Description: This object indicates whether the DHCP snooping allows the DHCP request packets with relay option 82 on the untrusted interface.
What is dDhcpSnpOption82AllowUntrust?
When enabled, DHCP snooping accepts DHCP request packets that already carry relay agent Option 82 information even when they arrive on an untrusted port, which is normally rejected as a spoofing risk.
