Help Interpreting SNMP Output for Fibre Alliance MIB's

Oct 17, 2006 2 Replies

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.
