MPLS-TP Shared Protection Ring Management

Shared protection rings are rings in opposite directions that protect each other. There are working and protection channels in each direction. By providing redundant bandwidth or network devices, the shared protection rings restore distributed services automatically and quickly when a network failure occurs or performance deteriorates.

Navigation Path

In the NE Explorer, select an NE and choose Configuration > Packet Configuration > MPLS Management > MPLS-TP Shared Protection Ring Management from the Function Tree.

Buttons

Button		Description
Delete		Deletes an MPLS-TP shared protection ring. Updating the ring topology for other nodes is required after a ring is deleted. NOTICE: Do not delete rings with services. Do not delete rings with virtual intersecting nodes.

Parameters

**Table 1** Descriptions of the parameters for MPLS-TP shared protection ring management
Field	Value	Description
Ring ID	1 to 65535	Indicates the network-wide unique ID of a ring.
Ring Network Name	Example: SPRing	Indicates the name of a ring.
Ring Node ID	For a real ring node: 1-127 For a virtual ring node: 128-255	Indicates the unique ID of a node on a ring.
East Interface	Example: 5-D2EG2-1(PORT-1)	Indicates the east port. Each node on a ring has two ports that can receive and transmit packets: east port and west port. The first port in the clockwise direction is the east port.
Next Hop (East)	Example: 41.52.2.53	Indicates the IP address of the next hop in the east.
West Interface	Example: 6-EF8T-2(PORT-2)	Indicates the west port. Each node on a ring has two ports that can receive and transmit packets: east port and west port. The first port in the anticlockwise direction is the west port.
Next Hop (West)	Example: 41.55.8.29	Indicates the IP address of the next hop in the west.
MTU (byte)	Example: 46	Indicates the maximum transmission unit (MTU) of a shared protection ring. A packet whose size is greater than the MTU will be discarded.
VLAN ID of East Channel	1 to 4094	Indicates the VLAN ID of all channels in the east direction on a ring.
VLAN ID of West Channel	1 to 4094	Indicates the VLAN ID of all channels in the west on a ring.
CIR (kbit/s)	Example: 1600	Indicates the committed information rate (CIR). NOTE: The CIR cannot be higher than the PIR. The sum of CIRs of all VLAN sub-interfaces on a port cannot be higher than the physical bandwidth of the port.
CBS (bytes)	Example: 2400	Indicates the committed burst size (CBS).
PIR (kbit/s)	Example: 3600	Indicates the peak information rate (PIR). NOTE: The sum of PIRs of all VLAN sub-interfaces on a port cannot be higher than the physical bandwidth of the port.
PBS (bytes)	Example: 4800	Indicates the peak burst size (PBS).
Occupied Bandwidth of East Channel (kbit/s)	Example: 123	Indicates the occupied bandwidth on the east channel.
Occupied Bandwidth of West Channel (kbit/s)	Example: 256	Indicates the occupied bandwidth on the west channel.
Remaining Bandwidth of East Channel (kbit/s)	Example: 654	Indicates the remaining bandwidth on the east channel.
Remaining Bandwidth of West Channel (kbit/s)	Example: 248	Indicates the remaining bandwidth on the west channel.
East Working Channel EXP	None, 0 to 7	Indicates the priority of packets on the east working channel. A larger value indicates a higher priority. For example, the value 7 indicates the highest priority. Queue scheduling and packet discarding depend on the value of this parameter. NOTE: The priority of the working channel cannot be lower than the priority of the protection channel.
East Protection Channel EXP	None, 0 to 7	Indicates the priority of packets on the east protection channel. NOTE: The priority of the working channel cannot be lower than the priority of the protection channel.
West Working Channel EXP	None, 0 to 7	Indicates the priority of packets on the west working channel. NOTE: The priority of the working channel cannot be lower than the priority of the protection channel.
West Protection Channel EXP	None, 0 to 7	Indicates the priority of packets on the west protection channel. NOTE: The priority of the working channel cannot be lower than the priority of the protection channel.
Deployment Status	Deployed, Undeployed	Deployed: Indicates that the configuration data of the shared protection ring has been applied to NEs. Undeployed: Indicates that the configuration data of the shared protection ring has not been applied to NEs.
Ring Squelch	Enabled, Disabled	If you set Ring Squelch to Enabled, the NE functions as a fault detection point on the MPLS-TP ring to check the connectivity of protected services to the destination node. If faults are found and the destination node is unreachable, the services are directly discarded rather than being switched to the protection route on the fault detection point, which helps prevent a loop storm.
