Customer planned to enable LACP traceoptions for troubleshooting intermittent LACP issues on an AE interface.

Customer wanted to understand the operational impact of the following configuration: set protocols lacp traceoptions flag all

Concerns included:

• Potential impact to live production traffic.
• Possible interface flaps.
• Potential LACP process restart.
• Service interruption during troubleshooting activities

Enabling LACP traceoptions does not restart physical interfaces, AE interfaces, or the LACP protocol process.

When the following configuration is committed:

set protocols lacp traceoptions flag all

The device begins collecting LACP debug information and writing it to trace logs. This action is considered non-disruptive and is commonly used during troubleshooting activities.

No traffic disruption is expected solely from enabling LACP traceoptions.

Expected behavior:

• Existing LACP sessions remain established.
• Member links remain active.
• AE interfaces continue forwarding traffic.
• No protocol restart occurs.
• No interface reset occurs.

Considerations

Traceoptions increase logging activity and may consume additional system resources depending on the amount of generated debug data.

For extended troubleshooting sessions:

• Monitor /var/log utilization.
• Remove debug tracing after data collection is completed.
• Consider limiting trace flags if excessive logging is observed.
