Multiple port binding

2

Using a start-index variable begins display at the record specified where the first record has a value
of 0. In the following example, the start-index value of 2 is used on the same port-range displayed
in the previous example.

To display a list of port ranges with a name that starts with a specified prefix, issue the following
command.

Virtual ADX(config)#show port-range starts-with pr

Syntax: show port-range starts-with prefix

The

describes the information in the output.

Multiple port binding

Multiple port binding allows you to bind one real server port to multiple virtual server ports.

The Brocade Virtual ADX supports two methods of associating a real server TCP or UDP port to
multiple virtual TCP or UDP ports (VIPs): direct binding of multiple ports and port aliases.

Direct binding of multiple ports enables to you to associate a real server TCP or UDP port
directly to multiple virtual TCP or UDP ports. Using this method you do not need to configure
additional alias ports for real ports or virtual ports in order to bind a single real server to
multiple virtual servers; nor are alias ports needed to bind a real server to multiple virtual ports
on a single virtual server.

Port aliases bind a real server TCP or UDP port to multiple port aliases, which are bound to the
virtual ports.

Although the Brocade Virtual ADX supports both direct binding of multiple ports and port aliases,
the two methods cannot co-exist for the same real port or virtual port.
