Performance issues
Symptom General slow-down in FCR performance and scalability.
Probable cause and recommended action
As LSAN zone databases get bigger, it takes more switch resources to process them. Use the
enforce tag feature to prevent a backbone switch from accepting unwanted LSAN zone databases
into its local database.
