Redundant System Information :

------------------------------

Available system uptime = 2 days, 13 hours, 58 minutes

Switchovers system experienced = 0

Standby failures = 0

Last switchover reason = none

Hardware Mode = Simplex

Configured Redundancy Mode = Stateful Switchover

Operating Redundancy Mode = Stateful Switchover

Maintenance Mode = Disabled

Communications = Down Reason: Simplex mode

Switch#show redundancy states

my state = 13 -ACTIVE

peer state = 1 -DISABLED

Mode = Simplex

Unit = Primary

Unit ID = 6

Redundancy Mode (Operational) = Stateful Switchover

Redundancy Mode (Configured) = Stateful Switchover

Redundancy State = Non Redundant

Maintenance Mode = Disabled

Manual Swact = disabled (system is simplex (no peer unit))

Communications = Down Reason: Simplex mode

client count = 57

client_notification_TMR = 240000 milliseconds

keep_alive TMR = 9000 milliseconds

keep_alive count = 0

keep_alive threshold = 18

RF debug mask = 0x0

I have this problem too.

Hi Sumit,

The reason for this is your chaissis is not detecting the SUP.

Was there any changes made before this issue occured.

Check if the primary is in rommon ,try to reload the primary.

you are right, the sup is in rommon mode,

1 question, if i will use console cable and insert "reload" command, that is going to reboot the entire switch... and we cannot afford to take a risk as our entire management is connected to the same switch...we cannot afford a downtime of even seconds....please advise
