    What is the purpose or function of the portifid in the output of portshow versus portid?

    Hello,

    this port interface index should be used for FSPF routing.

    Could you please tell me where can find the more detailed documents about the difference between portifid and portid?

    Hello,

     

    this is not documented in any of Brocade guides, please refer to FC standard documents to get more info.

    about portifid, please refer the FOS Admin Guide, here from v8.2.1 page 76

     

    Port Identification by Port Area ID
    The relationship between the port number and area ID depends upon the PID format used in the fabric. When the Core PID format is ineffect, the area ID for port 0 is 0, for port 1 is 1, and so forth.
    For 32-port blades (FC16-32), the numbering is contiguous up to port 15; from port 16, the numbering is still contiguous, but starts with 128. For example, port 15 in slot 1 has a port number and area ID of 15; port 16 has a port number and area ID of 128; port 17 has a port number and area ID of 129.
    For 48-port blades (FC16-48, FC32-48), the numbering is the same as for 32-port blades for the first 32 ports on the blade. For
    ports 32 through 47, area IDs are not unique, and the port index should be used instead of area ID.
    For the 64-port blades (FC16-64), the numbering is the same as for 32-port blades for the first 32 ports on the blade. For ports 32
    through 63, area IDs are not unique, and the port index should be used instead of area ID.
    If you perform a port swap operation, the port number and area ID no longer match.
    To determine the area ID of a particular port, enter the switchShow command. This command displays all ports on the current (logical) switch and their corresponding area IDs.

    this is adressing for PortID not not for PORTIFID which should belongs to port interface ID.

    I am so embarrassed and inattentive that I still do not radically understand the difference between the portifid and portid!
    And I must thanks to Marian for correcting some explanations!
