Use display irf to display IRF fabric information, including the member ID, role, priority, bridge MAC
address, and description of each IRF member.
Syntax
display irf

# Display IRF fabric information.
<Sysname> display irf
MemberID Role Priority CPU-Mac Description
1 Standby 1 00e0-fc0f-8c02 F1Num001
*+2 Master 1 00e0-fc0f-8c03 F1Num002
--------------------------------------------------------
* indicates the device is the master.
+ indicates the device through which the user logs in.
The Bridge MAC of the IRF is: 00e0-fc00-1000
Auto upgrade : yes
Mac persistent : always
Domain ID : 30
IRF mode : normal
Table 1 Command output
Field Description
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.
Role
Role of the member device in the IRF fabric:
•Standby—Subordinate device.
•Master—Master device.
•Loading—The device is loading software images.
Priority IRF member priority.
CPU-MAC MAC address of the CPU in the device.

Field Description
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.
The Bridge MAC of the
IRF is Bridge MAC address of the IRF fabric.
Auto upgrade
Status of the software auto-update feature:
•yes—Enabled. The master propagates its software images automatically to
the device you are adding to the IRF fabric.
•no—Disabled. You must manually make sure the joining device uses the
same software images as the master. If the software images are different,
the new device cannot join the IRF fabric.
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.
Domain ID Domain ID of the IRF fabric. The domain ID you assign to an IRF fabric must
uniquely identify the fabric in a multi-IRF fabric network.
IRF mode IRF mode of the IRF fabric. This field is not supported in the current software
version.
