I have a design where I need to change the mac address on an SVI interface on a Nexus 5600 switch. As you can see below, it is possible on the Nexus 9K but not the 5K. Anyone know why and if there is another way to do it?
!!! Nexus 9k Switch - code 7.0(3)I4(1)
Nexus9k(config)# feature interface-vlan Nexus9k(config)# int vlan 1 Nexus9k(config-if)# mac-address ? E.E.E MAC address (Option 1) EE-EE-EE-EE-EE-EE MAC address (Option 2) EE:EE:EE:EE:EE:EE MAC address (Option 3) EEEE.EEEE.EEEE MAC address (Option 4)
!!! Nexus 5600 Switch - code 7.1(4)N1(1)
Nexus5k(config)# int vlan 1 Nexus5k(config-if)# ? bandwidth Set bandwidth informational parameter carrier-delay Specify delay for interface transitions default Undo a command delay Specify interface throughput delay description Interface specific description hsrp HSRP interface configuration commands inherit Inherit a port-profile ip Configure IP features ipv6 Configure IPv6 features management Allow in-band management access to VLAN Interface IP address mtu Set the interface Maximum Transmission Unit (MTU) no Negate a command or set its defaults rate-limit Set packet per second rate limit shutdown Enable/disable an interface site-of-origin Site of Origin snmp Modify SNMP interface parameters vrf Configure VRF parameters end Go to exec mode exit Exit from command interpreter pop Pop mode from stack or restore from name push Push current mode to stack or save it under name where Shows the cli context you are in
Did you, or someone else find a solution for that problem?
Currenty I have the same problem, when interconnecting two VRFs on the same chassis, both sides of the transferlink have the same MAC address, and therefore communication between those VRFs is not possible.
