Configuring the maximum ports per VIP address in a VIP address list message
The site ADX device sends a VIP address list message that contains a list of VIP addresses, VIP
ports, and associated health and other information to the GSLB controller. By default, each site
ADX device can send up to 10 ports for each VIP address. You can configure the site ADX device to
send health status of up to 30 ports per VIP address in a VIP address list message.
To configure the maximum number of ports per VIP address in a VIP address list message, enter
the gslb max-vip-list-ports command.
Virtual ADX(config)# gslb max-vip-list-ports 20
Syntax: [no] gslb max-vip-list-ports max-ports
NOTE
The site ADX device can send up to 30 ports per VIP address only when both the GSLB controller and
the site ADX run release 12.4.00g or later. If either the GSLB controller or the site ADX is running a
release prior to release 12.4.00g, the site ADX can send only a maximum 10 ports per VIP address.
The max-ports variable is the maximum number of ports per VIP address in a VIP address list
message from each site ADX device. The number of ports ranges from 5 through 30. The default
number of ports is 10.
The no form of the command resets the number of ports to the default setting of 10.
For information on displaying VIP address list messages, refer to “Debugging the distributed health
check” on page 80.
Configuring the health status reporting interval
If the GSLB Brocade Virtual ADX supports the distributed health check feature, then you can
globally configure the interval at which the distributed health check site ADX devices report the
health check information to the GSLB Brocade Virtual ADX for the GSLB distributed health check
feature. Note that if health status interval is configured globally, it applies to all peer site ADX
devices that support the distributed health check feature.
To globally configure the health status reporting interval, enter commands such as the following on
the GSLB Brocade Virtual ADX.
GSLB-Virtual ADX(config)#gslb policy
GSLB-Virtual ADX(config-gslb-policy)#health-status-interval 3
Syntax: [no] health-status-interval secs
The secs parameter specifies the interval. Range is 2 – 120 seconds.
Configuring the agent health report interval
If both the GSLB Brocade Virtual ADX and the site ADX device support the distributed health check
feature, you can configure the interval at which the site ADX device reports the health check
information to the GSLB Brocade Virtual ADX for the GSLB distributed health check feature. To do
this, enter a command such as the following.
SITE-Virtual ADX(config)#agent-health-report-interval 7
Syntax: [no] agent-health-report-interval secs
The secs specifies the interval. Range is 2 – 120 seconds.
