When you connecting switches with FC ports (fiber channel connection for SAN environment)
you can’t use the ‘show cdp neighbors’ command to view connected switches
but you can use ”show topology” command
ucs-lab-A(nxos)# show topology FC Topology for VSAN 91 : -------------------------------------------------------------------------------- Interface Peer Domain Peer Interface Peer IP Address -------------------------------------------------------------------------------- fc2/1 0x33(51) fc1/43 10.100.215.11 FC Topology for VSAN 92 : -------------------------------------------------------------------------------- Interface Peer Domain Peer Interface Peer IP Address -------------------------------------------------------------------------------- fc2/2 0x1d(29) fc1/44 10.100.215.11
