IRF commands

Usage guidelines

To set up an IRF fabric, place all its member devices in IRF mode after configuring their member IDs,

priorities, and IRF port settings. In standalone mode, a device cannot form an IRF fabric with other

devices.

IRF generates packets on a device in IRF mode even if the device does not form an IRF fabric with any

other device. To protect system resources, set a device to operate in standalone mode after removing it

from an IRF fabric.

Examples

# Enable IRF mode.

<Sysname> system-view

[Sysname] chassis convert mode irf

The device will switch to IRF mode and reboot. You are recommended to save the current

running configuration and specify the configuration file for the next startup. Continue?

[Y/N]:y

Do you want to convert the content of the next startup configuration file flash:/startup.cfg

to make it available in IRF mode? [Y/N]:y

Now rebooting, please wait...

System is starting...

# Restore standalone mode.

<Sysname> system-view

[Sysname] undo chassis convert mode

The device will switch to stand-alone mode and reboot.

You are recommended to save the current running configuration and specify the configuration

file for the next startup. Continue? [Y/N]:y

Do you want to convert the content of the next startup configuration file flash:/startup.cfg

to make it available in stand-alone mode? [Y/N]:y

Now rebooting, please wait...

System is starting...

display irf

Use display irf to display IRF fabric information, including the member ID, role, priority, bridge MAC

address, and description of each IRF member.

<Sysname> display irf

MemberID Slot Role Priority CPU-Mac Description

*+1 16 Master 1 0210-fc03-0007 -----

--------------------------------------------------

* indicates the device is the master.

+ indicates the device through which the user logs in.

The Bridge MAC of the IRF is: 3ce5-a6b8-3800

Auto upgrade : no

Mac persistent : always

Domain ID : 0

Auto merge : no

Table 1 Command output

Field Descri

tion

MemberID

IRF member ID:

•ID of the master is prefixed with an asterisk (*) sign.

•ID of the device where you are logged in is prefixed with a plus (+) sign.

Slot MPU slot number.

Field Descri

tion

Role

Role of the MPU in the IRF fabric:

•Standby—Standby MPU for the global active MPU.

•Master—Global active MPU.

•Loading—Standby MPU for the global active MPU. The standby MPU is

loading software images.

Priority IRF member priority.

CPU-MAC MAC address of the CPU on the MPU.

Description

Description you have configured for the member device.

•If no description is configured, this field displays a dashed line (-----).

•If the description exceeds the maximum number of characters that can

be displayed, an ellipsis (…) is displayed in place of the exceeding text.

To display the complete description, use the display

current-configuration command.

Auto upgrade

This field is not supported in the current software version.

Status of the software auto-update feature:

•yes—Enabled.

•no—Disabled.

MAC persistent

IRF bridge MAC persistence setting:

•6 min—Bridge MAC address of the IRF fabric remains unchanged for 6

minutes after the address owner leaves.

•always—Bridge MAC address of the IRF fabric does not change after

the address owner leaves.

•no—Bridge MAC address of the current master replaces the original

bridge MAC address as soon as the owner of the original address

leaves.

Auto merge

State of the auto-merge feature:

•yes—Enabled. The IRF fabric automatically reboots its member devices

when it fails in the master election during an IRF fabric merge.

•no—Disabled. Manual reboot is required to complete an IRF fabric

merge.

display irf configuration

Use display irf configuration to display basic IRF settings, including the current member ID, new member

ID, and physical interfaces bound to the IRF ports on each IRF member device. The new member IDs take

effect at reboot.

Table 2 Command output

Field Descri

tion

MemberID Current member ID of the device.

If no member ID is assigned, this field displays two hyphens (--).

Priority Member priority.

This field is available when the device is operating in standalone mode.

NewID Member ID assigned to the device. This member ID takes effect at reboot.

This field is available when the device is operating in IRF mode.

IRF-Port1 Physical interfaces bound to IRF-port 1. The bindings take effect at reboot.

This field displays disable if no physical interfaces are bound to the IRF port.

IRF-Port2 Physical interfaces bound to IRF-port 2. The bindings take effect at reboot.

This field displays disable if no physical interfaces are bound to the IRF port.

display irf link

Use display irf link to display IRF link information, including IRF ports, IRF physical interfaces, and IRF

link status.
