Ports on Demand
18
For the embedded switch modules, the Dynamic POD feature detects and assigns ports to a POD
license only if the server blade is installed with an HBA present. A server blade that does not have a
functioning HBA is treated as an inactive link during initial POD port assignment. For the non-server
blade switches, the dynamic assignment occurs when an attached Fibre Channel link transitions to
the “link active” state.
The Dynamic POD feature assigns the ports to the POD license as they come online. Typically,
assignments are sequential, starting with the lowest port number. However, variations in the
equipment attached to the ports can cause the ports to take different amounts of time to come
online. This means that the port assignment order is not guaranteed.
If the switch detects more active links than allowed by the current POD licenses, then some ports
will not be assigned a POD license. Ports that do not receive a POD assignment have a state of
No Sync or In Sync ; these ports are not allowed to progress to the online state. Ports that cannot be
brought online because of insufficient POD licenses have a state of (No POD License) Disabled .
You can use the switchShow command to display the port states.
Displaying the port license assignments
When you display the available licenses, you can also view the current port assignment of those
licenses.
Use the following procedure to display the port license assignments:
1. Connect to the switch and log in using an account with admin permissions.
2. Enter the licensePort -- show command.

Enabling Dynamic Ports on Demand
If the switch is in the static POD mode, then activating the Dynamic POD will erase any prior port
license assignments the next time the switch is rebooted. The static POD assignments become the
initial Dynamic POD assignments. After the Dynamic POD feature is enabled, you can customize
the POD license associations.
Use the following procedure to enable Dynamic Ports on Demand:
1. Connect to the switch and log in using an account with admin permissions.
2. Enter the licensePort -- method command with the dynamic option to change the license
assignment method to dynamic.
