4. Under Layer 3 Ping Check, provide the following information:
• Real Server: Select the Enable check box to enable Layer 3 ping check on the real server.
The Brocade Virtual ADX uses the IP ping to determine whether the slowed response time
indicates loss of the real server If the time between the last packet sent to the real server
and the last packet received from the real server increases.
• Remote Server: Select the Enable check box to enable Layer 3 ping check on the remote
server.
The Brocade Virtual ADX uses the IP ping to determine whether the slowed response time
indicates loss of the remote server if the time between the last packet sent to the remote
server and the last packet received from the remote server increases.
• Ping Interval: Enter the ping interval for Layer 3 ping check, in seconds. The range is from
1 through 10 seconds. The default is 5 seconds.
• Ping Retries: Specifies the number of times that the Brocade Virtual ADX will ping a real
server before changing the server state to FAILED. Enter the number of ping retries for
Layer 3 ping check. The range is from 2 through 10. The default is 4.
5. Under Layer 4 TCP/UDP Check, provide the following information:
• Layer 4 Health Check: Select the Enable check box for Layer 4 health check.
When you bind a real server to a virtual server, the Brocade Virtual ADX performs either a
Layer 4 TCP health check, a Layer 4 UDP health check, or a Layer 7 health check to bring
up the application port that binds the real and virtual servers. The Layer 4 health check
can be a TCP check or a UDP check.
• Fast Port Bring-up: Select the Enable check box to increase the speed of the bringup
process by sending more (up to a maximum of 50) health-checks at one time.
6. Under Other, provide the following information:
DSR Use Master State: Select the Enable check box to use the first DSR binding state for
all additional DSR bindings. The health check occurs on the first VIP only. By default, this
feature is disabled.
7. Click Apply to save your entries.
Click Reset to revert the configuration to the previous configured values.
For more information on configuring health checks, refer to the Brocade Virtual ADX Server Load
Balancing Guide.
Creating a port profile
A port profile is a set of attributes that globally defines an application port. Once defined, the port
has the same attributes on all the real and virtual servers that use the port. Port profiles are useful
if you want to globally change the attributes of a port known to the Brocade Virtual ADX or you want
to globally define a port that is not known to the Brocade Virtual ADX.
Define a port profile to globally configure the port parameters and configure the keepalive health
check.
