RAD Data comm IPmux-11 - Manual (Page 30)

Chapter 1 Introduction Installation and Operation Manual
1-16 Functional Description IPmux-11 Ver. 2.00
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 1-5 lists 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
ARP Not performed
Not performed, even if it is one of
the IPs that is configured for the
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 1-6 lists 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
Telnet
Ping initiated by IPmux-11 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.
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.
