To change the default time interval between keepalive messages, use the following command:

Displaying Only Configured Interfaces
The following options have been implemented for show [ip | running-config] interfaces commands for (only)
stack-unit interfaces. When the
configured keyword is used, only interfaces that have non-default
configurations are displayed. Dummy stack-unit interfaces (created with the
stack-unit command) are
treated like any other physical interface.
Figure 21-29 shows the possible
show commands that have the configured keyword available.
