i had installed 2 NAM modules on a Cisco 6509 switches in A VSS environment.Initially both NAMs on the two VSS switches were working properly but after some time one NAM become inaccessible in that i couldnt ping it from the default gateway neither could i open its GUI.I tried to troubleshoot by resetting this NAM module to its factory settings and configuring its network parameters again but still it couldnt work.so am wondering what could be the problem since everything seems ok. Please anyone with an idea on what am supposed to do?
Are you saying you can ping the active NAM, but not the standby? I did notice the NAM is switch 1 has the proper management port config, but this is not present for the NAM in switch 2. You would need to add:
analysis switch 2 module 3 management-port access-vlan 411
It appears you had this command in the switch at one point, but it must have been removed.
