Brocade Communications Systems 12.4.00 manual Specifying site locations, Syntax no gslb site name

1 Proxy for DNS server

ServerIronADX(config-gslb-site-sunnyvale)# si-name slb-2 209.157.22.210 200

NOTE

The administrative preference metric is disabled by default, which means it is not used by the GSLB policy. The GSLB policy uses the preference values only if you enable this metric. Refer to “Disabling or re-enabling individual GSLB policy metrics” on page 38.

Syntax: [no] gslb site <name>

The <name> parameter is a text string that uniquely identifies the site on the GSLB ServerIron ADX. You can enter a string up to 16 characters long. The string can contain blanks. To use blanks, enclose the string in quotation marks.

Syntax: [no] si-name [<name>] <ip-addr> [<preference>]

The si-name<name> parameter specifies a unique name for the ServerIron ADX at the site. You can enter a string up to 16 characters long. The string can contain blanks. To use blanks, enclose the string in quotation marks. You can enter up to four pairs of ServerIron ADX names and IP addresses on the same command line. The name is optional.

The <ip-addr>parameter specifies whether the remote site runs on the switch code or router code. If the remote site runs the switch code, enter the IP address configured on the site ADX. If it runs the router code, then enter the VE IP address on the site ADX.

In both cases, you must not enter a virtual IP address (VIP) configured on the ServerIron ADX or a source IP address added for source NAT.

The <preference> parameter sets the administrative preference for the site. When you enable the administrative preference as a GSLB metric, the administrative preference can be used by the GSLB policy when comparing this site with other sites. You can specify a preference from 0-255. The default preference is 128. The GSLB policy prefers high preference values over low preference values. If you specify 0, the site is administratively removed from selection by the GSLB policy but remains connected to the network. Refer to “Site ServerIron ADX’s administrative preference” on page 11 for information about uses for this parameter.

NOTE

If the GSLB ServerIron ADX itself is also a site for a host, the configuration steps are the same as for remote site ServerIron ADXs. Add a site definition and then specify the GSLB ServerIron ADX as the ServerIron ADX at the site. Specify the management IP address as the ServerIron ADX IP address.

NOTE

If traffic between the GSLB ServerIron ADX and a remote site ServerIron ADX must pass through a firewall, the firewall must be configured to allow traffic to and from the GSLB ServerIron ADX.

Specifying site locations

By default, the GSLB ServerIron ADX uses a site’s IP address to determine its geographic location. Alternatively, you can explicitly specify the location, by entering commands such as the following:

ServerIronADX(config)# gslb site sunnyvale

ServerIronADX(config-gslb-site-sunnyvale)# geo-location n-america

Syntax: [no] geo-location asia europe n-america s-america africa
