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 ServerIron ADX uses TCP port 182 to exchange GSLB information with other
ServerIron ADXs, including the site ServerIron ADXs.
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 ServerIron ADXs.
To change the GSLB protocol port, enter the following command.
ServerIronADX(config)#gslb communication 1882
Syntax: [no] gslb communication <tcp-portnum>
