Issue Description

Can a Router support DHCP Snooping Function Without Using a LAN Card?


No, DHCP snooping function can only be supported by the LAN card.

To restrict source MAC addresses without a LAN card installed, the router can use Layer 2 ACL. However, Layer 2 ACL is not a replacement for DHCP snooping.
