Additional Information

Click an interface name to see more information about the interface.

Channelized interfaces appear as two interfaces, which can both be monitored. For example:

■If ce1-3/0/0is configured as a clear channel, you can monitor ce1-3/0/0and e1-3/0/0.

■If ct1-3/0/1is channelized, you can monitor ct1-3/0/1and ds-3/0/1:1.

The operational state is the physical state of the interface. If the interface is physically operational, even if it is not configured, the operational state is Up. An operational state of Down indicates a problem with the physical interface.
