Overview Use this command to enable DHCP Relay Agent Option 82 information reception
on untrusted ports. When this is enabled, the switch accepts incoming DHCP
packets that contain DHCP Relay Agent Option 82 information on untrusted ports.
Use the no variant of this command to disable DHCP Relay Agent Option 82
information reception on untrusted ports.

Syntax
no ip dhcp snooping agent-option allow-untrusted
Default Disabled
Mode Global Configuration
Usage If the switch is connected via untrusted ports to edge switches that insert DHCP
Relay Agent Option 82 information into DHCP packets, you may need to allow
these DHCP packets through the untrusted ports, by using this command.
When this is disabled (default), the switch treats incoming DHCP packets on
untrusted ports that contain DHCP Relay Agent Option 82 information as DHCP
snooping violations: it drops them and applies any violation action specified by the
ip dhcp snooping violation
dropped; to display these statistics, use the
command.
Example To enable DHCP snooping Option 82 information reception on untrusted ports,
use the commands:
awplus#
awplus(config)#
