X.25 Status and Configuration
About using the X.25 protocol; configuring X.25 ports; viewing X.25 management, congestion, and
error stats
An FRX or SmartSwitch 1800 port conÞgured to run X.25 as its layer 2 protocol
can connect to an X.25 DTE or an X.25 network. This allows the port to transmit
X.25 trafÞc, as well as IP and IPX trafÞc (encapsulated as per RFC 1356) and SNA
trafÞc. For any FRX or SmartSwitch 1800 physical ports which have been
conÞgured to use X.25 as their layer 2 protocol (that is, those which display a Port
Type of X25), SPMA provides a variety of statistical information.
For each physical port conÞgured to run X.25, one conÞguration window and
three statistical windows are provided:
¥ The X.25 Physical Port ConÞguration window allows you to conÞgure basic
operational parameters related to the X.25 protocol;
¥ X.25 Management Stats provide management information about standard
LAPB command and response frames, displayed via meters;
¥ X.25 Congestion Stats provide information about standard LAPB command
and response frames related to the level of trafÞc present, displayed in meters;
and
¥ The X.25 Errors window provides information about standard LAPB
command and response frames related to error conditions, also displayed in
meters.
These windows and their functions are described in the following sections.
TIP
The statistical windows display their information via the SPMA Meters application; for
more information on how to manipulate and conÞgure these meters, see the SPMA Tools
Guide
