Debug Packet Dump

The hiD 6615 S223/S323 provides network debugging function to prevent system over-
head for unknown packet inflow. Monitoring process checks CPU load per 5 seconds. If
there is more traffic than threshold, user can capture packets using TCP Dump and save
it to file. User can download the dump file with the name of file-number.dump after FP
connection to the system. Verify the dumped packet contents with a packet analyze
promgram.
To debug packet dump, use the following command.
Command
debug packet log
VALUE TIME [1-10]
no debug packet log
Basically, user can save current configuration with write memory command. However,
the dump file is not saved.

Displaying the usage of the packet routing table

The packet routing based on host uses L3 table as it's memory. It searches the informa-
tion of destination addess in L3 table to get the Nexthop information and transmits pack-
ets through Rewriting process.
If it does not find the information of destination in L3 table, it refers to CPU routing table
and records Nexthop information in L3 table and then transmits the packets through Re-
writing process. hiD 6615 provides 4k of L3 table.
The packet routing based on network complements the ineffectual process of recording
with packet unit.
hiD 6615 uses LPT table as it's memory and it provides 16k of LPM table.
To show the usage of L3 table, LPM table or interface used in packet routing, use the fol-
lowing command.
