Description

Parameters
rate
: Maximum rate of DHCP traffic in pps. This argument ranges from 10 to 150.
Description
Use the
dhcp rate-limit
command to configure the maximum rate of DHCP traffic for the port. When
the number of DHCP packets received on the port per second exceeds the specified threshold, the
switch will discard the exceeding DHCP packets.
Use the
undo dhcp rate-limit
command to restore the default.
By default, after the DHCP traffic limit is enabled, the maximum rate of DHCP traffic is 15 pps.
