Configuration upload and download considerations for FA-PWWN
The configuration upload and download utilities can be used to import and export the FA-PWWN configuration.
ATTENTION
Brocade recommends you delete all FA-PWWNs from the switch with the configuration being replaced before you upload or
download a modified configuration. This is to ensure no duplicate FA-PWWNs in the fabric.
Security considerations for FA-PWWN
If security is a concern, ensure that only authorized users can configure FA-PWWNs. Device authentication and DCC policies provide
additional security between the switch and the server.
The FA-PWWN feature can be enabled only by authorized administrators. Thus, existing user-level authentication and authorization
mechanisms should be used to ensure only authorized users can configure this feature.
If you are concerned about security for FA-PWWNs, you should configure device authentication. You can use authentication at the
device level to ensure security between the switch and the server. Refer to Device authentication policy on page 230 for information
about configuring device authentication.
You can also use the Device Connection Control (DCC) policy to ensure that only an authorized physical server can connect to a specific
switch port.
NOTE
When creating the DCC policy, use the physical device WWN and not the FA-PWWN.
If you use DCC, a policy check is done on the physical PWWN on the servers. In the case of an HBA, the FA-PWWN is assigned to the
HBA only after the DCC check is successful. Refer to DCC policy behavior with Fabric-Assigned PWWNs on page 224 for additional
information.
Restrictions of FA-PWWN
The FA-PWWN feature is not supported with some Fibre Channel fabric features.
FA-PWWN is not supported for the following:
∙ FCoE devices
∙ FL_Ports
∙ Swapped ports (using the portswap command)
∙ Cascaded Access Gateway topologies
∙ FICON/FMS mode
∙ With F_Port trunking on directly attached Brocade HBAs or adapters
