Several special tools are available to you for use with X.25 network connections. X25CHECK allows you to verify connectivity between two nodes on an X.25 network. X25STAT allows you to monitor the status and statistics for X.25 NIs.

You can run both X25CHECK and X25STAT standalone or from within NETTOOL. Running them from NETTOOL allows you to access help information about the tools. See Chapter 6 "Using NETTOOL" for instructions on running these programs from within NETTOOL.

Verify X.25 Connections

Use X25CHECK to create connections to remote X.25 nodes and verify their response. X25CHECK/X25SERVR is actually a pair of programs. X25CHECK runs on the local node which X25SERVR runs on the remote node. The two work together to diagnose conditions between the nodes.

X25CHECK runs at level 3 on the local node. It tries to establish a virtual circuit with the remote node. After the virtual circuit is established, X25CHECK sends the same message to the remote node five times. The program then measures the time period between sending the message and receiving a response from the remote node.

See Chapter 6 "Using NETTOOL" for instructions on running X25CHECK.

Monitor X.25 Status

Use X25STAT to monitor status and statistics for X.25 connections. The program will display the contents of the internal X.25 tables, including:

  • Global information that is relevant to all connections.

  • Socket table information used for level 3 access.

  • Connection table information.

  • Facilities table information.

  • Path table information.

X25STAT displays the information only once. If you want to update the information display you must run the tool again.
