Usage

When ingress filtering is enabled on a port, the VLAN IDs of incoming frames are compared to the port’s egress list. If the received VLAN ID does not match a VLAN ID on the port’s egress list, then the frame is dropped.

Ingress filtering is implemented according to the IEEE 802.1Q standard.

port‐string	(Optional) Displays the frame discard mode for specific port(s). For a
	detailed description of possible port‐string values, refer to “Port String
