•

Frame Type—Specifies the frame type accepted on the port:

-

Admit Untagged Only—Only untagged frames are accepted on the 
port. Tagged frames are discarded.

-

Admit Tagged Only—Only tagged frames are accepted on the port. 
Untagged frames are discarded.

-

Admit All—Both tagged and untagged frames are accepted on the port. 

An access port can admit untagged frames only. A trunk port can be 
assigned to only one untagged VLAN, called the native VLAN and, can be 
assigned to any number of tagged VLANs (or none). If a trunk port is member 
of both untagged and tagged VLANs, it admits all frame types. If the trunk 
port is member of tagged VLANs only, it admits tagged frames only. 

•

Ingress Filtering—Select to enable ingress filtering on the port. When 
ingress filtering is enabled, the switch accepts frames only from the VLANs 
of which it is a member. It discards frames received from other VLANs. All 
ports in access or trunk mode will always have their Ingress Filtering 
enabled. Disabling and enabling Ingress Filtering is only available on ports 
set to General Mode. 

•

VLAN Priority—The default 802.1p priority value for the port. The value will 
be applied to the incoming packets based on the QoS trust mode configured 
at the port and the types of the packets. See 

 for information 

and instructions on configuring the port trust mode.

Click Apply and then click Close. Your changes are saved to the Running 
Configuration.

When the interface VLAN mode of a port is changed, the switch automatically 
handles the affected VLAN membership configuration, as follows:

The VLAN configuration remains unchanged. The Access port VLAN becomes the 
native VLAN for the Trunk port. The port must follow the restrictions for Trunk 
ports.
