Quidway S2700 Series Ethernet Switches
Configuration Guide - IP Service
When an IP, TCP, UDP, RAWIP, or RAWLINK fault occurs, run the following debugging
commands in the user view to locate the fault.
For details on debugging commands, see the Quidway S2700 Series Ethernet Switches
Debugging Reference.

3.5 Configuration Examples
This section provides several configuration examples of IP performance.
3.5.1 Example for Disabling the Sending of ICMP Host Unreachable
Packets
This section provides a configuration example of disabling the sending of ICMP host
unreachable packets.
Networking Requirements
As shown in
and Switch C are required and these devices are connected through their Ethernet interfaces.
Issue 01 (2011-07-15)
Run the debugging ip packet [ error ] [ acl acl-number ] [ verbose ] command in the user
view to debug IP packets.
Run the debugging ip icmp [ verbose ] command in the user view to debug ICMP packets.
Run the debugging udp packet [ src-ip src-address ] [ src-port src-port ] [ dest-ip dest-
address ] [ dest-port dest-port ] or debugging udp packet [ task-id task-id ] [ socket-id
socket-id ] command in the user view to debug UDP packets.
Run the debugging tcp packet [ src-ip src-address ] [ src-port src-port ] [ dest-ip dest-
address ] [ dest-port dest-port ] [ flag flag-number ] or debugging tcp packet [ task-id
task-id ] [ socket-id socket-id ] [ flag flag-number ] command in the user view to debug
UDP packets.
Run the debugging tcp event [ local-ip local-address ] [ local-port local-port ] [ remote-
ip remote-address ] [ remote-port remote-port ] or debugging tcp event [ task-id task-
id ] [ socket-id socket-id ] command in the user view to debug TCP events.
Run the debugging tcp md5 [ src-ip src-address ] [ src-port src-port ] [ dest-ip dest-
address ] [ dest-port dest-port ] or debugging tcp md5 [ task-id task-id ] [ socket-id
socket-id ] command in the user view to debug TCP Message Digest Algorithm 5 (MD5)
authentication.
Run the debugging rawip packet [ src-ip src-address ] [ dest-ip dest-address ]
[ protocol protocol-number ] [ verbose verbose-number ] or debugging rawip packet
[ task-id task-id ] [ socket-id socket-id ] [ verbose verbose-number ] command in the user
view to debug RAWIP packets.
Run the debugging rawlink packet [ src-mac src-mac ] [ dest-mac dest-mac ]
[ verbose verbose-number ] or debugging rawlink packet [ task-id task-id ] [ socket-id
socket-id ] [ verbose verbose-number ] command in the user view to debug RAWLINK
packets.
