Step 16

Run:

x25 queue-length queue-size

The command configures the length of X.25 VC queue.

Step 17

Run:

x25 map { compressedtcp protocol-address | ip protocol-address } * x121-address

X.121-address no-callout

Calls cannot be initiated by this address mapping.

Step 18

Run:

By default, the value of SVC maximum idle time is 0 minute. One address mapping is

associated with only one VC. The number of pre-acknowledged packets is 0.

The X.25 of the SR8000 allows the addition of some additional characteristics, including a
series of optional user facilities stipulated in ITU-T Recommendation X.25 to improve

performance or broaden the application.

This section shows how to configure additional characteristics, including the options in the

x25 map

....... and the

x25 pvc

.............. commands. Select and configure these additional

characteristics according to actual needs, X.25 network structure, and the available services

provided by service providers.
