ISSU upgrade example

Network status

As shown in
Distribution layer switches Switch D, Switch E, and Switch form an IRF fabric. The member ID of the master
is 1, and those of the subordinate switches are 2 and 3.
To ensure high availability, configure cross-device link aggregation using the following guidelines so
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.
