246 Serviceability Packet Tracing Commands
remote In the remote capture mode, the captured packets are
redirected in real time to an external PC running the
Wireshark tool for Microsoft Windows. A packet
capture server runs on the switch side and sends the
captured packets via a TCP connection to the
Wireshark tool.
The remote capture can be enabled or disabled using
the CLI. There should be a Windows PC with the
Wireshark tool to display the captured file. When
using the remote capture mode, the switch does not
store any captured data locally on its file system.
You can configure the IP port number for connecting
Wireshark to the switch. The default port number is
2002. If a firewall is installed between the Wireshark
PC and the switch, then these ports must be allowed
to pass through the firewall. You must configure the
firewall to allow the Wireshark PC to initiate TCP
connections to the switch.
If the client successfully connects to the switch, the
CPU packets are sent to the client PC, then
Wireshark receives the packets and displays them.
This continues until the session is terminated by
either end.
Starting a remote capture session automatically
terminates the file capture and line capturing.
line In the capture line mode, the captured packets are
saved into the RAM and can be displayed on the
CLI. Starting a line capture automatically terminates
any remote capture session and capturing into a file.
There is a maximum 128 packets of maximum 128
bytes that can be captured and displayed in line
mode.
