5.2.5. Private VLAN Commands
This section describes the commands you use for private VLANs. Private VLANs provides Layer 2 isolation
between ports that share the same broadcast domain. In other words, it allows a VLAN broadcast domain to be
partitioned into smaller point-to-multipoint subdomains. The ports participating in a private VLAN can be
located anywhere in the Layer 2 network.
Ingress Filtering
May be enabled or disabled. When enabled, the frame is discarded if this port is
not a member of the VLAN with which this frame is associated. In a tagged
frame, the VLAN is identified by the VLAN ID in the tag. In an untagged frame,
the VLAN is the Port VLAN ID specified for the port that received this frame.
When disabled, all frames are forwarded in accordance with the 802.1Q VLAN
bridge specification. The factory default is disabled.

Acceptable Frame Type
Specifies the types of frames that may be received on this port. The options are
'VLAN only' and 'Admit All'. When set to 'VLAN only', untagged frames or
priority tagged frames received on this port are discarded. When set to 'Admit
All', untagged frames or priority tagged frames received on this port are
accepted and assigned the value of the Port VLAN ID for this port. With either
option, VLAN tagged frames are forwarded in accordance to the 802.1Q VLAN
specification.
