Configuring Frame Relay 8-5
When Changes Take Effect at the Port
When you add a new Port record, it will be written to the database as soon as you enter
the final parameter value. When you modify a parameter in an existing record, the
change will be written to the database immediately.
The change will become effective at the port in one of the following ways:
●
Press [F7] while still in Maintenance operations on the record. This will tempo-
rarily disable the port, then write the change to the software running in the node.
●
Re-IPL the node containing the changed port.
Frame Relay Port Parameters
1
128, 256, 512, 1024, 2048, 4096 . If X.25 logical ports will be configured on this port, do
not configure a size greater than
2048
. If
4096
is specified, additional X.25 and frame
headers can make the frame too large. 2048 will not cause a problem, since larger frames
will simply be split, then re-assembled at the destination.
Physical Interface
is the hardware interface, determined by the associated Line Interface Card (LIC) and
the cable attached to the port's I/O box connector. The LP record identifies the LIC,
and only the valid interfaces will be displayed as choices in the Port record. LICs are
shown in parentheses:
3 = RS-232 (RS-232) 4 = V.25Bis_Dial (RS-232) 5 = V.35 (V.35)
6 = RS-449 (RS-422) 7 = RS-530 (RS-422) 8 = X.21 (RS-422)
