Table 31 VLAN tab items for a single port
Item Description
Type Indicates the type of VLAN port (Trunk or Access port). If the
port is a trunk port, the port is probably a member of more
than one VLAN. If the port is an access port, the port can only
be a member of one VLAN if there is no membership conflict.
VlanIds The VLANIDs of which this port is a member.
DiscardTagged Frames This field only applies to access ports. It acts as a flag used to
determine how to process tagged frames received on this
port. When the flag is set, the frames are discarded by the
forwarding process. When the flag is reset, the frames are
processed normally.
DiscardUntaggedFrames This field only applies to trunk ports. It acts as a flag used to
determine how to process untagged frames received on this
port. When the flag is set, the frames are discarded by the
forwarding process. When the flag is reset, the frames are
assigned to the VLAN specified by rcVlanPortDefaultVlanId.
DefaultVlanId The VLAN ID assigned to untagged frames received on a
trunk port.
Port Allows you to change the switch port being viewed.
