Capture packets (like linux tcpdump/ Solaris snoop)

Start a Capture

\# capture [name] interface [interface name] match [protical (ip/icmp/tcp/udp)] host [source host (x.x.x.x/any)] [Dest host (x.x.x.x/any)]

Stop the capture but keep the data

\# no capture [name] interface [interface name]

List Caputres

\# show capture [name]

Delete the capture

\# no capture [name]

Example

# capture SH interface extern match ip host 10.10.10.10 any

# show capt
capture SH type raw-data [Capturing - 14486 bytes] 
  match ip host 10.10.10.10 any 

# show capture SH
