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.
Symptom
Host application times out.
Probable cause and recommended action
The FCR tends to take a long time (more than 5 seconds) to present and
set up paths for the proxy devices. Certain hosts are able to do discovery
much faster and, as a result, they end up timing out. Use the speed tag
feature to always present the target proxy to the host. This helps sensitive
hosts to do a quick discovery without timing out or causing an application
failure.
