Usage guidelines

CAUTION

CAUTION:

The default command might interrupt ongoing network services. Make sure you are fully aware of the impacts of this command when you execute it on a live network.

 

This command might fail to restore the default settings for some commands for reasons such as command dependencies and system restrictions.

To resolve this problem:

1.     Use the display this command in interface view to identify these commands.

2.     Use their undo forms or follow the command reference to restore their default settings.

3.     If the restoration attempt still fails, follow the error message instructions to resolve the problem.

Examples

# Restore the default settings for Reth 1.

<Sysname> system-view

[Sysname] interface reth 1

[Sysname-Reth1] default

description

Use description to configure the description of an interface.

Use undo description to restore the default.

Default

No Reth interfaces exist.

Views

System view

Predefined user roles

network-admin

mdc-admin

Parameters

interface-number: Specifies a Reth interface by its number. The value for this argument is 1 or 2.

Usage guidelines

A Reth interface is a virtual Layer 3 interface that uses two member interfaces to ensure link availability.

You cannot delete a Reth interface if it has member interfaces.

Examples

# Create Reth 1 and enter its view.

<Sysname> system-view

[Sysname] interface reth 1

[Sysname-Reth1]

member interface

Use member interface to assign a member interface to a Reth interface.

Use undo member interface to remove a member interface from a Reth interface.

Syntax

member interface interface-type interface-number priority priority

undo member interface interface-type interface-number

Default

A Reth interface does not have member interfaces.

Views

Reth interface view

Predefined user roles

network-admin

mdc-admin

Parameters

interface-type interface-number: Specifies an interface by its type and number. The interface must be a management Ethernet port.

priority: Specifies an interface priority in the range of 1 to 255. The higher the value, the higher the interface priority.

Usage guidelines

You can assign a maximum of two member interfaces to a Reth interface. An interface can belong to only one Reth interface.

As a best practice, assign interfaces of the same type and same speed to a Reth interface.

When the two member interfaces of a Reth interface are up, the system chooses the interface with the higher priority as the active interface to forward packet. The interface with the lower priority is inactive and cannot forward packets.

Do not specify a Reth interface as the outgoing interface in IPv6 static neighbor entries if its member interfaces contain subinterfaces. For more information about IPv6 static neighbor entries, see Layer 3—IP Services Configuration Guide.

Examples

# Assign M-GigabitEthernet 1/0/0/1 and M-GigabitEthernet 1/1/0/2 to Reth 1, and set their priority to 100 and 50, respectively.

<Sysname> system-view

[Sysname] interface reth 1

[Sysname-Reth1] member interface M-GigabitEthernet 1/0/0/1 priority 100

[Sysname-Reth1] member interface M-GigabitEthernet 1/0/0/2 priority 50

mtu

Use mtu to set the MTU of a Reth interface.

Use undo mtu to restore the default.

Syntax

mtu size

undo mtu

Default

The MTU is 1500 bytes for a Reth interface.

Views

Reth interface view

Predefined user roles

network-admin

mdc-admin

Parameters

size: Specifies the MTU in bytes. The value range for this argument is 46 to 1500.

Usage guidelines

The MTU size of a Reth interface affects the fragmentation and reassembly of IP packets on the interface.

For the configured MTU size to take effect, execute the shutdown command, and then the undo shutdown command on the interface.

Examples

# Set the MTU to 200 bytes for Reth 1.

<Sysname> system-view

[Sysname] interface reth 1

[Sysname-Reth1] mtu 200

If you do not specify the reth keyword, the command clears statistics for all interfaces. If you specify the reth keyword without the interface-number argument, the command clears statistics for all Reth interfaces.

Usage guidelines

Use this command to clear history statistics before you collect traffic statistics for a time period.

Examples

# Clear statistics for Reth 1.

<Sysname> reset counters interface reth 1

Parameters

interface-type interface-number: Specifies a physical interface by its type and number. The interface must belong to the IRF member device that is bound to the node.

Usage guidelines

Before you assign physical Ethernet interfaces to a redundancy group node, you must use the bind chassis command to bind the node to an IRF member device.

Usage guidelines

By default, the high-priority node is the primary node, and the low-priority node is the secondary node. If both nodes have the same priority, the lower-numbered node is the primary node.

Examples

# Set the priority to 3 for node 1 of redundancy group aaa.

interface interface-type interface-number: Specifies an interface by its type and number. The interface will be excluded from the shutdown action by the Reth module. If you do not specify this option, no interface is excluded from the shutdown action by the Reth module. You must specify the tracked interface for this option if the interface has one of the following roles:

·     Member of the redundancy group.

·     Member of a Reth interface in the redundancy group.

Usage guidelines

You can associate a maximum of 64 track entries with a redundancy group node.

As a best practice, associate a redundancy group node with an existing track entry. If the track entry does not exist, a switchover might occur.

Do not exclude a subinterface from the shutdown action if both the subinterface and its main interface have one of the following roles on the high-priority node:

·     Member of the redundancy group.

·     Member of a Reth interface in the redundancy group.

When the Reth module shuts down the main interface, the subinterface is also shut down. The shutdown subinterface cannot recover automatically to trigger an automatic switchover.

Examples

# Associate track entries 1 and 2 with redundancy group node 1. Exclude FortyGigE 1/1/0/1 and FortyGigE 2/1/0/1 from the shutdown action by the Reth module.
