6.4.3 Debugging IP Performance

Context
Debugging affects the performance of the system. So, after debugging, run the undo debugging

When an IP, TCP, UDP, RAWIP, or RAWLINK fault occurs, run the following debugging
commands in the user view to locate the fault.

Issue 01 (2012-03-15)
Run the display fib [ vpn-instance vpn-instance-name ] interface interface-type interface-
number command to check information about the FIB entries with the outgoing interface
as a specified interface.
Run the display fib [ vpn-instance vpn-instance-name ] ip-prefix prefix-name
[ verbose ] command to check information about the FIB entries that match a specified IP
prefix list.
Run the display fib [ slot-id ][ vpn-instance vpn-instance-name ] destination-address1
[ destination-mask1 ] [ longer ] [ verbose ] command to check information about the FIB
entries that match destination IP addresses in a specified range.
Run the display fib [ vpn-instance vpn-instance-name ] next-hop ip-address command
to check information about the FIB entries that match the specified next hop address.
Run the display fib [ slot-id ] [ vpn-instance vpn-instance-name ] statistics command to
check the total number of FIB entries.
CAUTION
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.
