Platform
description This command is supported on all switches.

Use this command to set rate limit of receiving DHCP packets on the interface. The no form of this
command removes the setting.

Parameter
description
Parameter Description
rate-value Rate of receiving DHCP packets (pps).
Default
No rate limit.
Command
mode Interface configuration mode.
Usage
guidelines
This function takes effect for all the interfaces of the VLAN controlled by the
DHCP Snooping, including trust interface.
For some CPP-enabled products, CPP will restrict the rate of DHCP packets
by hardware. CCP-based rate limit takes precedence over DHCP
Snooping-based rate limit. For CPP, please refer to specific chapters.
You can view the rate limit setting on the corresponding interface by show ip
dhcp snooping command.
Note that S86 does not support rate limit of DHCP packets on an interface.
Examples
The following example sets rate limit of port 1 as 100:
Ruijie# configure terminal
Ruijie(config)# interface fastEthernet 0/1
Ruijie(config-if)# ip dhcp snooping limit rate 100
Ruijie(config-if)# end
Ruijie# show ip dhcp snooping
