IRF commands
chassis convert mode irf
Use chassis convert mode irf to enable IRF mode.
Use undo chassis convert mode to restore standalone mode.
Syntax
chassis convert mode irf
undo chassis convert mode
Default
The device operates in standalone mode.

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.

# Display IRF fabric information.
<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
p
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
p
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.
