Hi all,
I was upgrading IOS on 4507 R with dual supervisior.
I download the IOS on Active supervisior and did reboot.
After reboot i login to switch then i got switch standby prompt.
I found that after reboot active supervisior became standby supervisior.
Now new IOS is on standby supervisior.
Need to confirm below
So this means that IOS does not syn within the supervisiors as compared to config right ?
Which command i can use that will copy IOS from standby supe to Active supe??
Which command i can use that will show both active and standby supe with new IOS?
Is there any command that i can use to switchover from active to standby supe??
Thanks
MAhesh

Hi Mahesh,

No, the only the config will sync between the 2 sups. You have to manually load the IOS in to the other sup.
Which command i can use that will copy IOS from standby supe to Active supe??
Which command i can use that will show both active and standby supe with new IOS?
use "show redun" that will show you if both sups are configured correctly, is yes the mode should be SSO and one the primary sup should be in "Active" and the stand-by sup should be "Hot"
Is there any command that i can use to switchover from active to standby supe??
Once you load the SAME EXACT IOS into both sups, configure SSO on the primary sup and reboot the switch.
When the switch comes online sup in slot 3 should be in active mode and 4 in stand-by mode. Make sure that both sups have the same IOS and the same hardware components, and are exactly the same model.
