Tip:
To reduce the size of the capture file, use any combination of the following
methods:
- Use the
capture interface
command to capture only from a specific
interface.
- Use the
capture max-frame-size
to capture only the first N octets of each
frame. This is valuable since it is usually the packets headers that contain the
interesting information.
- Use capture lists to select specific traffic.
Starting the packet sniffing service
Once you have defined and applied the packet capture lists, use the
capture start
command in general context to instruct the packet sniffing service to start capturing packets.
Note:
Note:
The capture start command resets the buffer before starting the sniffer.
Note:
Note:
You must apply a capture list using the
capture filter-group
command in
order for the capture list to be active. If you do not use the
capture
filter-group
command, the packet sniffing service captures all packets.
If packet sniffing has been enabled by the administrator, the following appears:
If packet sniffing has not been enabled by the administrator, the following appears:
Capturing decrypted IPSec VPN packets
IPSec VPN packets are encrypted packets. The contents of encrypted packets cannot be
viewed when captured. However, you can use the
capture ipsec
command to specify that
IPSec VPN packets, handled by the internal VPN gateway process, should be captured in plain
text format.
