Configuring Frame Relay 7-15
1
If the Committed Information Rate is set to 0 and the Excess Burst Size is set to a value
greater than 0 , the DE (Discard Eligibility) bit will be turned on in all received ( In ) and/
or transmitted ( Out ) frames.
2
CIR = Committed Information Rate. (See first parameter in table.)
3
Applicable only on the initiating node. (See explanation.) If configuring a DLCI that will
be backed up, you must leave this value at
0
until you have configured a backup group.
Then re-enter Port Configuration on this RLP/port/DLCI and specify the desired group.
A value of
0
means that the DLCI will not be backed up; therefore, set the Group to
0
if
the DLCI will be a backup.
4
Set to N for the initiating backup DLCI and Y for the remote backup DLCI.
5
Displayed only if
Backup Group Number
is a value other than
0
.
6
Valid only if the remote node is an FRX6000 or FRM.
7
If set to 65535 , switchback will not occur unless the backup fails.
Port Type
specifies the protocol the port will support. Selecting this parameter will display a list
of valid protocols. An FRX4000 port can be configured as any WAN protocol loaded
in the device. An FRX6000 port can be configured as any WAN protocol configured
on this port's RLP. (
Protocol configuration is described in Chapter 5 .)
Physical Port Interface
must be configured as follows. For reference, port locations are shown on page 6-1
(FRX4000) and page 6-2 (FRX6000).
●
FRX4000 port 0 is always
RS-232
.
●
FRX4000 port 1 is
RS-232
or
DSU
, depending on whether the optional CSU/
DSU card is installed.
●
FRX4000 ports 2 and 3 are determined by the attached cables:
RS-232, V.35, RS-
449
, or
X.21
.
●
FRX4000 ports 4–7 are determined by the expansion Line Interface Card (LIC)
and attached cables. RLP Configuration identifies the LIC, and only the valid
