Usage Guidelines

DHCP Discover/Request/Release/Decline/Inform packets received on the switch without giaddr but containing Option 82 are dropped by default. To allow these packets on the switch, PICOS supports Option 82 trust all function:

If trust all is enabled, such packets will be processed according to the configuration of the Option 82 policy.
If trust all is disabled, then drop the packets.

This command is useful if there is a switch in between the client and the DHCP snooping device that may insert Option 82. Use this command to ensure that these packets do not get dropped.

Example

Enable Option 82 trust-all function.
