ip dhcp snooping information option

Use this command to globally allow DHCP packets with relay option 82 on the
un-trusted interface. Use the no form of the command to not allow the packets
with relay option 82.

ip dhcp snooping information option allow-untrusted

no ip dhcp snooping information option allow-untrusted

Syntax

None

Default

Not allow

Command Mode

Global configuration

Usage Guideline

The DHCP snooping function validates the DHCP packets when it arrives at the
port on the VLAN that is enabled for DHCP snooping. By default, the validation
process will drop the packet If gateway address!=0 or option 82 is present.

Use the ip dhcp snooping information option

allow-untrusted

command to allow

the packet with relay option 82 arriving at the un-trusted interface.
