Impact

Since these errors are reported for the interface that is used to retrieve stats from the Broadcom switch chip, they are not expected to impact the packet path/traffic passing.

Conditions

This error is logged if an internal parity error is reported by the Broadcom switch chip when stats are read from the chip by BIG-IP.

Workaround

To work around this issue, you can restart the bcm56xxd process on the affected appliance or blade. To do so, perform the following procedure: Impact of workaround: The BIG-IP system stops processing traffic. You should perform this operation only during a maintenance window or when the system is in a standby state. 1. Log in to the BIG-IP command line of the affected appliance or blade as the root user. 2. Run the following command: bigstart restart bcm56xxd.
