ip dhcp snooping information option allowed-untrusted

The

ip dhcp snooping information option allowed-untrusted

Global Configuration mode command

configures a switch to accept DHCP packets with option-82 information from an untrusted port. Use the

form of this command to configure the switch to drop these packets from an untrusted port.

Syntax

•

ip dhcp snooping information option allowed-untrusted

•

no ip dhcp snooping information option allowed-untrusted

Default Configuration

The default configuration is to discard DHCP packets with option-82 information from an untrusted
port.

Command Mode

Global Configuration mode.

User Guidelines

There are no user guidelines for this command.

Example

The following example configures a switch to accept DHCP packets with option-82 information from an
untrusted port:.

ip dhcp snooping verify

The

ip dhcp snooping verify

Global Configuration mode command configures a switch to verify on an

untrusted port that the source MAC address in a DHCP packet matches the client hardware address.
Use the

form of this command to not verify the MAC addresses.
