[CAUSE] The notification tmnxSrrpPrivRetailMismatch is generated with a value of 'true' for tmnxMcNotifyServiceId when the list of private retail services received through SRRP-MCS synchronization does not match the list that is locally configured on this system, or with a value of 'false' when a matching list of private retail services is received subsequently. [EFFECT] Downstream traffic received on the standby system for a subscriber associated with a misconfigured retail service can not be forwarded. [RECOVERY] Restore consistency in the configuration of the private retail services on both systems.
