Answer to Ping

If the IPmux-1/1E received the packet with VLAN tagging: the

 

IPmux-1/1E replies with the same VLAN ID (even if it’s one of

 

IPs that is configured for the manager or for the connection)

 

If the IPmux-1/1E received the packet without VLAN tagging: if

 

it’s one of the IPs that is configured for the manager or for the

 

connection, the IPmux-1/1E replies with the VLAN ID that is in

 

the manager or connection configuration

 

 

ARP initiated by us

No VLAN value unless it is to one of the managers or the

 

connection’s IP address
