packet-capture
packet-capture [other {disable | enable}] [sysmsg {all | disable | <opcodes>]
[tcp {all | disable | <ports>}] [udp {all | disable | <ports>]
]
Description
Use this command to enable or disable packet capturing and set packet capturing options for a single packet
capture session.
Syntax
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:
z Station up/down: sysmsg opcode 30
z WEP key plumbing: sysmsg opcode 29
z DHCP: sysmsg opcode 90
z IKE: UDP port 500 and 4500
z Layer 2 Tunneling Protocol (L2TP): UDP port 1701
(host) #packet-capture sysmsg 30,29,90 udp 500,4500,1701,1812,1645
