I have been told by Tivoli that there was a bug if one was using pre 11.2
Cisco IOS. Does your APAR below apply to post 11.2 IOS as well as pre? We
are using 11.2(12), so I thought perhaps this problem was taken care of?
Perhaps there was another separate issue with the pre 11.2 IOS? It
definitely would be useful for us to be able to get color status in the NV
GUI for frame-relay subinterfaces, and we thought NV may be able to provide
this with the discovery of the "0.0.0.0" interfaces on our frame-relay
routers. It would appear that perhaps Tivoli was trying to add this
capabilty - or this just wishful thinking? Thanks,
