Hierarchy Level


Class-of-service (CoS) value given to all packets in the bypass LSP. You can specify a single CoS value for all the bypass LSPs traversing an interface. You can also configure CoS values for specific bypass LSPs traversing an interface.

The CoS value might affect the scheduling or queuing algorithm of traffic traveling along an LSP.


cos-value—CoS value. A higher value typically corresponds to a higher level of service.

  • Range: 0 through 7

  • Default: If you do not specify a CoS value, the IP precedence bits from the packet’s IP header are used as the packet’s CoS value.
