Packet Type VLAN Support
Management As configured for the manager
TDM over IP As configured for the connection
Answer to Ping If the IPmux-11 received the packet with VLAN tagging: the
IPmux-11 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-11 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-11 replies with the VLAN ID that is in the
manager or connection configuration
ARP initiated by us
Telnet
Ping initiated by us
No VLAN value unless it is to one of the managers or the
connection’s IP address
Ethernet Ports
The Ethernet user ports allow a user to aggregate both TDMoIP traffic and his
private network LAN traffic to a single Ethernet network connection without
requiring an access switch. This is a cost-effective solution for MTU or small-office
applications. A rate limiter to restrict user port traffic is supported.
