By default, the domain ID of an
IRF fabric is 0.
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.
