Command Line
Processing
Commands are not case sensitive. You can abbreviate commands and parameters
as long as they contain enough letters to differentiate them from any other
currently available commands or parameters. You can use the Tab key to complete
partial commands, or enter a partial command followed by the “?” character to
display a list of possible matches. You can also use the following editing keystrokes
for command-line processing:
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.
Console#configure
Console(config)#ip igmp snooping vlan 1 mrouter ethernet 1/11
Console(config)#end
Console#show ip igmp snooping mrouter
VLAN M'cast Router Ports Type
