Policy forwarding table sensor on JTI

You can use Junos telemetry interface (JTI) and remote procedure calls (gRPC) services to stream policy forwarding table statistics on devices to outside collectors.

The following resource paths are supported:

• /network-instances/network-instance/afts/next-hop-groups/next-hop-group/conditional/condition/
• /network-instances/network-instance/afts/next-hop-groups/next-hop-group/conditional/condition/ id
• /network-instances/network-instance/afts/next-hop-groups/next-hop-group/conditional/condition/state/id
• /network-instances/network-instance/afts/next-hop-groups/next-hop-group/conditional/condition/ state/dscp[]
• /network-instances/network-instance/afts/next-hop-groups/next-hop-group/conditional/condition/state/next-hop-group
• /network-instances/network-instance/afts/next-hop-groups/next-hop-group/conditional/condition/input-interfaces/input-interface
• /network-instances/network-instance/afts/next-hop-groups/next-hop-group/conditional/condition/ input-interfaces/input-interface/id
• /network-instances/network-instance/afts/next-hop-groups/next-hop-group/conditional/condition/ input-interfaces/input-interface/state/id
• /network-instances/network-instance/afts/next-hop-groups/next-hop-group/conditional/condition/ input-interfaces/input-interface/state/interface
• /network-instances/network-instance/afts/next-hop-groups/next-hop-group/conditional/condition/ input-interfaces/input-interface/state/subinterface

The Junos OS class-of-service (CoS) classifiers do the code-point (CP) to forwarding-class (FC) and loss-priority (LP) mapping. The classifier used depends on the family configured on the logical interface.

Devices running Junos OS support the following classifier types:

• Differentiated Services code point classifier (DSCP)
• DSCP IPv6
• MPLS EXP classifier inet-precedence
• IPv4 precedence classifier
