Chapter 4 Troubleshooting the IGX
Troubleshooting an IGX Node
Note Cards with an “F” status (nonterminal failure) are activated only when necessary (for example, when
there is no card of that type available). Cards with a failed status are never activated.
To display cards, issue the dspcds command. The dspcds command cannot be included in a job. Refer
to the Cisco WAN Switching Command Reference for more information.
User-Initiated Tests
Several user commands help you test the node status. The CLI commands are:
• tstcon—For voice connections
• tstcon—For data connections
• tstport—For data and Frame Relay ports
For details on these commands, see the Cisco WAN Switching Command Reference.
