Real server groups
2
Real server group configuration is a three-step process:
• First, you must define the real server group.
• Once defined, you can associate one or more real servers with that real server group. Up to
four real servers can be associated with a real server group in a single command.
• You can then bind the real server group to a virtual server.
Although a real server can be associated with one-and-only-one real server group, each real server
group can be bound to multiple virtual servers.
Defining a real server group
To define a real server group use the server group-real command.
Virtual ADX(config)#server group-real sg1
Syntax: [no] server group-real real-server-group-name
The real-server-group-name variable identifies the name of the real server group.
The no option enables you to delete a real server group. If you delete a real server group that has
been bound to a virtual server, the Brocade Virtual ADX automatically unbinds all of the real
servers associated with that real server group. The real servers themselves are not deleted and
remain intact in the configuration.
Associating a real server with a real server group
Use the real-server command to associate one or more real servers with a real server group.
Each real server can be associated with one-and-only-one real server group. If you associate a real
server with a real server group that is already bound to a virtual server, the Brocade Virtual ADX
automatically binds the newly associated real server to the virtual server.
To associate up to four real servers with a real server group, enter a command such as the
following:
Virtual ADX(config-rsg-sg1)#real-server rs1 rs2 rs3 rs4
Syntax: [no] real-server real-server-names
The real-server-names variable specifies the real servers associated with a real server group.
The no option enables you to disassociate a real server from a real server group. If you disassociate
a real server from a real server group bound to a virtual server, the Brocade Virtual ADX
automatically unbinds the real server. Only those real server bindings that were particular to the
real server group are removed.
