Severity: 3-Major

Symptoms

TMM crashes when the statistics of the crypto client is reset when the External Crypto Offload feature is not licensed and the client configured with an unreachable crypto server. The command to reset the statistics of a crypto client is below: tmsh reset-stats sys crypto client [<client name>]

Impact

Traffic is temporarily disrupted while TMM restarts.

Conditions

With a crypto client configured to target an invalid or unreachable crypto server and the External Crypto Offload (ECO) feature is not licensed, reset the statics of the crypto client.

Workaround

Ensure the External Crypto Offload feature is licensed and/or target a valid crypto server when creating the crypto client.

Fix Information

Reset statistics for a crypto client only when a HUD proxy has been instantiated.
