ROTOCOL
The Frame Relay maintenance protocol is used on the WAN port. The maintenance protocol is used to
send link status and virtual circuit information between Frame Relay switches and other devices (such as
routers that communicate with them. Possible choices are as follows:
The default value is

REQUENCY
(5-30)
This parameter is the interval that the unit polls the Frame Relay switch using the maintenance protocol
selected. The unit is required to poll the Frame Relay switch periodically to determine whether the link is
active. The value is in seconds and ranges from
5
to
30
seconds with a default of
10

APPING
This menu allows each DLCI to be mapped to a particular Frame Relay maintenance protocol. Each
protocol parameter can be individually configured for each DLCI. By factory default, the DLCI map is
empty.
When empty and a maintenance protocol other than the static is used, the unit will poll the switch to
determine which DLCIs are active. These active DLCIs will attempt to determine the IP addresses on the
other end of the virtual circuit using Inverse ARP (IARP). If there is a response, the network learned will
be added to the router tables and the virtual circuit will be treated as an unnumbered interface. Bridge
connections are made using bridge group 1. When more than one DLCI mapping is listed, the unit will try
to match the DLCIs learned from the Frame Relay switch with the DLCI values in the map. If there is a
match, the protocols specified in the map are used. However, if an active DLCI is not in the list, the unit
looks for an entry that has 0 in the DLCI field. This entry is considered the default entry to use when no

NNEX

This ANSI standard ANSI T1.617-D and is the most commonly used in
the United States.
A
NNEX
A (Q933A)
This is the CCITT European standard, ITU-T Q.933-A.
LMI
This was developed by a vendor consortium and is also known as the
“Consortium” management interface specification. It is still used by some
carriers in the United States.
S
TATIC
(N

S
IG
)
This should be selected when there is no Frame Relay switch in the
circuit. The DLCIs are assigned in the DLCI Mapping and must be the
same for the device it will communicate with.
