The reason is the reason the Brocade Virtual ADX

of the following:
•
healthck – The port failed a health check. This
applies to standard health checks and Boolean
health checks.
•
reassign – The reassign threshold was reached.
•
server-down – The server failed the Layer 3 health
check when you bound the real server to the VIP.
•
MAC-delete – The server’s MAC address was
deleted from the Brocade Virtual ADX MAC table.
•
graceful-shutdown – The server was gracefully shut
down.
•

application (by something other than the Brocade
Virtual ADX.)
•
unknown – The port was brought down by a reason
other than one of those listed above.
