Symptoms

When Virtual Edition (VE) is licensed with limited throughput, tmm checks and enforces rate limits. However, due to the nature of clustering in data plane, individual tmm processes performs the check independently (that is, divided by the number of tmms on the system). Thus, the check result is not accurate from global rate perspective. In this case, the system log messages that indicates data rate exceeds licensed rate.

Impact

Message indicating data rate exceeds licensed rate.

Conditions

Multiple tmm in VE and licensed with limited date rate, when only some of the tmms are processing traffic.

Workaround

None.

Fix Information

Incorrect and benign log message of bandwidth utilization exceeded when licensed with rate limit in Virtual Edition no longer occurs.
