Dear Experts,
We have 6506 Core switch with 2 SUP card. in Last week one was become faulty and now I have replaced it with new one.
During the time other SUP is in designated mode and working ok. NW is UP. System is configured with HSRP.
Now the steps I had taken for replaceing it are :
1. Plug the new SUP card in slot.
2. Console it and configured High Avialability + Config Sync.
3. In a second the whole cofiguration was coppied in new Card.
But the the problem i found that the HSRP priority was not seen in new Card ..Rest of the config is there in new Card ?
Why this happen and how to resolve it ...
pls suggest the steps....or docs...

Hello Dipesh,
if you use SSO for redundancy the following applies to you:
The Hot Standby Routing Protocol (HSRP) is not SSO-aware, meaning state information is not maintained between the active and standby supervisor engine during normal operation. HSRP and SSO can coexist but both features work independently. Traffic that relies on HSRP may switch to the HSRP standby in the event of a supervisor switchover.
see
if HSRP is not SSO aware from the point of view of HSRP the two supervisors are competitors for the role of active router.
From this should come the fact that standby priority command is not copied in new card
Hope to help
