Configuring packet sniffing settings

The packet sniffing service provides several administrative settings you can use to control the
capture functionality. Use the following commands to configure packet sniffing settings. These
commands are all used from general context, and require read/write access.
Use the capture buffer-mode command to specify the type of buffer to use. The
●
available parameters are:
cyclic. Circular buffer that overwrites the oldest records when it is filled up. Use a cyclic
●
buffer to store the most recent history of packet activity.
non-cyclic. Linear buffer that is used until it is filled up
●
For example:
G350-001(super)# capture buffer-mode cyclic
Done!
G350-001(super)#
Use the capture buffer-size command to specify the maximum size of the capture
●
buffer. Available values are 56 to 10000 kb. The default value is 1000. To activate the
change in buffer size, you must run copy running-config startup-config, and
reboot the G250/G350. For example:
G350-001(super)# capture buffer-size 2000
To change capture buffer size, copy the running
configuration to the start-up configuration file, and reset the device.
G350-001(super)# copy running-config startup-config
Beginning copy operation .................... Done!
G350-001(super)#
Use the capture max-frame-size command to specify the maximum number of bytes
●
captured for each packet. This is useful, since in most cases, the packet headers contain
the relevant information. Available values are 14 to 4096. The default value is 128. For
example:
G350-001(super)# capture max-frame-size 4000
This command will clear the capture buffer
- do you want to continue (Y/N)? y
Done!
G350-001(super)#
Note:
When you change the maximum frame size, the G250/G350 clears the capture
Note:
buffer.
