Verifying the ISSU State Before Beginning the ISSU Process

Ensure that both the supervisor engines are configured to auto-boot, and that they have currently been
booted from the pre-upgrade image residing on the local file system. This is verified by the values of the
BOOT variable and the configuration register (refer to the sample output of show redundancy command
in the previous section).
Ensure that the active and standby supervisor engines are up and in ISSU Init state and that both
supervisor engines are running the same current image.
The following example displays the ISSU state before the process begins:
Switch# show issu state detail
bootflash:cat4500e-universal.SSA.03.03.00.SGN1.33.151-2.SGN1.33.bin
bootflash:cat4500e-universal.SSA.03.03.00.SGN1.33.151-2.SGN1.33.bin
Note that the Standby slot number is reported as 11, which is a Virtual Slot number that corresponds to
physical slot 1 on Switch 2. The correspondence between the Virtual Slot number and the physical
location of the slot can be determined using the show switch virtual slot-map command, as shown in
the following example:
Switch# show switch virtual slot-map
