Displaying SONET Port Status Information
To display status information for the SONET ports, use the following command:
show sonet {<portlist>} {detail}
You can use the optional portlist parameter to narrow the range of status information
the command displays; otherwise, the command displays the status information for all
ports.
By default, the command displays a summary of status information for the specified
ports. You can use the optional
detail keyword to display detailed status information
for the specified ports.
The summary of status information includes the following information for each port:
• Values of all port configuration parameters
• Port state
• Any active events
The detailed status information includes the summary information plus any SONET
statistics (listed and described in Table 3-3).
