Help Interpreting SNMP Output for Fibre Alliance MIB's

    Hi,

    My apologies if this isn't the right group. I have a Cisco 9020 fibre
    switch connecting my EMC SAN components. I'm trying to measure
    throughput on the interfaces for the switch using SNMP for my network
    monitoring system.

    If I do an SNMP walk on the FIBRE-CHANNEL-FE-MIB'S, I see some OID's
    that I'm not sure how to interpret:

    For example, for port 7:

    ..1.3.6.1.2.1.75.1.4.3.1.3.1.7 (fcFxPortC3InOctets for port 7 on the
    fiber switch)
    ..1.3.6.1.2.1.75.1.4.3.1.4.1.7 = (fcFxPortC3OutOctets for poort 7 on the
    fiber switch)

    The docs say the following about fcFxPortC3InOctets

    "The number of Class 3 frame octets, including the frame delimiters,
    delivered through this FxPort to its attached NxPort. "

    Here's the oupout for the ports 1-7:

    OID: .1.3.6.1.2.1.75.1.4.3.1.3.1.1
    Value: 2852287863

    OID: .1.3.6.1.2.1.75.1.4.3.1.3.1.2
    Value: 948614975

    OID: .1.3.6.1.2.1.75.1.4.3.1.3.1.3
    Value: 97041284

    OID: .1.3.6.1.2.1.75.1.4.3.1.3.1.4
    Value: 127562014

    OID: .1.3.6.1.2.1.75.1.4.3.1.3.1.5
    Value: 3921620920

    OID: .1.3.6.1.2.1.75.1.4.3.1.3.1.6
    Value: 3936442885

    OID: .1.3.6.1.2.1.75.1.4.3.1.3.1.7
    Value: 3816608435

    Can I interpret this as the number of incoming bytes?

    Is there a better way to get throughput information using SNMP?

    Any information would be helpful.

    Thanks

    Yes, it appears so ...

    Hey Bernie,

    Thanks. Any idea on how I can convert this to a number that is
    undserstandable to humans? I'm looking for bits per second or
    something similar. These numbers are pretty big and can't be bytes per
    second. They must be total bytes.

    I couldn't find an OID that returned transfer rate in bits persecond.
