No, that's the OID for a table that contains the OID's you really want.
If you walk the table, you'll seee that sysTrafficMeter.1
(220.127.116.11.18.104.22.168.22.214.171.124.2.1) is what you want to measure with a Sup II, or
sysTrafficMeter.1 .2 .3 and .4 for a Sup III.
[N.B. These values don't exist on a 6500 or 4000/SupIII]

Unless cfgmaker has changed drastically since I last dug under the hood
(possible, it's been a couple of years) that won't do a thing. What you
need to do is edit your config file and create a new target that points to
1. Since the LoadMibs: directive is fraught with danger when using cisco
mibs (You have to reference a half dozen SMI and TC files to get all of the
dependencies right, get them all in the right order, and make certain they
are all version 1 mibs. ) I edit the oid-mib-cache.txt file (should be in
your WORKDIR) to get a nice text representation. Add a line:
2. Create your targets. I normally create a separate file for this sort of
thing, call it 5500bus.cfg or some such. Don't forget to use 2
OID/Instances per target!
Target[5500systembus]: sysTrafficMeter.1&sysTrafficMeter.1 at public:184.108.40.206
... all of the other pagetop, legend stuff...
sysTrafficMeter.2&sysTrafficMeter.2 at public:220.127.116.11
3. Then edit your main mrtg.cfg file and include the file you created
When you next restart mrtg (if running in daemon mode) or at the next cron
interval (if running in cron mode) the new targets will be processed and
your database/log/graphs/whatever will be generated.
