Layer 4 health checks

To display configuration information and statistics for the real server configured on the Brocade
Virtual ADX, enter the following command:
The fields in bold provides the following information:
• The Bring port down for RTT field displays the number of times the port has been marked down
because it has exceeded the configured response threshold. This can be Layer 4, Layer 7, or
combined Layer 4 and 7.
• The Current TCP RTT field displays in microseconds the current TCP round trip time. If this
value exceeds the configured l4 response threshold, the port is brought down.
