You can also configure the source MAC address of the loop-detecting packet. Normally
the system’s MAC address will be the source MAC address of the loop-detecting packet,
but if needed, Locally Administered Address (LAA) can be the address as well.
If the switch is configured to use LAA as the source MAC address of the loop-detecting
packet, the second bit of first byte of the packet will be set to 1. For example, if the
switch’s MAC address is 00:d0:cb:00:00:01, the source MAC address will be changed to
02:d0:cb:00:00:01.
To select the source MAC address type of the loop-detecting packet, use the following
command.
Command Mode Description
loop-detect srcmac laa
Uses LAA as the source MAC address of the loop-
detecting packet.
loop-detect srcmac system
Bridge
Uses the system’s MAC address as the source MAC
address of the loop-detecting packet. (default)
If you would like to change the source MAC address of the loop-detecting packet, you
should disable the loop detection first using the
loop-detect disable command.
To display a current configuration of the loop detection, use the following command.
