match occurs. If this default entry is not present, the unit falls back to using IARP to determine the
protocols to use with that particular virtual circuit. If a static maintenance protocol is used, at least one
DLCI mapping must be specified.
L2 PROTOCOL (T1 TDM–T1–FRE) > CONFIG > DLCI MAPPING > NUM
Displays the index number in the DLCI mapping table.
L2 PROTOCOL (T1 TDM–T1–FRE) > CONFIG > DLCI MAPPING > ACTIVE
When this parameter is set to YES (def), the mapping is used to determine the protocols used. If set to NO,
the unit will ignore the virtual circuit with this DLCI.
L2 PROTOCOL (T1 TDM–T1–FRE) > CONFIG > DLCI MAPPING INTERFACE
Shows the user the physical and logical port associated with each DLCI. This is a read-only field.
L2 PROTOCOL (T1 TDM–T1–FRE) > CONFIG > DLCI MAPPING > DLCI
This DLCI (Data Link Connection Identifier) number identifies the virtual circuit being configured.
L2 PROTOCOL (T1 TDM–T1–FRE) > CONFIG > DLCI MAPPING > MODE
The mode identifies how the data will be forwarded. The choices are:
L2 PROTOCOL (T1 TDM–T1–FRE) > CONFIG > DLCI MAPPING > BECN TIMEOUT (MSEC)
This value is expressed in milliseconds and represents the amount of time the unit will stop transmitting
over a PVC which received a packet with the BECN bit set. Range is
50-5000 msec; the default is
50 MILLLISECONDS.
L2 PROTOCOL (T1 TDM–T1–FRE) > STATUS
View the L2 protocol status for the T1 interface using the Frame Relay protocol.
To insert a new profile, press the I key when over the Num column. A new inserted profile
will always be set up with the default parameters. To copy parameters from an old profile
to this newly inserted profile, use the copy (C) and paste (P) keys. Entire configuration
trees can be copied with this method.
To delete an unused profile, use the D key when the cursor is over the number in the Num
column. Once deleted, the profile is gone permanently.
ROUTE IP (def) All IP data for this DLCI will be routed.
B
RIDGE ALL All data for this DLCI will be bridged.
R
OUTE UIP/BRIDGE OTHER All IP data will be routed. All other data will be bridged.
