37. You can use "tab" to complete the command that you are typing.
38. SHOW command is extensively used for seeing the status and
configuration information of the router.
Some of the frequently used commands are:
1.
SHOW RUNNING-CONFIGURATION -This command displays the router's
active configuration file, passwords, system name, and interface
settings, interfaces IP addresses etc.
2.
SHOW INTERFACE - Shows status and configuration information of the
local interfaces. The first line says something like “TokenRing1 is
up, line protocol is up”. The first part “TokenRing1 is up”
describes the physical layer components such as electrical cabling
and signaling are OK. The second part “line protocol is up” means
that the router is detecting keep-alive messages. The router may be
put into administratively down status, at which point the line would
read, “TokenRing1 is administratively down, line protocol is down.”
3.
SHOW INTERFACE SERIAL 0 - Shows the serial 0 configuration.
4.
SHOW INTERFACES - Displays statistics for all interfaces configured
on the switch.
5.
SHOW PROCESS - Displays a router’s CPU utilization.
6.
SHOW CONFIG - Displays information on the startup configuration.
7.
SHOW VERSION - Displays information about the system hardware
(RAM/ROM), software version, names of configuration files, and
boot-images. This command will also show the current configuration
register value.
