Layer 2 Attributes

In this interface, you can query and set the Layer 2 parameters of the Ethernet interface.

Navigation Path

For RTN NEs, in the NE Explorer, choose Configuration > Interface Management > Ethernet Interface from the navigation tree. Click Layer 2 Attributes tab.

In the NE Explorer, select a board and choose Configuration > Interface Management > Ethernet Interface from the navigation tree. Then, click the Layer 2 Attributes tab.

Parameters

**Table 1** Descriptions of the parameters for Ethernet interface Layer 2 Attributes
Field	Value	Description
Port	For example: Slot-Board Name-Port (Port No.)	Display the port name.
QinQ Type Domain	0x600 to 0xFFFF	Set the QinQ type domain. NOTE: This parameter is available only when you set Encapsulation Type in Basic Attributes to QinQ or 802.1Q.
TAG	Tag Aware, Access, Hybrid	The tag indicates which packets can be processed. Tag Aware: The port transparently transmits the data packet with a VLAN ID (tag). If a data packet does not have a VLAN ID (untag), the port discards this data packet. In this case, the Default VLAN ID and VLAN Priority are meaningless. Access: The port adds the default VLAN ID to the data packet without any VLAN ID (untag). If the data packet has a VLAN ID (tag), the port discards this data packet. Hybrid: The port adds the default VLAN ID to the data packet without any VLAN ID (untag). If the data packet has a VLAN ID (tag), the port transparently transmits the data packet. NOTE: This parameter is unavailable when you set Encapsulation Type in Basic Attributes to QinQ.
Default VLAN ID	For example: 94	Set the default VLAN ID of packets that passes through the port. When you set Tag to Access, packets that have the same VLAN ID as the default VLAN ID are discarded, and packets without a VLAN are added with the default VLAN ID and then pass the port. When you set Tag to Hybrid, tagged packets are allowed to pass, and packets without a tag are added with the default VLAN ID and then pass the port.
VLAN Priority	0 to 7	Set the QoS level. When the network is busy, data packets of higher VLAN priority are processed first and those of lower VLAN priority may be discarded. 0 indicates the lowest priority and 7 the highest.
SVLANs	1 to 4094	Indicates the S-VLAN ID. For an Ethernet service after the Tag of an SAI is set to Tag Aware, the SAI requires a C-VLAN or an S-VLAN of each user packet received to facilitate QoS traffic classification and priority scheduling. NOTE: This parameter is available when you set Encapsulation Type in Basic Attributes to 802.1Q.
