Usage guidelines

Perform an ISSU switchover to upgrade the master after you execute the issu load command to upgrade the subordinate device.

The issu load command separates the upgraded subordinate device from the existing IRF fabric to form a new IRF fabric. When you execute the issu run switchover command, the master in the old IRF fabric reboots to join the new IRF fabric as a subordinate member.

Before you execute the issu run switchover command on the old master, make sure the new master has finished synchronizing its configuration and status data with the old master. To examine the synchronization progress, use the display device and display system internal ha service-group commands on the new IRF fabric. The synchronization is completed if the following conditions are met:

• All cards of the device are in Normal state.

• The Action field of the display system internal ha service-group command is 0 for each service.
