Syntax: show gslb active-rtt-info
In the sample output above, the ServerIron ADX is both a GSLB ServerIron ADX as well as a Site
ServerIron ADX. If the ServerIron ADX is a GSLB ServerIron ADX, information only for the GSLB
controller will be displayed. Likewise, if the ServerIron ADX is only a Site ServerIron ADX, only
information for the Agent will be displayed.
TABLE 9 Show GSLB active RTT information
This field... Displays...
Controller This area shows information about the GSLB ServerIron ADX.
Active RTT gathering State of active RTT gathering mechanism on the GSLB ServerIron
ADX: Enabled or Disabled.
Discard Passive RTT recvd. from agent Shows the GSLB ServerIron ADX is configured to discard any passive
RTTs received from Site ServerIron ADXs.
Interval to send active rtt query buffer to
agent The interval at which the GSLB ServerIron ADX sends query buffer
containing LDNS prefixes to Site ServerIron ADXs.
DNS probe Indicates if controller has been configured to accept RTT
information gathered using DNS probes.
Possible values: ENABLE or DISABLE
Fallback Indicates if fallback mechanism has been enabled on the controller.
If enabled, controller will use DNS RTT information. If this is not
available, it will use ICMP RTT information. If disabled, controller will
only use ICMP RTT information.
Agent This area shows information about the Site ServerIron ADX.
Num active RTT peers Number of passive RTT GSLB ServerIron ADXs for which this
ServerIron ADX is a Site ServerIron ADX.
