Deleting an MPLS Tunnel on a Per-NE Basis

As a transmission technology, the multi-protocol label switching (MPLS) can realize transparent transmission of data packets among users. The MPLS tunnel is the tunnel defined in the MPLS protocol. Independent from the service, the MPLS tunnel realizes the end-to-end transmission and carries the PWs related to the service.

Navigation Path

In the NE Explorer, click the NE and choose Configuration > Packet Configuration > MPLS Management > Unicast Tunnel Management from the Function Tree. Then, click the Static Tunnel tab.

Remote Tunnel ID	Example: 398	Each of the two intersecting nodes has a tunnel. One tunnel works as the active tunnel while the other works as the standby tunnel. Since the two tunnel IDs are different, the remote tunnel ID will be saved for a tunnel at each node for unified management. NOTE: This parameter can be set when Node Type is Transit, and Outbound Bearer Type and Inbound Bearer Type are MPLS-TP Shared Protection Ring.
Role	Active, Standby	Only two intersecting nodes are configured on the two-fiber bidirectional intersecting rings. The two tunnels that pass through the two intersecting nodes separately are configured as active and standby tunnels, so that if one intersecting node fails, services can pass through the other intersecting node. Services will choose the standby tunnel when the active tunnel is not available. NOTE: This parameter can be set when Node Type is Transit, and Outbound Bearer Type and Inbound Bearer Type are MPLS-TP Shared Protection Ring. The active and standby roles are configured for management convenience. The actual service direction depends on the switching status of the shared protection ring other than the role configurations.

Secondary Reverse Label	16 to 1048575	Specifies the reverse label of the standby tunnel.
Switching Triggered by Packet Loss Rate	Enabled, Disabled	Specifies whether to trigger switching when the packet loss rate exceeds thresholds. After you set Switching Triggered by Packet Loss Rate to Enabled, SD Threshold and SF Threshold are available. If the packet loss rate on a tunnel exceeds the preset SD or SF threshold, tunnel protection switching is triggered.
SD Threshold	1.0E-2, 1.0E-3, 1.0E-4, 1.0E-5, 1.0E-6	Indicates the threshold of SD caused by packet loss.
SF Threshold	1.0E-2, 1.0E-3, 1.0E-4, 1.0E-5, 1.0E-6	Indicates the threshold of SF caused by packet loss.
Tunnel Bandwidth Limatation	Enabled, Disabled	The parameter can be set when the Deployment Status is deployed. Set as Enabled, the apply of CIR (kbit/s) and PIR (kbit/s) can be success.
