Symptoms

Device DoS thresholds are divided between FPGAs. When there are odd number of TMMs, then values are swapped. Because of this there will be a small increase in allow or drop packets compared with the configured thresholds.

Impact

There will be a small increase in allow or drop packets compared with configured thresholds.

Conditions

- This issue will be seen only in Appliance devices with two ATSEs. - When there are odd number of TMMs running inside the tenant.

Workaround

Create tenant with vcpu cores as 4,8,12,16 e.t.c which results in even number of tmms.

Fix Information

The FPGA can be configured with correct device DoS threshold configurations.
