GSLB optimization
1
Increased VIP support per site and reduced CPU usage on GSLB
controller
Through use of the VIP List Optimize feature the maximum number of GSLB-enabled VIPs
supported per site is 1024 VIPs per site.
Use the following commands on controller and site to avail this functionality.
1. On controller, enable VIP list process optimization by issuing the following command at global
config level.
Virtual ADX(config)#gslb process-vip-list-optimize
Virtual ADX(config)#write memory
Virtual ADX(config)#reload
NOTE
A system reload is required after enabling the gslb process-vip-list-optimize command.
2. Under a site definition on the controller, add the si si-ip-address optimized-dist-hcheck
command.
Virtual ADX(config)#gslb site sunnyvale
Virtual ADX(config-gslb-site-sunnyvale)#si-name si-1 10.1.1.1
Virtual ADX(config-gslb-site-sunnyvale)#si 10.1.1.1 optimized-dist-hcheck
Syntax: [no] si ip-address optimized-dist-hcheck
The si ip-address optimized-dist-hcheck helps the controller identify the site that has the VIP
list process optimization enabled.
NOTE
on the Controller (configured gslb process-vip-list-optimize saved
the configuration and reloaded the device), the message: "Please enable hashing to
optimize vip list processing and reload!"
will be displayed on the Controller SI
when you configure this command on the Site SI and reload.
3. Issue the gslb send-vip-list-optimize command on the Site Virtual ADX.
Site-Virtual ADX(config)#gslb send-vip-list-optimize
Site-Virtual ADX(config)#write memory
Site-Virtual ADX(config)#reload
Syntax: [no] gslb send-vip-list-optimize
NOTE
A system reload is required after enabling this feature.
4. If site Virtual ADX is hosting more than 217 GSLB enabled VIPs, then you need to disable the
site Virtual ADX from sending active binding information. Issue the following command.
Site-Virtual ADX(config)#gslb dont-send-active-bindings
Syntax: [no] gslb dont-send-active-bindings
