·     The settings of hello time, forward delay and max age must meet a certain formula. Otherwise, the network topology will not be stable. H3C recommends you to set the network diameter and then have the device automatically calculate the forward delay, hello time, and max age.

·     The bridge diameter cannot be configured together with the timers.

Hello Time

Set the interval at which the device sends hello packets to the surrounding devices to make sure that the paths are fault-free.

Max Age

Set the maximum length of time a configuration BPDU can be held by the device.

Instance

Instance ID

Set the role of the device in the MSTI or the bridge priority of the device, which is one of the factors deciding whether the device can be elected as the root bridge.

Role of the device in the MSTI:

·     Not Set: Not set (you can set the bridge priority of the device when selecting this role)

·     Primary: Configure the device as the root bridge (you cannot set the bridge priority of the device when selecting this role)

·     Secondary: Configure the device as a secondary root bridge (you cannot set the bridge priority of the device when selecting this role).

Root Type

Bridge Priority

tc-protection

Select whether to enable TC-BPDU guard.

When receiving topology change (TC) BPDUs, the device flushes its forwarding address entries. If someone forges TC-BPDUs to attack the device, the device will receive a large number of TC-BPDUs within a short time and frequently flushes its forwarding address entries. This affects network stability.

With the TC-BPDU guard function, you can prevent frequent flushing of forwarding address entries.

 IMPORTANT:

H3C does not recommend you to disable this function.

tc-protection threshold

Set the maximum number of immediate forwarding address entry flushes the device can perform within a certain period of time after receiving the first TC-BPDU.

STP

Select whether to enable STP on the port.

Protection

Set the type of protection to be enabled on the port:

·     Not Set: No protection is enabled on the port.

·     Edged Port, Root Protection, Loop Protection: For more information, see Table 15.

Instance

Instance ID

Set the priority and path cost of the port in the current MSTI.

·     The priority of a port is an important factor in determining whether the port can be elected as the root port of a device. If all other conditions are the same, the port with the highest priority will be elected as the root port. On an MSTP-enabled device, a port can have different priorities in different MSTIs, and the same port can play different roles in different MSTIs, so that data of different VLANs can be propagated along different physical paths, implementing per-VLAN load balancing. You can set port priority values based on the actual networking requirements.

·     Path cost is a parameter related to the rate of a port. On an MSTP-enabled device, a port can have different path costs in different MSTIs. Setting appropriate path costs allows VLAN traffic flows to be forwarded along different physical links, achieving VLAN-based load balancing. The device can automatically calculate the default path cost; alternatively, you can also manually configure path cost for ports.

Port Priority

Auto Path Cost

Manual Path Cost

Advanced

Point to Point

Specify whether the port is connected to a point-to-point link.

·     Auto: Automatically detects whether the link type of the port is point-to-point.

·     Force False: Specifies that the link type for the port is not point-to-point link.

·     Force True: Specifies that the link type for the port is point-to-point link.

 IMPORTANT:

If a port is configured as connecting to a point-to-point link, the setting takes effect for the port in all MSTIs. If the physical link to which the port connects is not a point-to-point link and you force it to be a point-to-point link by configuration, the configuration may incur a temporary loop.

Transmit Limit

Configure the maximum number of MSTP packets that can be sent during each Hello interval.

The larger the transmit limit is, the more network resources will be occupied. H3C recommends that you use the default value.

MSTP Mode

Set whether the port migrates to the MSTP mode.

In a switched network, if a port on an MSTP (or RSTP) device connects to a device running STP, this port will automatically migrate to the STP-compatible mode. After the device running STP is removed, the port on the MSTP (or RSTP) device may not be able to migrate automatically to the MSTP (or RSTP) mode, but will remain working in the STP-compatible mode. You can set this option to enable the port to automatically migrate to the MSTP (or RSTP) mode.

Select port(s)

Select one or multiple ports on which you want to configure MSTP on the chassis front panel. If aggregate interfaces are configured on the device, the page displays a list of aggregate interfaces below the chassis front panel. You can select aggregate interfaces from this list.

Edged Port

Set the port as an edge port.

Some ports of access layer devices are directly connected to PCs or file servers, which cannot generate BPDUs. You can set these ports as edge ports to achieve fast transition for these ports.

H3C recommends that you enable the BPDU guard function in conjunction with the edged port function to avoid network topology changes when the edge ports receive configuration BPDUs.

Root Protection

Enable the root guard function.

Configuration errors or attacks may result in configuration BPDUs with their priorities higher than that of a root bridge, which causes a new root bridge to be elected and network topology change to occur. The root guard function is used to address such a problem.

Loop Protection

Enable the loop guard function.

By keeping receiving BPDUs from the upstream device, a device can maintain the state of the root port and other blocked ports. These BPDUs may get lost because of network congestion or unidirectional link failures. The device will re-elect a root port, and blocked ports may transit to the forwarding state, causing loops in the network. The loop guard function is used to address such a problem.

[FORWARDING]

The port is in forwarding state: The port learns MAC addresses and forwards user traffic.

[LEARNING]

The port is in learning state: The port learns MAC addresses but does not forward user traffic.

[DISCARDING]

The port is in discarding state: The port does not learn MAC addresses or forward user traffic.

[DOWN]

The port is down.

Network Device Address

LLDP Enable

Select from the list to enable or disable global LLDP.

CDP Compatibility

Select from the list to enable or disable CDP compatibility of LLDP.

 IMPORTANT:

·     To enable LLDP to be compatible with CDP on a port, you must set the CDP work mode (or the CDP operating mode) on the port to TxRx in addition to enabling CDP compatibility on the Global Setup tab.

·     As the maximum TTL allowed by CDP is 255 seconds, you must make sure that the product of the TTL multiplier and the LLDPDU transmit interval is less than 255 seconds for CDP-compatible LLDP to work properly with Cisco IP phones.

Fast LLDPDU Count

Set the number of LLDPDUs sent each time fast LLDPDU transmission is triggered.

TTL Multiplier

Set the TTL multiplier.

The TTL TLV carried in an LLDPDU determines how long the device information carried in the LLDPDU can be saved on a recipient device. You can configure the TTL of locally sent LLDPDUs to determine how long information about the local device can be saved on a neighbor device by setting the TTL multiplier. The TTL is expressed as TTL multiplier × LLDPDU transit interval.

 IMPORTANT:

·     If the product of the TTL multiplier and the LLDPDU transmit interval is greater than 65535, the TTL carried in transmitted LLDPDUs takes 65535 seconds.

·     As the maximum TTL allowed by CDP is 255 seconds, you must make sure that the product of the TTL multiplier and the LLDPDU transmit interval is less than 255 seconds for CDP-compatible LLDP to work properly with Cisco IP phones.

Trap Interval

Set the minimum interval for sending traps.

With the LLDP trapping function enabled on a port, traps are sent out the port to advertise the topology changes detected over the trap interval to neighbors. By tuning this interval, you can prevent excessive traps from being sent when topology is instable.

Reinit Delay

Set initialization delay for LLDP-enabled ports.

Each time the LLDP operating mode of a port changes, its LLDP protocol state machine re-initializes. To prevent LLDP from being initialized too frequently at times of frequent operating mode change, initialization delay is introduced. With this delay mechanism, a port must wait for the specified interval before it can initialize LLDP after the LLDP operating mode changes.

Tx Delay

Set LLDPDU transmit delay.

With LLDP enabled, a port advertises LLDPDUs to its neighbors both periodically and when the local configuration changes. To avoid excessive number of LLDPDUs caused by frequent local configuration changes, an LLDPDU transmit delay is introduced. After sending an LLDPDU, the port must wait for the specified interval before it can send another one.

 IMPORTANT:

LLDPDU transmit delay must be less than the TTL to make sure that the LLDP neighbors can receive LLDPDUs to update information about the device you are configuring before it is aged out.

Tx Interval

Set the LLDPDU transmit interval.

 IMPORTANT:

If the product of the TTL multiplier and the LLDPDU transmit interval is greater than 65535, the TTL carried in transmitted LLDPDUs takes 65535 seconds. The likelihood exists that the LLDPDU transmit interval is greater than TTL. You should avoid the situation, because the LLDP neighbors will fail to receive LLDPDUs to update information about the device you are configuring before it is aged out.
