Assigning A Member Id To Each Irf Member Switch; Specifying A Priority For Each Member Switch; Binding Physical Ports To Irf Ports - HP 7500 series Configuration Manual

Assigning a member ID to each IRF member switch

A switch by default operates in standalone mode without an IRF member ID. You must assign it a unique
IRF member ID before changing its operating mode to IRF.
The member ID assigned to a switch is saved in both active and standby MPUs of the switch. If the
standby MPU has a different member ID than the active MPU, for example, because of an MPU
replacement, the member ID in the active MPU takes effect and is automatically updated to the standby
MPU.
Execute the display irf configuration command and look at the MemberID field. If the switch has no IRF
member ID, the field displays two hyphens (--).
Configuration restrictions and guidelines
If the switch is installed with an LSQ1SRP1CB card, its member ID must be 1 or 2.
The member ID of a 7510 switch must be 1 or 3.
If the 7506 or 7506-V switch is assigned member ID 4, the card in slot 7 by default cannot work. To
resolve the problem for a four-chassis 7506 or 7506-V IRF fabric, use the irf-pbr disable command as
described in
are setting a 7506 or 7506-V IRF fabric that has fewer members, do not assign member ID 4 to any
member switch.
Configuration procedure
To set a member ID for the switch in standalone mode:
Step
1. Enter system view.
2. Assign an IRF member ID to
the switch.

Specifying a priority for each member switch

IRF member priority represents the possibility for a device to be elected the master in an IRF fabric. The
higher the priority, the higher the possibility.
To specify a priority for the switch:
Step
1. Enter system view.
2. Specify a priority for the
switch.

Binding physical ports to IRF ports

To establish an IRF connection, you must bind the physical ports that connect IRF member switches to IRF
ports. For link redundancy and load sharing, bind multiple physical ports to one IRF port.
In standalone mode, binding a physical port to an IRF port does not affect the current configuration of the
port. However, when the operating mode changes to IRF mode, the default configuration of the physical
