port-channel-253 is port-channel going to nexus 7K's
************************************************************************************************************************
Question:
- I am going to fix the VTP by changing VTP mode on primary N5K matching to secondary ...On secondary i have VTP as transparent.
- My question is " if i change VTP mode on primary does my spanning tree root changes ??"
- How can i make spanning tree root on N5K primary pointing to port-channel-253 instead of port-channel 53
