Is the ExtendedEdge Core PID functionality available with newer FOS (6.x), so that my legacy ISL-Linked switches may still interact with 4/32 switches (configured with PID 2), when these 4/32 will be upgraded to FOS 6.4 ?
Thanks for your help

According Release Notes i.e. till 6.4.1, are not restriction listed about PID , excepted the restriction in the Table Notes.
If you are satisfied with the responses please mark as 'Answered'.
If not, just let me know I can see to get more info.
I would appreciated if you rate the threads.

Thanks a lot ABBA-SYSTEMS : I am asking this because according to the FOS 6.2 Admin Guide provided but HP (c01660048.pdf, P. 524), it does not seem to be possible :
HP StorageWorks switches employ the following types of PID formats:
• VC encoded is the format defined by the HP Fibre Channel Switch 8 and 16. Connections to these
switches are not supported in Fabric OS 4.0.0 and later.
• Native was introduced with the HP StorageWorks SAN Switch 8 and 16, and HP StorageWorks SAN
Switch 8-EL and 16-EL. This format supports up to 16 ports per switch.
• Core is the default for HP StorageWorks 4/8 and 4/16 SAN Switches, HP StorageWorks 8/8 and
8/24 SAN Switches, HP StorageWorks SAN Switch 2/8V, HP StorageWorks SAN Switch 2/16V, HP
StorageWorks SAN Switch 2/32, HP StorageWorks SAN Switch 4/32, HP StorageWorks 4/64 SAN
Switch, HP StorageWorks SAN Switch 4/32B, HP StorageWorks 8/40 SAN Switch, HP StorageWorks
8/80 SAN Switch, HP StorageWorks 400 Multi-Protocol Router, and HP StorageWorks SAN Director
2/128, HP StorageWorks 4/256 SAN Director, HP StorageWorks DC SAN Backbone Director, and HP
StorageWorks DC04 SAN Director platforms. This is the recommended format for HP StorageWorks
switches and fabrics. It uses the entire 8-bit address space and directly uses the port number as the
• Extended edge is a format that generates the same PID for a port on switches with 16 ports or less as
would native PID format, but also supports up to 256 ports per domain. It should be used only in cases
where you cannot upgrade devices to dynamic PID binding and you absolutely cannot reboot your
Extended edge PID is supported in 3.1.2 and later and 4.2.0 through 5.3.0.
Extended Edge is not supported on any switch with Fabric OS 6.0.0 or later.
In addition to the PID formats listed here, interoperability mode supports additional PID formats that are not
discussed in this guide.
So, if you could find some more information about it, or if somebody already built such a mixed-switches architecture using newer FOS, I would be very interested.
Thanks again for your help

I know this. the FOS Admn Guide sayed:
--->>> Extended Edge is not supported on any switch with Fabric OS 6.0.0 or later.
but not say
Switches with Extended Edge can not Partecipate in the same Fabric.

OK, thanks ABBA-SYSTEMS
If it is not supported by HP, then I'd better avoid this PID value...
Did you also find this information clearly stated somewhere in Brocade manuals ? If yes, could you send me the document reference ?
Thanks again for your help

Extended Edge is not supported by Fabric OS 6.1 and later releases.
If a fabric runs in Extended Edge mode, switches cannot be upgraded to 6.1 and above.
Because PID format is a fabric-wide parameter, any switches that run Fabric OS 6.1+ (always Core PID) will not join an "Extended-edge" fabric.
