Configuring GSLB protocol parameters

To display public IP address information, enter the following command. The display shows that the
public IP address, 10.95.55.23, is used by both the local and peer GSLB ADX devices.
Syntax: show server virtual-name-or-ip
To display the IP address used for a VIP at a given GSLB site, enter the following command. The
example shows that the public IP address, 10.95.55.23, is used for the VIP at the site "local" on the
ADX device.
Syntax: show gslb site
Configuring GSLB protocol parameters
This section describes how to modify the following GSLB protocol parameters:
•
GSLB protocol port number: refer to
“Changing the protocol port number”
•
GSLB protocol update period: refer to
“Changing the GSLB protocol update period”
•
DNS response parameters: refer to
“Modifying GSLB parameters related to DNS responses”
•
GSLB policy parameters - refer to
“Changing the GSLB policy metrics”
Changing the protocol port number
By default, a GSLB Brocade Virtual ADX uses TCP port 182 to exchange GSLB information with
other Brocade Virtual ADXs, including the site ADX devices.
For example, if other devices in the network also use port 182, but for other applications, you need
to change the protocol on those devices or on the Brocade Virtual ADXs.
To change the GSLB protocol port, enter the following command.
Virtual ADX(config)#gslb communication 1882
Syntax: [no] gslb communication tcp-portnum
The tcp-portnum parameter specifies the TCP port number you want the Brocade Virtual ADX to use
for exchanging GSLB information with other Brocade Virtual ADXs.
If you change the GSLB protocol port number, you must write memory and reload the software to
place the change into effect. Also, you must change the port to the same number on all Brocade
Virtual ADXs in the GSLB configuration. If the port number in two GSLB Brocade Virtual ADXs is not
the same, those Brocade Virtual ADXs are not able to properly perform GSLB.
Changing the GSLB protocol update period
The GSLB protocol update period specifies how often the site ADX devices report their session
table statistics and CPU utilization to the GSLB Brocade Virtual ADX. The default update period is
30 seconds.
By default, each remote ADX device uses the GSLB protocol to send status information to the GSLB
Brocade Virtual ADX every 30 seconds. The status information consists of session utilization and
CPU load information, which you can display using the show gslb site command (refer to
