2.15.3. Debug Commands
Debug command provides a function enables an administrator to see any fault in network or
equipment settings by decoding a specific packet passing through the router equipment. Debug
command can be used in Exec mode.
The caution for using Debug command is that the system takes a lot of resource. Therefore, it is
recommended to use Debug command for the necessary portion at the minimum range. Turn off
the debug functions that are not in use because they can degrade performance of the entire
system.
For debugging IP or TCP packet especially from Telnet Virtual Terminal, debugging
function can operate continuously and recursively by debugging TCP/IP packets
continuously and displaying debugging message. In this case performance of the router
can be dropped definitely.
To avoid this case for debugging IP or TCP packets from Telnet Virtual Terminal, it is
strongly recommended to use access-list and remove such debugging function for TCP/IP
packets of the Telnet terminal from the entire debugging function.
Debug command can be used in exec mode and the Syntax is listed as to follow:
z debug {option} : Enable debugging.
z no debug {option} : Disable debugging
The followings are the debugging related command options:
z ppp {chap/error/negotiation/packet }
1. Display as to decode PPP settings or operational status
2. The followings are the details of the option
1) chap: show exchange of information during chap setup process by decoding
2) error: show error information from PPP process by decoding
3) negotiation: show the PPP Link Negotiation by decoding
4) packet: show PPP packet by decoding
