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.
Example
The following command sets the default packet capture values to debug a wireless WEP station doing VPN. Once
these default settings are defined, you can use the
packet-capture command to enable packet capturing with these
values. 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

Use the show packet-capture command to show the current action and the default values.
