1.1.2 ndp enable

Syntax

ndp enable [ interface interface-list ]

undo ndp enable [ interface interface-list ]

View

System view, Ethernet interface view

Parameter

interface interface-list: Specifies a list of ports. The list can contain consecutive or separated ports, or the combination of the both. You need to provide the interface-list argument in the form of interface-type interface-number [ to interface-type interface-number ] &<1-10>, where interface-type specifies the port type, and interface-number specifies the port number (in the form of slot number/port number).to: Specifies a port range. &<1-10> means that you can provide up to ten port indexes/port index ranges for this argument.

Description

Use the ndp enable command to enable NDP globally or on a port.

Use the undo ndp enable command to disable NDP globally or on a port.

By default, NDP is enabled both globally and on an Ethernet port.

Note that:

l The NDP cannot operate if it is enabled on a port where NDP is disabled.

l When being executed in system view, the ndp enable command enables NDP globally if you do not provide the interface interface-list argument. And if you specify the interface interface-list argument, the command enables NDP for the specified Ethernet port(s).

l When being executed in Ethernet interface view, this command enables NDP for the current Ethernet port only. In this case, the interface-list argument is not needed.

l When a port of an aggregation group is connected with a device in a cluster, the NDP feature must be enabled on all the ports of the aggregation group before the feature can work properly.

Example

# Enable NDP globally.

<Sysname> system-view

[Sysname] ndp enable

1.1.3 ndp timer aging

Syntax

ndp timer aging aging-time

undo ndp timer aging

View

System view

Parameter

aging-time : Holdtime (in seconds) to be set of the NDP information sent by the local switch. This argument ranges from 5 to 255.

Description

Use the ndp timer aging command to set the holdtime of the NDP information sent by the local switch, that is, to specify how long a device will hold the NDP packets received from the local device. After the aging timer expires, the device removes the received NDP neighbor node information.

Use the undo timer aging command to restore the default NDP information holdtime.

You can specify how long an adjacent device will hold the NDP information sent by the local device. An adjacent device holds the NDP information of the local switch according to the holdtime carried in the NDP packets received from the local switch and removes the NDP information when the aging timer expires.

The default holdtime is 180 seconds.

Note that NDP information holdtime is longer than the interval to send NDP packets normally. Otherwise, the neighbor information table of an NDP port will become unstable.

Example

# Configure the holdtime of the NDP information sent by the local switch to be 60 seconds.

<Sysname> system-view

[Sysname] ndp timer aging 60

1.1.4 ndp timer hello

Syntax

ndp timer hello hello-time

undo ndp timer hello

View

Parameter

Hello-time: Interval (in seconds) to send NDP packets ranging from 5 to 254.

Description

Use the ndp timer hello command to set the interval to send NDP packets.

Use the undo ndp timer hello command to restore the default interval to send NDP packets.

By default, the interval to send NDP packets is 60 seconds.

NDP information in a neighbor information table is updated regularly. This enables neighbor information table to contain the actual network topology information. You can use these two commands to adjust the updating frequency of NDP information.

Example

# Configure the interval to send NDP packets to be 80 seconds.

<Sysname> system-view

[Sysname] ndp timer hello 80

System view, Ethernet interface view

Parameter

None

Description

Use the ntdp enable command to enable NTDP globally or on a port.

Use the undo ntdp enable command to disable NTDP globally or on a port.

By default, NTDP is enabled globally and on ports.

Note that the NDTP cannot operate if it is enabled on a port where NDP is disabled.

Example

# Enable NTDP globally.

<Sysname> system-view

[Sysname] ntdp enable

# Enable NTDP for port GigabitEthernet 1/0/1.

1.2.4 ntdp explore

Syntax

ntdp explore

View

User view

Parameter

None

Description

Use the ntdp explore command to start topology information collection manually.

Normally, NTDP collects network topology information periodically. You can also start topology information collection manually whenever needed by executing this command. When you execute this command, NTDP collects the NDP information of every device and the information about the connections between the local switch and all of its neighbor switches in the specified network scope. The information is useful for the management device or network management system to acquire the network topology and to manage and monitor the devices.

Example

# Start the topology collection.

<Sysname> ntdp explore

1.2.5 ntdp hop

Syntax

ntdp hop hop-value

undo ntdp hop

View

System view

Parameter

hop-value: Maximum hops for collecting topology information, ranging from 1 to 16.

Description

Use the ntdp hop command to set a range (in terms of hop count) for topology information collection.

Use the undo ntdp hop command to restore the default range for topology information collection.

By default, the value is 3.

Note that:

l With the ntdp hop command, you can specify to collect the topology information of the devices within a specified range to avoid infinitive collection. The limit is performed by controlling the permitted hops from collection origination. For example, if you set the hop number limit to 2, only the switches less than 2 hops away from the switch starting the topology collection are collected.

l Note that this command is only applicable to the topology-collecting device. A broader collection scope requires more memory of the topology-collecting device.

Example

# Set the hop count for topology information collection to 5.

<aaa_0.Sysname> system-view

[aaa_0.Sysname] ntdp hop 5

1.2.6 ntdp timer

Syntax

ntdp timer interval-time

undo ntdp timer

View

System view

Parameter

interval-time: Interval (in minutes) to collect topology information, ranging from 0 to 65,535. This argument defaults to 1, argument 0 specifies not to collect topology information.

Description

Use the ntdp timer command to configure the interval to collect topology information.

Use the undo ntdp timer command to restore the default interval.

By default, the interval to collect topology information is 1 minute.

Note that:

l The (disable) prompt in the timer field of the display ntdp command means that the device is not the member of the cluster and does not perform periodical topology collection.

l After the cluster is set up, the S5500-SI switch will collect the topology information in the network at the set interval and add the detected candidate switches into the cluster automatically.

l If it is unnecessary to add the candidate switches into the cluster automatically, you can set the interval of topology collection to 0.

Example

# Set the interval to collect topology information to 30 minutes.

<aaa_0.Sysname> system-view

[aaa_0.Sysname] ntdp timer 30

1.2.7 ntdp timer hop-delay

Syntax

ntdp timer hop-delay time

undo ntdp timer hop-delay

View

System view

Parameter

time: Delay time (in milliseconds) for a switch to forward topology-collection request packets. This argument ranges from 1 to 1,000.

Description

Use the ntdp timer hop-delay command to set the delay time for a switch to forward topology-collection request packets.

Use the undo ntdp timer hop-delay command to restore the default delay time.

By default, the delay time for a switch to forward topology-collection request packets is 200 milliseconds.

Note that:

l To avoid network congestion caused by large amount of topology response packets received in short periods, a switch delays for specific period before it forwards a received topology-collection request packet through its first ports. You can use the ntdp timer hop-delay command to set the delay time.

l These two commands are intended for switches that collect topology information. They actually set the hop-delay value for topology-collection request packets sent by these switches. The hop-delay value determines the delay time for a switch receiving topology-collection request packets to forward them through its first port.

Example

# Set the delay time for the switch to forward topology-collection request packets through the first port to 300 ms.

<aaa_0.Sysname> system-view

[aaa_0.Sysname] ntdp timer hop-delay 300

1.2.8 ntdp timer port-delay

Syntax

ntdp timer port-delay time

undo ntdp timer port-delay

View

System view

Parameter

time: Delay time (in milliseconds) for a switch to forward a topology-collection request packet through its successive ports. This argument ranges from 1 to 100 and defaults to 20.

Description

Use the ntdp timer port-delay command to set the delay time for a switch to forward a received topology-collection request packet through its successive ports.

Use the undo ntdp timer port-delay command to restore the default delay time.

By default, the delay time for a switch to forward a received topology-collection request packet through its successive ports is 20 milliseconds.

Note that:

l To avoid network congestion caused by large amount of topology response packets received in short periods, a switch delays for specific period before it forwards a received topology-collection request packet through the next port. You can use the ntdp timer port-delay command to set the delay time.

l These two commands are intended for switches that collect topology information. They actually set the port-delay value for topology-collection request packets sent by these switches. The port-delay value determines the delay time for a switch receiving topology-collection request packets to forward them through the next port.

Example

# Set the delay time for the switch to forward topology-collection request packets through the successive ports to 40 ms.

<aaa_0.Sysname> system-view

[aaa_0.Sysname] ntdp timer port-delay 40

1.3 Cluster Configuration Commands

1.3.1 add-member

Syntax

add-member [ member- number] mac-address mac-address [ password password ]

View

Cluster view

Parameter

member-number: Member number assigned to the candidate device to be added to a cluster. This argument ranges from 1 to 255.

mac-address: MAC address of the candidate device (in hexadecimal).

password: Password of the candidate device, a string comprising 1 to 16 characters. The password is required when you add a candidate device to a cluster. However, this argument is not needed if the candidate device is not configured with a password.

Description

Use the add-member command to add a candidate device to a cluster.

Note that:

l You can add a candidate device to a cluster on the management device only.

l If you do not specify the member number when adding a cluster member, the management device assigns the least available member number to it.

l After a candidate device is added to a cluster, its device password becomes the management device password.

Caution:

If the number of the routing table entries of a candidate device reaches the maximum number allowed when the candidate is added to a cluster, it will be added to and removed from the cluster repeatedly.

Example

# Add a candidate device to the cluster, setting the member number to 6. (Assume that the MAC address and user password of the candidate device are 00E0-fc00-35e7 and 123456.)

<aaa_0.Sysname> system-view

[aaa_0.Sysname] cluster

[aaa_0.Sysname-cluster] add-member 6 mac-address 00E0-fc00-35e7 password 123456

1.3.2 administrator-address

Syntax

administrator-address mac-address name name

undo administrator-address

View

Cluster view

Parameter

mac-address: MAC address of the management device(in hexadecimal).

name name: Name of an existing cluster, a string comprising up to 8 characters, which can only be alphanumeric characters, subtraction sign (-), and underline (_).

Description

Use the administrator-address command to set the MAC address of the management device on a member device.

Use the undo administrator-address command to remove a member device from the cluster, usually for debugging or restoration.

By default, a switch belongs to no cluster.

Note that:

l administrator-address only can be executed on a candidate device, undo administrator-address only can be executed on a member device.

l A cluster contains one (and only one) management device. After rebooting, a member device identifies the management device by the MAC address of the management device.

l You are recommended to use the delete-member command to remove a cluster member from a cluster on the management device.

Example

# Remove a member device from the cluster.

<aaa_0.Sysname> system-view

[aaa_0.Sysname] cluster

[aaa_0.Sysname] undo administrator-address

1.3.3 auto-build

Syntax

auto-build [ recover ]

View

Cluster view

Parameter

recover: Establishes communication with all the member devices again.

Description

Use the auto-build command to build a cluster automatically.

Note that:

l This command can be executed on a candidate device or a management device.

l When you use this command on a candidate device, you will be required to enter the cluster name and build a cluster. Then the system will collect candidates and add the collected candidates into the cluster automatically.

l When you use this command on a management device, the system will collect candidates directly and add them into the cluster automatically.

l The recover keyword is used to recover a cluster. Using the auto-build recover command, you can find the members that are not currently in the member list and add them to the cluster again.

l Ensure that NTDP is enabled, because it is the basis of candidate and member collection. The collection range is also decided through NTDP. You can use the hop command in system view to modify the collection range.

l If a member is configured with a password different from the password of the management device, it cannot be added to the cluster automatically.

Caution:

When you configure a cluster, if the number of routing table entries reaches the maximum number allowed, no more routing table entries can be configured on a management device and candidate devices, which will result in the unreachability of handshake packets and the repeated add and removal of the device to and from the cluster:

l If the routing table entries of the management device reach the maximum number allowed when a cluster is created, all candidate devices will be added to and removed from the cluster repeatedly.

l If the number of the routing table entries of a candidate device reaches the maximum number allowed when the candidate device is added to a cluster, it will be added to and removed from the cluster repeatedly.

Example

# Set up a cluster automatically.

1.3.6 build

Syntax

build name

undo build

View

Cluster view

Parameter

name: Cluster name, a string comprising up to 8 characters, which can only be alphanumeric characters, subtraction sign (-), and underline (_).

Description

Use the build command to configure the current device as the management device and specify a name for it. When executing this command, you will be asked whether you want to create a standard topology map or not.

Use the undo build command to remove a cluster.

If the build command is executed on the candidate device, the current switch will be configured as the management device and assigned with a cluster name.

If the build command is executed on the management device, the cluster name will be modified.

Note that:

l This command can only be applied to devices that are capable to be a management device and are not members of other clusters. The command takes no effect if you execute the command on a device which is already a member of another cluster. If you execute this command on a management device, you will replace the cluster name with the one you specify.

l The member number of a management device is 0.

After the cluster is set up, the S5500-SI switch will collect the topology information of the network at the set interval and add the detected candidate devices into the cluster automatically. If it is unnecessary to add the candidate switches into the cluster automatically, you can set the interval of topology collection to 0, that is, topology collection is not performed periodically.

Example

# Configure the current switch to be a management device and specify the cluster name to be aabbcc.

<Sysname>system-view
