SUMMARY

MRTG wasn't producing any graphs for new switches we added and aggregate graphs were all kinds of jacked up. Some investigation ensued.

MRTG doesn't like @ symbols in communities. IXP Manager has no problem with it elsewhere.

STEPS TO REPRODUCE

Add a switch with an @ symbol in the community. Watch MRTG.

EXPECTED RESULTS

Normal MRTG graphs.

ACTUAL RESULTS

Member graphs were blank and aggregate graphs were jacked up.

IMPORTANCE

Yes, but in the short term I can work around it in changing the community used.
