Table 161: VLAN Switchport Summary Fields
Field
Description
Interface
The interface associated with the rest of the data in the row. When editing
information for one or more interfaces, this field identifies the interfaces that are
being configured.
Switchport Mode
The switchport mode of the interface, which is one of the following:
•
Access — Access mode is suitable for ports connected to end stations or
end users. Access ports participate only in one VLAN. They accept both
tagged and untagged packets, but always transmit untagged packets.
•
Trunk — Trunk mode is intended for ports that are connected to other
switches. Trunk ports can participate in multiple VLANs and accept both
tagged and untagged packets.
•
General — General mode enables a custom configuration of a port. The
user configures the General port VLAN attributes such as membership, PVID,
tagging, ingress filter, etc., using the settings on the Port Configuration page.
By default, all ports are initially configured in General mode.
Access VLAN ID
The access VLAN for the port, which is valid only when the port switchport
mode is Access.
Native VLAN ID
The native VLAN for the port, which is valid only when the port switchport mode
is Trunk.
Native VLAN Tagging
When enabled, if the trunk port receives untagged frames, it forwards them on
the native VLAN with no VLAN tag. When disabled, if the port receives untagged
frames, it includes the native VLAN ID in the VLAN tag when forwarding.
Trunk Allowed VLANs
The set of VLANs of which the port can be a member, when configured in Trunk
mode. By default, this list contains all possible VLANs even if they have not yet
been created.
Use the buttons to perform the following tasks:
•
