Multiple port binding

NOTE
The default port (a port the Brocade Virtual ADX automatically configures on all real and virtual
servers) and the source IP application port do not support multiple port binding.
Specifying the number of multiple port bindings available
Direct binding of multiple ports is enabled by default with the default value for the number of
bindings allowed as determined by the license that is active on your system. Use the system-max
l4-multi-binding command to change the number of multiple port bindings available or disable
multiple port binding.
Syntax: system-max l4-multi-binding new_max
The new_max variable identifies the number of multiple port bindings that can be created. The
minimum, maximum and default values are determined by the license that is active on your
system. For actual values associated with your license, refer to the Brocade Virtual ADX Licensing
Guide. If the new_max value is set to 0, support for multiple port binding is disabled.
Whenever you specify the number of multiple port bindings, you must restart the system if you
change the new_max value to a different non-zero value. If reloading the system is not an option,
you must remove all additional multiple port bindings before changing the new_max value.
The show server resource command displays the number of multiple port bindings, as shown in the
following example.

The number of configured server ports and configured multiple port bindings can be captured by
an SNMP trap when a certain threshold is reached.
In the output of the show server bind command, each additional binding is displayed with a + sign
appended to it.
