Loopback Port Type

  • 1.  Loopback Port Type

    Posted 05-15-2015 08:30 AM

    I have a MPX 110 switch connected to port 5 on 2 brocades (the 2nd being the failover).

    I just noticed on the 2nd brocade the port type states Loopback->5. The 1st Brocade shows L-Port.


    Port#      Port Id      Port Name         Port Type          Speed (Gb/s) Port Status Health 
    5(0x5) 0x0B0500 MPX110-FCIP       L-Port                 N2                   Online     Unmonitored 
    5(0x5) 0x150500 MPX110-FCIP    Loopback->5         N2                   Online     Unmonitored  


    What is this loopback type referring to? Is there something I need to configure or change on the port side?

    thank you!

    Thank you.

    so I need to execute the following commands on my mpx110 switch to configure the ports where MPX110 is connected as Gport and enable ISL mode?


    B-Switch# switchdisable
    B-Switch# iodset
    B-Switch# aptpolicy 1
    B-Switch# portcfgislmode 5,1 (5 being the port the FCIP gateway is plugged into)
    B-Switch# portcfggport 5,1
    B-Switch# switchenable


    Do I do this on both my mpx110 locations (local and remote) or just local?

    thank you.

    I have portdisabled and portenabled on my brocade and the status went from loopback to In_Sync however on my mpx110 it still states

    FCIP Link Status                              Down


    what could the issue be?

    In this case, I would recommend to contact product vendor.
