gNMI-1.23: Telemetry: Aggregate Interface Counters

Summary

Validate aggregate interfaces counters including both IPv4 and IPv6 counters. Also enable/disable the aggregate interface a few times and check if telemetry counters for interfaces are still available.

Testbed type

Test environment setup

The test uses a 4 port ATE setup where 1 port is used as a singleton interface and 3 other ports will be used as aggregate interface. The aggregate interface is a static LAG. Traffic will be sent using port1 and recieved by the port2,3,4 which are member ports of the aggregate interface.

Procedure

In the automated ondatra test, verify the presence of the telemetry paths of the following features:

  • Configure IPv4 and IPv6 addresses under aggregate subinterface:

    • /interfaces/interface/config/enabled
    • /interfaces/interface/config/enabled
    • /interfaces/interface/ipv4/config/enabled
    • /interfaces/interface/ipv6/config/enabled

    Validate that IPv4 and IPv6 addresses are enabled:

    • /interfaces/interface/ipv4/addresses/address/state/enabled
    • /interfaces/interface/ipv6/addresses/address/state/enabled

  • For the parent interface counters in-pkts and out-pkts:

    Check presence of packet counter paths and monitor counters every 30 sec: /interfaces/interface[name=aggregate port]/state/counters/in-pkts: /interfaces/interface[name=aggregate port]/state/counters/out-pkts:

  • Configure aggregate interfaces and assign 4 members to the aggregate interface:

    • For both static LAG Ensure that LAG is successfully negotiated, verifying port status for each of DUT ports 2-9 reflects expected LAG state via ATE and DUT telemetry. Ensure that below status with minimum links configuration on LAG Down when min-1 links are up Up when min links are up Up when >min links are up Poll the counters of the bundle interface and make sure all the counters are populated successfully

    • Now delete the bundle interface and reconfigure the bundle interface Ensure counters of the bundle interface are now populated successfully. /interfaces/interface/config/enabled

  • Interface counters: Check the presence of packet counter paths: /interfaces/interface[name=aggregate port name]/state/counters/in-pkts: /interfaces/interface[name=aggregate_port_name]/state/counters/out-pkts: /interfaces/interface[name=aggregate_port_name]/state/counters/in-octets: /interfaces/interface[name=aggregate_port_name]/state/counters/state/counters/out-octets: /interfaces/interface[name=aggregate_port_name]/state/counters/state/counters/in-unicast-pkts: /interfaces/interface[name=aggregate_port_name]/state/counters/state/counters/in-broadcast-pkts: /interfaces/interface[name=aggregate_port_name]/state/counters/state/counters/in-multicast-pkts: /interfaces/interface[name=aggregate_port_name]/state/counters/state/counters/in-errors: /interfaces/interface[name=aggregate_port_name]/state/counters/state/counters/in-discards: /interfaces/interface[name=aggregate_port_name]/state/counters/state/counters/out-unicast-pkts: /interfaces/interface[name=aggregate_port_name]/state/counters/state/counters/out-broadcast-pkts: /interfaces/interface[name=aggregate_port_name]/state/counters/state/counters/out-multicast-pkts: /interfaces/interface[name=aggregate_port_name]/state/counters/state/counters/out-errors: /interfaces/interface[name=aggregate_port_name]/state/counters/state/counters/out-discards: /interfaces/interface[name=aggregate_port_name]/state/counters/state/counters/last-clear:

  • Interface CPU and management Check the presence of CPU and management paths:

    • TODO: /interfaces/interface/state/cpu
    • TODO: /interfaces/interface/state/management
