UNI

In this interface, you can set and query the UNI attributes of the Ethernet service.

Navigation Path

The E-Line, E-LAN or E-AGGR service requires information in this interface. The navigation paths for the three services are as follows:

In the NE Explorer, click the NE and choose Configuration > Ethernet Service Management > E-Line Service. Then click the UNI tab.
In the NE Explorer, click the NE and choose Configuration > Ethernet Service Management > E-LAN Service. Then click the UNI tab.
In the NE Explorer, click the NE and choose Configuration > Ethernet Service Management > E-AGGR Service. Then click the UNI tab.

Parameters

**Table 1** Descriptions of the parameters for an UNI Port
Field	Value	Description
Port	Slot-Board Name-Port (Port No)	Indicates the user-side port.
VLANs	1 to 4094	Queries and configures the VLAN ID. The VLAN ID can be null; or you can set one or more VLAN IDs.
Priority	0 to 7	Indicates the QoS level, which can be 0 to 7 in an ascending order. When the network is busy, data packets with a higher VLAN priority are processed first while those with a lower priority may be discarded.
SVLAN/SVLANs	1 to 4094	Specifies the S-VLAN ID of the UNI port. This parameter is valid only when Tag Type is set to S-Aware.
VLANs/CVLAN	1 to 4094	Specifies the VLAN ID of the UNI port. This parameter can be set to null, a number, or several numbers. When setting this parameter to several numbers, use the comma (,) to separate the discrete numbers, or use the endash (-) to represent a consecutive number. For example, the numbers 1, and 3-6 indicate 1, 3, 4, 5, and 6.
VLAN Filtering Table	1 to 4094	VLAN Filtering Table and VLANs/CVLAN cannot be set at the same time. But both parameters can be set to null, which means the port is exclusively occupied. If the service accessed by users involves 1000 or fewer VLANs, you can set VLANs/CVLAN directly. If the service involves more than 1000 VLANs, create a UNI interface that is exclusively occupied by a port and add the desired VLANs to the VLAN Filtering Table of the interface.
Enabled Packet Suppression	Enabled and Disabled	Sets whether to enable the broadcast packet suppression. Enabling the broadcast packet suppression efficiently prevents the broadcast storm and network congestion, and ensures the normal running of services. The E-LAN service supports this parameter.
Broadcast Packet Suppression Threshold (%)	0-100 Default: 30	Configures the threshold of the broadcast packet suppression. The E-LAN service supports this parameter. When the broadcast packet suppression is enabled, the broadcast packets are suppressed if the following requirement is met: Occupancy rate of the broadcast packet to the bandwidth of the current port > the total bandwidth of the port x the suppression threshold x 1%. A low occupancy rate indicates that the number of broadcast packets that pass through the port is small. If the occupancy rate is 100%, it indicates that the broadcast packets that pass through the port are not suppressed.
Unknow unicast Packet Suppression Threshold (%)	0-100	Configures the threshold of the unicast packet suppression. The E-LAN service supports this parameter.
Unknow multicast Packet Suppression Threshold (%)	0-100	Configures the threshold of the multicast packet suppression. The E-LAN service supports this parameter.
ID	For example, 1	Displays the ID of the UNI port. The E-AGGR service supports this parameter.
Location	Source, Sink	Displays the location of the UNI port. The E-AGGR service supports this parameter.
PB-UNI	Selected, Cleared Default: Selected	Indicates the network bridge type. If this check box is selected, the 802.1ad network bridge is used. If this check box is cleared, the VPLS network bridge is used. NOTE: This parameter is displayed only when S-Aware+IVL composite services are created between OptiX RTN 950As.
Enable Port	Enabled, Disabled	Display the enable status of the port.
Working Mode	For example: Auto-Negotiation	Working modes of the port. Be careful to configure the same working mode for the port and its interconnected port. Otherwise, service will fail.
Encapsulation Type	Null, 802.1Q, QinQ	Display the encapsulation type of the Ethernet port. 802.1Q indicates that a four-byte 802.1Q tag is inserted between the source MAC address section and the protocol type section. QinQ indicates that the 802.1Q is embedded with the 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.
1588 Clock Transmission	Enabled, Disabled	Specifies whether to transmit IEEE 1588 clock signals over Ethernet services. NOTE: This parameter can be set when S-Aware+IVL is not configured for the E-LAN services of an OSN 8800. This parameter can be set for the E-Line services of an OSN 8800.
Logical Port for 1588 Clock Transmission	Example: 2	Indicates the VLAN ID of the Ethernet service over which IEEE 1588 clock signals are transmitted. NOTE: This parameter can be set when 1588 Clock Transmission is Enabled. The value of this parameter must be within the value range of VLANs.
