Syntax

ip dhcp snooping limit rate

VALUE

no ip dhcp snooping limit rate

Parameters

•

VALUE

—Number of DHCP messages that an interface can receive per

second.

Default Configuration

DHCP snooping rate limiting is disabled.

Command Mode

Interface Configuration mode

User Guidelines

The rate limit normally applies to untrusted interfaces. If you want to configure rate
limiting for trusted interfaces, trusted interfaces may aggregate DHCP traffic on
multiple VLANs (some of which may not be snooped) on the switch, and you will
need to adjust the interface rate limit to a higher value.

If the rate limit is exceeded, the interface is error-disabled. If you enable error
recovery by entering the errdisable recovery cause dhcp-rate-limit Global
Configuration mode command, the interface retries the operation again when all
causes have timed out. If the error recovery function is not enabled, the interface
stays in the error-disabled state until you enter the shutdown and no shutdown
Interface Configuration mode commands.

Example

switchxxxxxx(config)#

interface fa7

switchxxxxxx(config-if)#

ip dhcp snooping limit rate 100

ip dhcp snooping trust

To configure a port as trusted for DHCP snooping purposes, use the ip dhcp
snooping trust Interface Configuration mode command.

To revert to its default setting, use the no form of this command.
