ip dhcp snooping server-screen log-buffer entries NUMBER
no ip dhcp snooping server-screen log-buffer entries
Parameters
NUMBER
Default
By default, this value is 32.
Command Mode
Global Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
Use this command to configure the maximum entry number of the log buffer. The DHCP server
screen log buffer keeps tracks of the information of packets that did not pass the screening. The first
packet that violates the check will be sent to the log module and recorded in the server screen log
buffer. The subsequent packets belonging to the same session will not be sent to log module unless
its record in the log buffer is cleared.
If the log buffer is full but more violation events occur, packets will be discarded but the event will not
be sent to the syslog module. If the user specifies a buffer size less than the current entry number,
then the log buffer will automatically be cleared.
Example
This example shows how to change the maximum buffer number to 64.
Switch# configure terminal
Switch(config)# ip dhcp snooping server-screen log-buffer entries 64
Switch(config)#
