Configuring Frame Relay
7-15
1
If rate control will not be used, configure the
Committed Information Rate
(CIR) to
match the line speed on the port. Otherwise, the DE-bit will be set on all received 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 G roup Number
is a value other than
0
.
6
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. (Protocol configuration is described in
Chapter 5
.)
Physical Port Interface
is determined by the Line Interface Card(s) and attached cables. The RLP record iden-
tifies the LIC, and only the valid interfaces will be displayed on the Port screen,
among:
RS-232, V.35, RS-449
, and
X.21
.
(RS-449 and X.21 i
nterfaces are valid if the LIC
is RS-422.)
Blocked Port Flag
will cause the port to be enabled (
N
) or disabled (
Y
) at node IPL. The port will remain
in that state until this parameter is changed or an on-line enable (
[B], [B], [C]
from the
Main Menu) or disable (
[B], [B], [A]
from the Main Menu) is performed.
If set to
Y
, no backup DLCIs on this port will be used (even if the port is enabled via
on-line port enable).
