Metro Ethernet

Post by kkriegel »

Metro Ethernet is growing fast. As an ISP, I have ONE interface that is connected to 15 customers. I have access to the router interface at my end, but not always at their end.

I would like to be able to graph each user seperately. I have raised the question of "how-to" on the forums a couple of times. To date I have received zero responses.

(I see one message about barracudas, and another about aggregation...)

As vlans on a trunk? Do you have an IP interface per customer on your side? (probably not) Does your router show a sub-interface for each customer? What platform are you using? VPLS? EoMPLS? Something else?
Weathermap 0.98a is out! & QuickTree 1.0. Superlinks is over there now (and built-in to Cacti 1.x).
Some Other Cacti tweaks, including strip-graphs, icons and snmp/netflow stuff.
(Let me know if you have UK DevOps or Network Ops opportunities, too!)

The setup is very straight forward layer 3. I have a router interface with a fiber connection to my providers "cloud". The IP is mine, not the providers. The provider drags a fiber from the "cloud" to my customer. The customer connects their router and assigns an IP address from the same subnet and we are communicating. There is plainly some layer 2 magic going on inside the providers cloud, but to my customers and I, it is just an ethernet LAN. The only limit to the number of customers I can have on that same interface is the subnet. In my particular instance, I have 29 hosts on that interface (besides myself). Once they hit my router, I am their gateway to the internet.

Obviously I have access to my interface, and can graph it. But I do not have access to all of the customers so the graphing has to take place on my end. I am trying to graph how much of my interface is used by each customer.

sflow or netflow

Sounds like you should use something like sflow or netflow if your router supports it to get the data.

See something like this for sflow:

Products that use sflow:

As long as you have the IP addresses of your customers it shouldn't be too hard to get the data from sflow or netflow(I have no experience with netflow myself I don't use cisco). From there you can feed the data into cacti via scripts and stuff. Or look at another product such as ntop or something.

Some devices support private MIBs featuring capabilities which come close or perhaps match exactly. Please contact the vendor. If there ARE private OIDs, fine.
