TAG Attributes

In this user interface, you can query and set the TAG attribute for a PORT port or a VCTRUNK port.

Navigation Path

In the NE Explorer, select a board and choose Configuration > Ethernet Interface Management > Ethernet Interface from the Function Tree. Click the TAG Attributes tab. For PORT, select External Port; for VCTRUNK, select Internal Port.

Note

All data packets that enter an Ethernet board have tags.
Though a port set to Hybrid processes all types of data packets, be careful when setting a port to Hybrid. For example, when the opposite equipment (such as a computer) receives untagged data packets only, if the egress data packets carry a VLAN ID that is different from the VLAN ID of the port, the data packets are directly transparently transmitted. However, the opposite equipment cannot identify the data packets and discard them. As a result, services are interrupted.

Parameters

Field	Value	Description
Port	PORTn or VCTRUNKn	PORT port or VCTRUNK port. "n" is the port number.
Name	For example: VCTRUNK-1	Indicates the name of a port. This name can be changed manually.
TAG	Tag Aware, Access, Hybrid Default: Tag Aware	The tag is used for setting which type of data packets can be processed. Set this parameter to Tag Aware to enable the port to transparently transmit packets that have the VLAN ID (tag). If packets do not have the VLAN ID (untag), the packets are discarded. Default VLAN ID and VLAN priority cannot be edited. Set this parameter to Access to enable the port to add the default VLAN ID to packets that do not have the VLAN ID (untag). If the packets have the VLAN ID (tag), the packets are discarded. Set this parameter to Hybrid to enable the port to add the default VLAN ID to the packets that do not have the VLAN ID (untag). If the packets have the VLAN ID (tag), the packets are transparently transmitted. The tag attribute is effective only when the network attribute of the port is PE or UNI.
Default VLAN ID	1-4095 Default: 1	The Default VLAN ID (Ethernet Port Attribute) parameter specifies the default VLAN ID of a port.
VLAN Priority	0-7 Default: 0	The VLAN Priority (Ethernet Port Attribute) parameter specifies the priority of the default VLAN ID of a port. It indicates the priority of the service quality.
Entry Detection	Enabled, Disabled Default: Enabled	The Entry Detection (Ethernet Port Attribute) parameter specifies whether to identify the tag labels in the data packets.
