disable to bypass the all setting. All CLI ports are always skipped.

sysmsg
Enable or disable internal messaging packets. Disabled
tcp ports
Enable or disable TCP packet capturing. Specify up to ten comma-
separated ports to capture; use all to sniff all TCP ports; use disable
to bypass the all setting. All CLI ports are always skipped.

Usage Guidelines
This command applies to control path packets; not datapath packets. Packets can be retrieved through the tar log
command; look for the filter.pcap file. This command activates packet capture options on the current switch. They
are not saved and applied across switches.
If you do want to enable a packet capture session without setting values that can be saved and used for another
session, use the command packet-capture. The related command packet-capture-defaults lets you define a set of
packet capture options that will run every time you enable the packet capture feature.
Example
The following command enables packet capturing for debugging a wireless WEP station doing VPN. This example
uses the following parameters and values:
l Station up/down: sysmsg opcode 30
l WEP key plumbing: sysmsg opcode 29
l DHCP: sysmsg opcode 90
l IKE: UDP port 500 and 4500
l Layer 2 Tunneling Protocol (L2TP): UDP port 1701
