Packet Type	VLAN Support
Management	As configured for the manager
TDM over IP	As configured for the connection
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
Telnet
Ping initiated by us
