Message format string

Bridge $tmnxCustomerBridgeId$ with root bridge $tmnxCustomerRootBridgeId$ has higher priority, for service $svcId$ (customer $custId$) on SAP $sapEncapValue$

Cause

A customer's device has been configured with a bridge priority equal to zero.

Effect

The SAP that the customer's device is connected through will be blocked.
