show and debug Commands
http://vnexperts.net
ICND1 v1.01-11
Considerations When Using debug
Commands
May generate output in a variety of formats that may not identify
the problem
Require high overhead, possibly disrupting network device
operation
Useful for obtaining information about network traffic and router
status

Commands Related to debug
RouteX(config)#
service timestamps debug datetime msec
Adds a time stamp to a debug or log message
RouteX#
show processes
Displays the CPU utilization for each process
RouteX#
no debug all
Disables all debug commands
RouteX#
terminal monitor
Displays debug output on your current vty session

Summary
The Cisco IFS feature provides a single interface to all the file
systems (NVRAM, RAM, TFTP, flash) that a router uses.
As a network grows, storage of the Cisco IOS Software and
configuration files on a central server enables control of the
number and revision level of software images and configuration
files that must be maintained.
Having proper backup of the current device configuration stored in
a TFTP server can help reduce device downtime.

Summary (Cont.)
The Cisco IOS Software copy commands can be used to move
configurations from one component or device to another, such as
RAM, NVRAM, or a file server.
The show and debug commands are built-in tools for
troubleshooting. The show command is used to display static
information, while the debug command is used to display
dynamic data.
