VLAN and interface MAC assignments. " Can VLAN mac addresses be modified?"
My question should be simple and direct, unfortunately I have not found a satisfactory answer.
Question: When I do an arp -v from the cli, I notice that one of my VLAN mac address assignments should be on a different interface listed. This is confusing and my customer would like the interfaces and mac addresses to line up.
To demonstrate the issue:
1.1 is 00:23:e9:67:97:02 net interface 1.1 VLAN INSIDE 550 mac-address 10.240.102.10 1.2 is 00:23:e9:67:97:03 net interface 1.2 VLAN OUTSIDE 547 mac-address 10.240.105.5
"snippet from arp -v"
00:23:e9:67:97:03 net interface 1.2 mac-address 00:23:e9:67:97:03 net vlan INSIDE mac-true <--- shows the mac address of the INSIDE VLAN where it should be on the OUTSIDE VLAN on 1.1
I have read SOL14513. To me the above leads to administrative confusion

Is this box hardware or a VE? If the latter, which hypervisor?

Following up to my own post, the MACs indicate this is hardware.
Unless you're using MAC masquerade, there is a static relationship between the interfaces (1.1, 1.2) and the MAC addresses. It also appears that both your inside and outside VLANs are tagged - are you dedicating one interface to each VLAN? If so, this should be as simple as making sure that your VLANs are defined as tagged on one, and only one, interface. Network>>VLANs
What version of TMOS is this?
not a ve...
TMOS 11.2.1
- dirtycacheSo were you able to sort it out given that each physical interface has MAC address, and that you want to put your VLANs untagged on the interface which has the MAC you want, or are you still having trouble?
