T h e m e m b e r I D o f t h e m a s t e r is 1, and those of the subordinate switches are 2 and 3 respectively. To ensure high availability, configure cross-device link aggregation using the following guidelines so that every three physical links with the same color between the IRF member switches and access switches are aggregated as one logical link: • On the IRF fabric, create three dynamic aggregation groups. Ports in aggregation group 1 connect to Switch A, ports in aggregation group 2 connect to Switch B, and ports in aggregation group 3 connect to Switch C. • On Switch A, create aggregation group 1 that corresponds to aggregation group 1 on the IRF fabric. • On Switch B, create aggregation group 2 that corresponds to aggregation group 2 on the IRF fabric. • On Switch C, create aggregation group 3 that corresponds to aggregation group 3 on the IRF fabric. Network requirements The current system software image on each IRF member switch is soft-version1.bin. The new system software image soft-version2.bin is saved on the TFTP server. The IP address of the IRF fabric is 1.1.1.1/24, and that of the TFTP server is 2.2.2.2/24. The IRF fabric and the TFTP server can reach each other. Use ISSU to upgrade system software of the IRF member switches to avoid traffic interruption.

{ The member ID and the priority of the master is 1 and 10 respectively
{ The member ID and the priority of one subordinate switch is 2 and 9 respectively
{ The member ID and the priority of the other subordinate switch is 3 and 1 respectively
During the ISSU upgrade process, you must se lect subordinate switch 2 as the specified
subordinate switch.
Before performing compatible ISSU, make sure the priorities of the master switch and the specified
subordinate switch are higher than other IRF memb er switches so that the specified subordinate
switch can be elected as the new master after the master is rebooted. Otherwise, modify the
priorities of the master switch and the specified subordinate switch with the irf member member-id
priority priority command.
