chassis convert mode irf
Use chassis convert mode irf to enable IRF mode.
Use undo chassis convert mode to restore the default.
Syntax

Usage guidelines
To set up an IRF fabric, place all member devices in IRF mode after you configure member IDs,
priorities, and IRF port settings for the member devices. 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 devices. To conserve system resources, set a device to standalone mode after removing it
from an IRF fabric.
Examples
# (Centralized devices in standalone mode.) 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...
Saving the converted configuration file to the main board succeeded.
# (Centralized devices in IRF mode.) 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...
Saving the converted configuration file to the main board succeeded.
# (Distributed devices in standalone mode.) 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 cfa0:/startup.cfg
to make it available in IRF mode? [Y/N]:y
Now rebooting, please wait...
Saving the converted configuration file to the main board succeeded.
Slot 1:

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.
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.
Auto merge Status of the IRF auto-merge feature:
•yes—Enabled.
•no—Disabled.
