Showing Status
Information
There are various “show” commands which display configuration settings or the
status of specified processes. Many of these commands will not display any
information unless the switch is properly configured, and in some cases the
interface to which a command applies is up.
For example, if a static router port is configured, the corresponding show command
will not display any information unless IGMP snooping is enabled, and the link for
the static router port is up.
