<div dir="ltr"><font color="#000000" size="2" face="Tahoma">I have setup mrtg to monitor traffic for a specific Ethernet interface on a Cisco Catalyst 6509 that connects two campuses over a fiber WAN link. The third party fiber provider says they are giving
us 100Mbps across the fiber, but we need to verify what we are actually getting. I have come to realize that simply monitoring the WAN interface gives me a nice graph and actual kB/s (or MB/s) data passed, as shown below; however, the percentages are based
on my Maxbytes value that is based on what the ISP says we are getting (100Mpbs or 12.5MB/s). In other words, I can change the percentages by adjusting MaxBytes. Is there any way to use mrtg to verify the available bandwidth over the WAN, or do I need a
different tool?</font></div>
