1.1.2 ndp enable

Syntax

ndp enable [ interface port-list ]

undo ndp enable [ interface port-list ]

View

System view, Ethernet port view

Parameters

Description

In system view:

Use the ndp enable command to enable NDP globally.

Use the undo ndp enable command to disable NDP globally.

When the ndp enable command is executed in system view, the NDP feature is enabled globally if the port-list argument is not specified, while the NDP feature is enabled on the specified port if the port-list argument is specified.

In Ethernet port view:

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

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

When this command is used in Ethernet port view, the interface keyword cannot be provided and the NDP feature is enabled on the current port only.

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

Note that the NDP feature on a port does not take effect until the NDP feature is enabled globally.

Examples

# Enable NDP globally.

1.1.3 ndp timer aging

Syntax

ndp timer aging aging-in-seconds

undo ndp timer aging

View

System view

Parameters

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

The default holdtime is 180 seconds.

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.

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.

Examples

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

1.2.3 ntdp enable

Syntax

ntdp enable

undo ntdp enable

View

System view, Ethernet port view

Parameters

None

Description

In system view:

Use the ntdp enable command to enable NTDP globally.

Use the undo ntdp enable command to disable NTDP globally.

In Ethernet port view:

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

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

By default, NTDP is enabled globally and on ports.

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

& Note:

l On a management device, NTDP must be enabled globally and on all the ports, and the NTDP parameters must be configured. On a member device, NTDP must be enabled globally and on the corresponding port. When NTDP is running on member devices, it adopts the NTDP parameters from the management device.

l NTDP takes effect in the management VLAN only. The S7500 series take VLAN 1 as the default VLAN, that is, the NTDP feature of the S7500 series takes effect in VLAN 1 only.

Examples

# Enable NTDP globally.

1.2.4 ntdp explore

Syntax

ntdp explore

View

User view

Parameters

None

Description

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

You can use this command to enable the topology information collection manually. NTDP will collect the NDP information of every device and the information about the connections between the local switch and all of its neighbor devices in the specified network scope. The management device or the network administrator uses this information to acquire the network topology to manage and monitor the devices.

Examples

# Start the topology collection.

<aaa_0.H3C> ntdp explore

1.2.5 ntdp hop

Syntax

ntdp hop hop-value

undo ntdp hop

View

System view

Parameters

hop-value: Maximum hops for collecting topology information, ranging from 1 to 128. By default, the value is 3.

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.

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.

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

Examples

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

Parameters

interval-in-minutes: Interval (in minutes) to collect topology information, ranging from 0 to 65,535. This argument defaults to 0, which 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 0 minutes, that is, topology information is not collected periodically.

A switch collects topology information once in each period set by the ntdp timer command.

Examples

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

1.2.7 ntdp timer hop-delay

Syntax

ntdp timer hop-delay time

undo ntdp timer hop-delay

View

System view

Parameters

time: Delay time (in milliseconds) for a switch to forward topology-collection request packets. This argument ranges from 1 to 1,000 and defaults to 200.

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.

To avoid network congestion caused by a large amount of topology response packets received by the topology collection device in a short period, 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.

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.

Examples

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

<aaa_0.H3C> system-view

System View: return to User View with Ctrl+Z.

[aaa_0.H3C] 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

Parameters

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 port (on the device whose topology information is collected) to wait to forward topology-collection request packets after the last port (on the device whose topology information is collected) forwards topology-collection request packets.

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

By default, the delay time of a port is 20 ms.

To avoid network congestion caused by a large amount of topology response packets received by the topology collection device in short periods, a switch delays for a 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.

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.

Examples

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

1.3 Cluster Configuration Commands

1.3.1 add-member

Syntax

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

View

Cluster view

Parameters

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

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

password: Password of the candidate device, a string comprising 1 to 256 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.

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

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

After a candidate device is added to a cluster, the level-3 password of the device is replaced by the password of the management device automatically.

Examples

# Add a candidate device to the cluster, setting the member number to 6. (Assume that the MAC address and level-3 user password of the candidate device are 00E0-fc00-35e7 and 123456.)

1.3.2 administrator-address

Syntax

administrator-address mac-address name name

undo administrator-address

View

Cluster view

Parameters

mac-address: MAC address of the management device.

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.

By default, a switch belongs to no cluster.

In order that the member devices identify the management device correctly after the system is restarted, the administrator-address command is enabled automatically on the switch to specify the MAC address of the management device in the cluster when the switch is added to the cluster as a member device.

Note that the undo administrator-address command is generally used in debugging or restoration. You are recommended to use the delete-member command to remove a cluster member from a cluster on the management device.

Examples

# Remove a member device from the cluster.

1.3.3 auto-build

Syntax

auto-build [ recover ]

View

Cluster view

Parameters

recover: Establishes communication with all the member devices again.

Description

Use the auto-build command to add the candidate device to the cluster automatically to be a member device.

This command can be executed on a management device or a device to be configured as a management device.

When you use this command on a candidate device, you will be required to enter the cluster name and build a cluster. The system will collect candidate devices automatically and then it is for the user to decide whether to add the collected candidate devices into the cluster.

When you use this command on a management device, the system will collect candidate devices automatically.

The recover keyword is used to recover a cluster. Execute the auto-build recover command to look for the down members in the member list and add them to the cluster again.

Note: 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 ntdp hop command in system view to modify the collection range.

If a member device is configured with a level-3 user password different from that of the management device, it cannot be added to the cluster automatically.

1.3.13 ftp-server

Syntax

ftp-server ip-address

undo ftp-server

View

Cluster view

Parameters

ip-address: IP address of the FTP server to be configured for the cluster.

Description

Use the ftp-server command to configure an FTP server on the management device for the member devices in the cluster.

Use the undo ftp-server command to remove the FTP server configured for the member devices in the cluster.

By default, the management device acts as the FTP Server.

You need to configure the IP address of an FTP server first for the member devices in a cluster to access the FTP server through the management device.

Examples

# Configure the IP address of an FTP server on the management device.

1.3.14 holdtime

Syntax

holdtime seconds

undo holdtime

View

Cluster view

Parameters

seconds: Holdtime (in seconds), ranging from 1 to 255. The default value is 60.

Description

Use the holdtime command to configure the holdtime of a switch.

Use the undo holdtime command to restore the default holdtime value.

l If a switch does not receive any information of a peer device during the holdtime, it sets the state of the peer device to “down”. When the communication resumes, the corresponding member device is re-added to the cluster (automatically).

l If the downtime does not exceed the holdtime, the member device stays in the normal state and does not need to be added again.

Execute these two commands on management devices only. The member devices in a cluster acquire the holdtime setting from the management device.

Examples

# Set the holdtime to 30 seconds.

<aaa_0.H3C> system-view

System View: return to User View with Ctrl+Z

1.3.15 ip address

Syntax

ip address ip-address { mask | mask-length }

undo ip address ip-address { mask | mask-length }

View

VLAN interface view

Parameters

ip-address: IP address of the VLAN interface, expressed in dotted decimal.

mask: Subnet mask of the VLAN interface IP address, expressed in dotted decimal.

mask-length: Length of the subnet mask, namely, the number of “1”s in the subnet mask.

Description

Use the ip address command to specify an IP address and subnet mask for the VLAN interface.

Use the undo ip address command to remove the IP address and subnet mask of the VLAN interface.

By default, the IP address of a VLAN interface is null.

Note that:

l The S7500 series use VLAN 1 as the cluster management VLAN to manage the cluster.

l The IP address of the Layer 3 virtual interface of the management VLAN must be configured before a cluster is set up; otherwise, the cluster cannot be set up successfully.

l When a cluster is set up, the IP address of the management VLAN interface cannot be modified any more.

Examples

# Specify the IP address of VLAN interface 1 as 129.12.0.1 and the subnet mask as 255.255.255.0.

1.3.16 ip-pool

Syntax

ip-pool administrator-ip-address { ip-mask | ip-mask-length }

undo ip-pool

View

Cluster view

Parameters

administrator-ip-address: IP address of the management device of a cluster.

ip-mask: Mask of the cluster IP address pool.

ip-mask-length: Mask length of the cluster IP address pool.

Description

Use the ip-pool command to configure a private IP address range for cluster members on the switch to be configured as the management device.

Use the undo ip-pool command to cancel the IP address range configuration.

Before establishing a cluster, you need to configure a private IP address pool for the switches to be added to the cluster. When a candidate device is added to a cluster, the management device assigns a private IP address to it for the candidate device to communicate with other devices in the cluster. This enables you to manage and maintain member devices in a cluster through the management device.

Execute these two commands on switches that do not belong to any cluster only. The IP address range of an existing cluster cannot be modified.

Examples

# Configure the IP address range of a cluster.

Parameters

ip-address: IP address of the logging host configured for the cluster.

Description

Use the logging-host command to configure a logging host on the management device for the member devices in the cluster.

Use the undo logging-host command to remove the public logging host for the member devices in the cluster.

By default, no logging host is configured.

You need to configure the IP address of a logging host first for the member devices in a cluster to send log information to the logging host through the management device.

Examples

# Configure the IP address of the logging host on the management device.

<aaa_0.H3C> system-view

System View: return to User View with Ctrl+Z

[aaa_0.H3C] cluster

Parameters

member-number: Member number of a switch in a cluster, ranging from 1 to 255.

mac-address H-H-H: MAC address of the member device to be rebooted.

eraseflash: Deletes the configuration file when the member device reboots.

Description

Use the reboot member command to reboot a specified member device on the management device.

Communication between the management and member devices may be interrupted due to some configuration errors. Through the remote control function of member devices, you can control them remotely on the management device. For example, you can reboot a member device that operates improperly and specify to delete the booting configuration file when the member device reboots, and thus restore normal communication between the management and member devices.

The eraseflash keyword specifies to delete the booting configuration file when the member device reboots.

Examples

# Reboot the member device numbered 2.
