Display Only Configured Interfaces
The following options have been implemented for show [ip | running-config] interfaces commands for
(only) linecard interfaces. When the
configured keyword is used, only interfaces that have non-default
configurations are displayed. Dummy linecard interfaces (created with the
linecard command) are treated
like any other physical interface.
Figure 20-37
lists the possible show commands that have the configured keyword available:
