I am working with Cisco Nexus 3000 switch. I was under the assumption that a switch will always have a single MAC address but when I ran the following command, it displayed two different MAC addresses though only the first two bytes were different.
show interface ethernet 1/17 mac-address Output: MAC-Address Burn-in-Mac-Address ab:cd:ef:gh:ij:12 ab:cd:ef:gh:ij:78
Each interface on the switch has a different MAC. Can someone explain to me the importance of this? When does the common MAC address and interface specific addresses be used?
