S9300&S9300E Terabit Routing Switch
Configuration Guide - Network Management
Applicable Environment
Some faults cannot be located by capturing service packets. The S9300&S9300E can capture
packets sent to the CPU, and send captured packet information to a TFTP or FTP server or save
information in the CF card. You can analyze the packets sent to the CPU to find causes of the
fault. This function improves network maintenance efficiency and reduces maintenance cost.
Pre-configuration Tasks
Before capturing packets sent to the CPU, complete the following tasks:

Data Preparation
To packets sent to the CPU, you need the following data.

Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
capture-packet cpu [ vlan vlan-id | acl acl-number ]
ftp-server-address [ server-port ]
server server-address ] file file-name | terminal } [ time-out time-out-value |
packet-num number | packet-len { length | total-packet } ]
The S9300&S9300E is configured to capture packets sent to the CPU.
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 cpu 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.
