  • 1.  Custom cert for Cisco MDS Fibre-channel switches

    Posted Nov 22, 2022 10:40 AM
    Hi: Has anyone built a custom cert for Cisco MDS Fibre-channel switches?
    I've searched the factory certs and it all appears to be Brocade orientated - unless I've missed something.
    It's the fibre-channel throughput, signal strength, errors that I'm interested in.  The factory certs cover the Ethernet connectivity.
    Thanks.

    Hi Glenn,

    you can open a case in support asking for the certification, or you can certify by yourself.

    Let me know if you need help

    Reviewed this with Jose's assistance.  I don't like the existing Cisco Fabric Channel Port VC as it's mapped to the Alternate Interface MF - unlike the Brocade VCs which map to Fibre Channel MF.  Reworked the Cisco fibre VC, using Fibre Channel (although I may have to extend this and fix what appears to be a mistake in Discards).
    However, using this brings me to my question: I'm *fairly* sure that 'normal' network interfaces are not polled by DCs unless their Status is Up, while my custom VC seems to be polling all IF instances.  Interestingly Cisco describe the FC-FE-MIB as an extension of MIB-2 and they carefully use the same Instance information as the ifTable and fcFeMIBObjects (1.3.6.1.2.1.75.1).
    Is there a convenient way to update my custom vc to stop the DC polling IFs that are down (perhaps add a second MIB to the VC XML)?
    Or is polling more explicitly controlled by the VC?
    Thanks.

    Hi Glenn,

    DC polls the discovered items according to the VC. You have 2 ways to avoid polling some items:

    1) Not discovering them:  this can be done using the Filter section in the VC
    2) Filtering them in the Monitoring Profile using a filter expression on the MF attributes (take a look at Network Interface Monitoring Profile)

    Note: attributes available to create filters mush be enabled in the MF (see Interface MF for reference) 

    I do not see Fibre Channel MF has an attribute like Interface MF to hold the Administrative Status

    Regards
