Brocade Communications Systems 12.4.00 Disabling or re-enabling individual Gslb policy metrics

1 Configuring GSLB protocol parameters

•active bindings: The ServerIron ADX’s preference for the IP address with the highest number of active bindings.

•capacity: The remote ServerIron ADX’s session capacity threshold.

•connection-load:The site ServerIron ADX’s average number of new connections per second

•flashback: The site ServerIron ADX’s FlashBack speed (how quickly the GSLB receives the health check results)

•geographic: The geographic location of the server

•health-check: The Layer 4 and application health checks

•num-session: The remote ServerIron ADX’s available session capacity

•preference: The administratively configured preference for the site ServerIron ADX

•round-trip-time: The round-trip time between the remote ServerIron ADX and the DNS client

•weighted ip: The administratively configured traffic distribution method for the ServerIron ADX

•weighted site: The administratively configured traffic distribution method for the ServerIron

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.

ServerIronADX(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” on page 177.

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:

ServerIronADX(config)# gslb policy

ServerIronADX(config-gslb-policy)# no health-check

ServerIronADX(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 ServerIron ADX does not perform any health checks on the remote sites. If you disable the RTT metric, the GSLB ServerIron ADX instructs the site ServerIron ADXs to stop sending RTT information.

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.
