Parameters

Parameter

Description

Value

smartqos_policy_id=? ID of the SmartQoS policy whose performance statistics you need to collect.

To obtain the value, run "show smartqos_policy general".

smartqos_policy_id_list=? ID list of SmartQoS policies whose performance statistics you need to collect.
  • To obtain the value, run "show smartqos_policy general".
  • Separate the IDs with commas (,).
  • A maximum of 50 IDs can be queried.
