ONS 15454 OIDs and graphing

Anyone else graphing data from your 15454's? I'm looking into what OID's would be good. For example, I'd like to have a historical graph of the incoming power levels in my transponders.

Re: ONS 15454 OIDs and graphing

We're graphing some data. The CERENT mibs have optical power levels for some of the interfaces at:



For some reason you have to divide by 10 to get dBm, though.

And that's all we've been graphing so far, but I want to do more. We'd love to do span loss but I haven't found an OID for it and I figure on adding FEC/UFEC and other PM values which I just haven't gotten to yet.

I'm trying to figure out how to get levels for OC192 cards w/o success so far (it took forever to find the levels in CTC, too!)

Re: ONS 15454 OIDs and graphing

Thanks for the information - I haven't done too much with it yet, but send me an email sometime if you'd like to collaborate on anything with regard to this.

Here is some info that Cisco sent me on how to correlate the OID's to the cards in the ONS:

Here is how you correlate OID's:

Calculating the STS index.

Slot 1 has a base value of 4096. To get the base value of any other slot multiply 4096 by the slot number. (slot 2 is 8192).

The card in the slot is the slot value plus 1. So a card in slot 2 has a value of 8193.

An STS in a slot is the STS value plus the card value. So the fourth sts on an OC48 card in slot 2 would be 8193 + 4 = 8196.

Here's an OID...


4096 is the slot index. 4097 is a card index.It is not a valid interface index.Valid interfaces indices for slot 1, generally start at 4098. But the numbering mightbe different if there are PIMs/PPMs.

So 4098 is the 1st STS1 on slot 1 and 8194 is the first STS1 on slot2.

Similarly valid indices for slot2 will generally start at 8194.

(8192=slot, 8193=card)

So slot12 => 4096 * 12 = 49152 = slot index => sts1 index on slot 12 is 49154.
