7. Bind the alias ports to the real servers on the virtual servers.
Virtual ADX(config-vs-vs2)#bind http rs1 8081 real-port 81 rs2 8082 real-port

Syntax: bind virtual-port real-server-name alias-port [real-port real-port-num]
NOTE
Alias ports should be treated like regular ports and should have the same server ID and group ID.
Binding a real server port to multiple VIPs for port translation
You can bind a real server port to multiple VIP ports with or without port translation. Port
translation is useful in cases where different client groups require different VIPs.
The real-port option has been added to the existing port virtual subcommand.
Syntax: [no] port tcp/udp-port real-port real-server-port-to-use
NOTE
This feature takes precedence over the no port port translate virtual subcommand.
In the following examples, notice that alias port 8081 is defined for binding between the real server
and virtual server. The alias port and the real-port work together.
To bind one real server port to multiple VIPs (vs1 and vs2), enter commands such as the following.
. To bind one real server port to multiple virtual ports of one VIP, enter commands such as the
following.
