I'm tracing the mac address to find what port it's on and I see it on our Cisco Nexus 7K device with the output below:

Nexus7010# sh mac address-table | inc 65a0.e845.3151
G     -    65a0.e845.3151    static       -       F    F  sup-eth1(R)

G 948      65a0.e845.3151    static       -       F    F  sup-eth1(R)

I don't know what this means, the vlan the the device is on is vlan 54, can someone explain this to me?

thank you,

What NX-OS version are you running?
What supervisor is installed?

Please issue the command "show mac address-table 65a0.e845.3151" and post the output.

Does your nexus have a L3 interface on all those vlans?

Do:

show int vlan 948 | i Hardware
show int vlan 95 | i Hardware

You will probably find that this is the mac address the Nexus is using for its L3 addresses.

Additionally:

show int mac-address

should show that mac address is the mac address on just about all ports, both physical and svi.
