Open Config model defines the multiple leaf's which measure the speed of the interface, this article discuss about the leaf that should be used for measuring the ae bundle speed.

Open Config leaf for monitoring the speed of ae bundle 

The open config leaf lag-speed should be used to measure the ae bundle speed. 

Below is the value from the lag-speed leaf on interface ae187 having 4 members with 400G each. Hence the lag-speed value is 1600G(4x400G)

  str_value: /interfaces/interface[name='ae187']/

  key: aggregation/state/lag-speed

  uint_value: 1600000

  key: __prefix__


When 2 ae members were removed, the lag-speed changes from 1600G(4x400G) to 800G(2x400G).

  str_value: /interfaces/interface[name='ae187']/

  key: aggregation/state/lag-speed

  uint_value: 800000

  key: __prefix__


When 1 ae member was added, the lag-speed change from 800G(2x400G) to 1200G(3x400G)

  str_value: /interfaces/interface[name='ae187']/

  key: aggregation/state/lag-speed

  uint_value: 1200000

  key: __prefix__

When the last ae member was added, the lag-speed change from 1200G(3x400G) to 1600G(4x400G)

  str_value: /interfaces/interface[name='ae187']/

  key: aggregation/state/lag-speed

  uint_value: 1600000

  key: __prefix__
