Cisco Small Business SG200 Series 8-port Smart Switch 106

• 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 QoS Properties for information
and instructions on configuring the port trust mode.

Changing the Interface VLAN Mode
When the interface VLAN mode of a port is changed, the switch automatically
handles the affected VLAN membership configuration, as follows:
Changing from Access Port to Trunk Port
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.
