Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
capture-packet { interface interface-type interface-number | acl acl-number }
[ vlan vlan-id | cvlan cvlan-id ]
[ server-port ] user-name user-name password password | tftp-server server-
address ] file file-name | terminal } [car cir car-value | time-out time-out-value
| packet-num number | packet-len { length | total-packet } ]
The S9300&S9300E is configured to capture service packets.
WAN boards do not support this command.
The packet capture configuration is not saved in the configuration file, and becomes invalid
when packet capture is complete.
The S9300&S9300E can capture only upstream packets and cannot capture downstream packets.
Before using the capture-packet command again, wait until the last command execution is
complete.
The system limits the rate of captured packets. The default rate limit is 64 kbit/s. If the rate of
packets exceeds the limit, some packets may be discarded.
If captured packet information fails to be sent to the TFTP or FTP server, the S9300&S9300E
switch saves captured packet information locally.

10.4 Capturing Packets Sent to the CPU

Before capturing packets sent to the CPU on an S9300&S9300E switch, familiarize yourself
with the applicable environment, complete the pre-configuration tasks, and obtain the data
required for configuration. This can help you complete the configuration task quickly and
accurately.
