MAC addresses used for VLANs on 11506

The MAC addresses used for each virtual IP address on each VLAN is different (the last two digits refer to the VLAN ID.)

Is there any command to to view the MAC addresses allocated for each VLAN on Master and backup boxes?

Re: MAC addresses used for VLANs on 11506

if you have configured redundancy, the mac address is a special one that is shared by both master and backup.

The last byte is not the vlan id but the virtual router id which in your case seems to be the same as the vlan id.

The first bytes are always the same

0000.5e00.01XX

The physical interface mac address is different.

You can see it with the command 'ip if' from llama/debug mode.

Regards,

Gilles.
