Configuring Server Load Balancing
In this section, I will explain how to configure real servers, server farms, and virtual servers in IOS SLB and CSMs.
IOS SLB
Configuration relating to SLB is done with the ip
slb command, or in SLB configuration mode. Real servers and virtual servers
must be on different VLANs when using SLB.
Real servers
When using SLB, real servers are not configured independently, but rather, within server farms.
Server farms
Server farms are created in SLB with the ip slb
serverfarm
farm-name command. Here, I've created a server farm named
GAD-FARM. The nat server command is a default and
will be inserted by IOS:
ip slb serverfarm GAD-FARM nat server
Tip
Don't bother trying to come up with names for your servers in lowercase or a combination of upper- and lowercase. No matter how you enter names when using SLB or CSMs, the parser will convert them to uppercase.
Once in ip slb configuration mode, add the real
servers to be included in the server farm with the real
ip-address command. Here, I've configured two real servers.
The first one is in service, and the second is out of service:
real 10.10.10.100 inservice ! real 10.10.10.101 no inservice
The final configuration for the server farm is as follows:
ip slb serverfarm GAD-FARM nat server real 10.10.10.100 inservice ! real 10.10.10.101 no inservice
Virtual servers
Virtual servers are configured in SLB with the ip slb
vserver
server-name command. You must configure the IP address for the virtual server, the port or ports ...
