Using show commands for operational analysis
show spx connections command provides information on point-to-point connections to help analyze the Campus
Fabric domain. The
show spx-mon command helps to diagnose and correct a variety of issues.
The
show stack connection command can be used to show stack cable connections. Likewise, in a Campus Fabric
domain, the
show spx connections command provides comprehensive information on physical connections, which eliminates
the need to trace cables manually in the switch room.
Enter the
show spx connections command in Privileged EXEC mode to display information on point-to-point Campus Fabric
connections.
The following example displays information on six SPX connections that form three two-port LAGs. The port connections for each LAG are provided. Based on the connections displayed, three PE units (17, 18, and 19) are connected to the CB. PE units 17 and 18 form a chain. PE unit 19 is connected directly to the CB and has no downstream units.

Using the
show spx-mon command, you can diagnose a variety of operational issues, including PE configuration
mismatch, image mismatch, excessive SPX port traffic, and numerous PE join problems.
For detailed information on using SPX monitoring capabilities to analyze issues, refer
to
Enabling and using SPX monitoring in this guide.
With spx-mon enabled, enter the
show spx-mon command in Privileged EXEC or global configuration mode to display detailed system
information.
The following example enables spx-mon and displays information on the Campus Fabric configuration. Two PE units are in Ready state, and one PE has reserved configuration only. CLI guidance is given to troubleshoot a potential pe-join issue with the third PE unit.
