Brocade licenses for optional Network OS features (Continued) TABLE 2
License Description
10 GbE Port Upgrade
• PORT_10G_UPGRADE
License function depends on the VDX 6740 model:
• For the Brocade VDX 6740 and VDX 6740T, this license adds 10 GbE ports in increments of
eight ports (8, 16, 24) per license. For Brocade VDX 6740, ports operate at 1 Gbps, 10 Gbps, or
auto-sensing mode and VDX 6740T ports operate at 100 Mbps, 1 Gbps, 10 Gbps, or auto-
sensing mode.
• For the Brocade VDX 6740T-1G, this license upgrades existing 1 GbE ports to 1/10 GbE
operation in increments of 16 ports (16, 32, 48) per license. VDX 6740T-1G ports operate at 100
Mbps, 1 Gbps, or auto-sensing mode. When upgraded with Port Upgrade license, 6740T-1G
ports operate at 100 Mbps, 1 Gbps, 10 Gbps.
40 GbE Port Upgrade
• PORT_40G_UPGRADE
License function depends on the VDX 6740 model:
• For the Brocade VDX 6740 and VDX 6740T, this license adds 40 GbE ports in increments of two
ports (2, 4) per license to provide four total ports.
• For the Brocade VDX 6740T-1G, as the switch ships with two 40 GbE ports, the license is
available in a single two-port increment to provide four total ports.
Licensing restrictions and considerations
This section lists the generic rules, restrictions, and considerations related to the software licensing:
• A license is tied to the unique LID of the blade or the switch for which the license was generated.
Therefore, a license can be used on one switch only. It cannot be used on any other switch.
• More than one license for multiple features can be installed per switch.
• Only one permanent or temporary license at a time can be in effect for a licensed feature.
• More than one trial license can be in effect at the same time, as long as each trial license applies to
a unique licensed feature.
• A trial license cannot replace or supersede a normal license.
• Licenses are not interchangeable between units.
• License management in Network OS v3.0.0 and later is supported only on the local RBridge. You
cannot configure or display licenses on remote nodes in the fabric.
Usage restrictions for time-based licenses
The following restrictions apply to all time-based licenses:
• Time-based licenses are always retained in the license database and cannot be deleted.
• Once you have installed a time-based license, you cannot change the system date or time.
• Other mechanisms for changing date and time, such as Network Time Protocol (NTP), are not
blocked. If you are using NTP to synchronize the time between your network devices, including
switches or enterprise-class platforms, do not attempt to change the system date and time when a
time-based license is installed.
Configuration management considerations
Licenses are independent of configuration files and are therefore not affected when you make changes
to a configuration file or restore the default configuration. The only exceptions are Dynamic POD
configurations. When you download a configuration from another switch or you restore the default
