inet-precedence (CoS Rewrite Rules)

Name of a rewrite-rules mapping configured at the [edit class-of-service rewrite-rules inet-precedence] hierarchy level.

The default mapping. By default, IP precedence rewrite rules alter the first three bits on the type of service (ToS) byte while leaving the last three bits unchanged.

For gr- interfaces (GRE tunnels) on MPCs, rewrite the inet-precedence CoS value to both the inner and outer header for Unicast/Multicast IPv4 traffic. The first three bits of the CoS value are rewritten and the final six bits are taken from the incoming CoS value.

For gr- interfaces on MPCs, rewrite the inet-precedence CoS value to the outer header for Unicast/Multicast IPv4 traffic. The first three bits of the CoS value are rewritten and the final six bits are taken from the incoming CoS value.

(Optional for ingress MPLS tunnel nodes) For interfaces on MX Series routers or hosted on Enhanced III FPCs in M120 or M320 routers only, rewrite the MPLS EXP bits in the MPLS header independently of the IPv4 DSCP value for IPv4 packets entering an MPLS tunnel.
