Virtual ADX
There are no parameters for the Least Response Selection or Round Robin Selection metrics.
These metrics are tie-breakers. Only one of them is enabled at a time and the one that is enabled is
always the last metric in the policy.
To reset the order of the GSLB policy metrics to the default (and also re-enable all disabled
metrics), enter the following command.
Virtual ADX(config-gslb-policy)#metric-order default
Syntax: metric-order default
The no metric-order set command also resets the order and re-enables all disabled metrics. This
command is equivalent to the metric-order default command.
To display the GSLB policy after you change it, enter the show gslb policy command. Refer to
“Displaying the user-configured GSLB policy”
Disabling or re-enabling individual GSLB policy metrics
You can explicitly disable individual GSLB policy metrics. For example, to disable the health check
and geographic metrics, enter commands such as the following.
Virtual ADX(config)#gslb policy
Virtual ADX(config-gslb-policy)#no health-check
Virtual ADX(config-gslb-policy)#no geographic
Syntax: [no] health-check | num-session | preference | round-robin | round-trip-time | geographic
| connection-load limit average-load | capacity | flashback
The average-load parameter can be from 1 to as high a value as you need. There is no default. You
must specify a connection limit to enable the connection limit metric.
NOTE
If you explicitly disable both the health check and flashback metrics, the GSLB Brocade Virtual ADX
does not perform any health checks on the remote sites.
To enable a metric, enter the command without “no” in front of it. For example, to re-enable both
the metrics disabled in the preceding example, enter the following commands.
Virtual ADX(config)#gslb policy
Virtual ADX(config-gslb-policy)#health-check
Virtual ADX(config-gslb-policy)#geographic
