Description
Click the Enabled or Disabled button to enable or disable the function which will record logs
and send traps when the switch detects the illegal DHCP server packets.
The DHCP server filtering function filters any illegal DHCP server packets. The DHCP server
who sends the illegal packets will be logged. This command is used to suppress the logging
of DHCP servers who continue to send illegal DHCP packets. The same illegal DHCP server
IP address that is detected will be logged only once regardless of how many illegal packets
are sent. The log can be suppressed by 1 minute, 5 minutes or 30 minutes. The default
value is 5 minutes.
A consecutive group of ports may be configured starting with the selected port.
Choose Enabled to enable the DHCP server or Disabled to disable. The default is Disabled.
