Modifying a member ID for a switch
An IRF fabric uses member IDs to uniquely identify its members. A lot of information and configurations
relate to member IDs, such as port (physical or logical) numbers, configurations on ports, and member
priorities.
After you change the member ID of a switch:
• If you do not reboot the switch, the original member ID still takes effect and all physical resources
are identified by the original member ID. In the configuration file, only the IRF port numbers,
configurations on IRF ports, and priority of the switch change with the member ID, other
configurations do not change.
• If you save the current configuration and reboot the switch, the new member ID takes effect and all
physical resources are identified by the new member ID. In the configuration file, only the IRF port
numbers, configurations on IRF ports, and priority of the switch still take effect, other configurations
(such as configuration for physical IRF ports, value of the chassis keyword which adopts the original
member ID) no longer take effect and you need to configure them again.
Follow these steps to modify a member ID for a member switch:
To do… Use the command… Remarks
Enter system view system-view —
Modify a member ID for a
member switch irf member member-id renumber
new-member-id
Optional
The switch has no default ID in
standalone mode. After it
switches to the IRF mode, it uses
the member ID pre-configured in
standalone mode by default.
CAUTION:
•
Member ID changes take effect at the reboot of the switch.
• Change member IDs for the switches in an IRF fabric with caution. The change might cause
configuration change and even data loss.
• Different switch models and cards have different requirements for member IDs. See “Setting a member
ID for the switch.”
Specifying a priority for a member switch
Follow these steps to specify a priority for a member switch:
To do… Use the command… Remarks
Enter system view system-view —
Specify a priority for a member of
an IRF fabric
irf member member-id priority priority
Optional
The priority of a member defaults
to 1.
Configuring IRF ports
After an IRF fabric is formed, you can add physical ports used to connect member switches.
