RAD Data comm IPmux-11 operation manual Vlan Traffic Behavior, Ethernet Ports

Chapter 1 Introduction Installation and Operation Manual

IPmux-11 transfers fault conditions only if the payload format is configured to V2. The fault conditions are transferred as follows:

•Framed E1 or T1: RDI as RDI, LOS and AIS as AIS

•Unframed E1 or T1: LOS and AIS as AIS.

VLAN Traffic Behavior

Table 1-5lists the IP and VLAN validity checks that are performed with each

Ethernet packet that is received by IPmux-11.

Table 1-5. VLAN Check for Packets that are Received by IPmux-11

Packet Type	Source IP Check	VLAN Check
Management	Performed	Performed
TDM over IP	Performed	Performed
Receiving ping	Not performed	Not performed, even if it is one of
		the IPs that is configured for the
ARP	Not performed
		manager or for the connection

Telnet	Performed only when Telnet access mark is
	from manager

Performed only when Telnet access mark is from manager

Table 1-6lists the IP and VLAN validity checks that are performed with each

Ethernet packet that is sent by IPmux-11.

	Table 1-6. VLAN Check for Packets Sent by IPmux-11
Packet Type	VLAN Support
Management	As configured for the manager
TDM over IP	As configured for the connection
Answer to ping	Packet with VLAN tagging: IPmux-11 replies with the same VLAN ID (even
	if it is s one of IPs configured for the manager or for the connection).
	Packet without VLAN tagging: if it is one of the IPs 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 IPmux-11	No VLAN value unless it is to one of the managers or the connection’s IP
Telnet	address
Ping initiated by IPmux-11

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.

IPmux-11 contains an internal bridge where one of its ports is connected to a TDMoIP interworking function, two external bridge ports is used as the user ports, and the fourth is used as an Ethernet network port.
