my costumer is working with a 6509-E chassis running two WS-SUP720-3B with 12.2(33)SXI2a.
Redundancy mode is SSO but the state is DISABLED, why?
c6500-P3b#show redundancy states
my state = 13 -ACTIVE
peer state = 1 -DISABLED
Mode = Simplex
Unit = Primary
Unit ID = 5
Redundancy Mode (Operational) = sso
Redundancy Mode (Configured) = sso
Redundancy State = Non Redundant
Maintenance Mode = Disabled
Communications = Down Reason: Simplex mode
client count = 119
client_notification_TMR = 30000 milliseconds
keep_alive TMR = 9000 milliseconds
keep_alive count = 0
keep_alive threshold = 18
RF debug mask = 0x0
How can I start troubleshooting?
start to see from sh module what is the current state of standby supervisor.
it is likely in rommon state.
see following documents about recovering a sup in rommon
Also be aware that the presence of service modules like NAM can affect the capabilities of the sups to build an SSO pair this for a bug present in 12.2SRx but I see you have 12.2(33)SXI2.
Hope to help
