Verifying the ISSU State Before Beginning the ISSU Process

Ensure that the active and standby supervisor engines are up and in ISSU Init state and that the boot
variables are set and pointing to valid files.
The following example displays the ISSU state before the process begins:
Switch# show issu state detail
OL-25340-01
Manual Swact = enabled
keep_alive TMR = 9000 milliseconds
keep_alive count = 0
keep_alive threshold = 18
RF debug mask = 0x0
Available system uptime = 1 minute
Standby failures = 0
Last switchover reason = none
Hardware Mode = Duplex
Configured Redundancy Mode = Stateful Switchover
Operating Redundancy Mode = Stateful Switchover
Maintenance Mode = Disabled
Communications = Up
Active Location = slot 1
Current Software state = ACTIVE
Uptime in current state = 0 minutes
Image Version = Cisco IOS Software, Catalyst 4500 L3 Switch Software
BOOT = bootflash:old_image,1;
Configuration register = 0x822
Standby Location = slot 2
Current Software state = STANDBY HOT
Uptime in current state = 1 minute
Image Version = Cisco IOS Software, Catalyst 4500 L3 Switch Software
BOOT = bootflash:old_image,1;
Configuration register = 0x822
Slot = 1
RP State = Active
