Re: [NANOG-LIST] Re: Graphing Peering
Well with mac accounting i've found that the results are not correct number they have to multiplied or something. I have a GigE and it has multiple peering sessions on it. Flowscan can't keep up, i have to export it in samples and that just defeats the purpose. I'm trying to find a way to graph indivual peers with totals. If there was a way to do it in perl i would... but i can't find the traffic on a per session basis. I'm running a cisco 12000 series router, with a current ios. I know juniper makes it really easy, but i have cisco :) Thanks everyone who has contributed. I really do appreciate it.

Hello,
Something like this would be possible with an Sflow stream if your ethernet device supports it. By parsing out the src/dst mac addresses you could at least visualize which MAC is using up most of your ethernet.

no i mean graph bgp sessions...
it's a single interface, and i want to graph every bgp session so i can see how much traffic i'm doing between each peer.

Anyone have any suggestions on graphing peering on a cisco router? I'm using mrtg and i did mac address accounting but the numbers are off.
do you mean how to graph traffic to each host on a lan..?
what platform do you have?

the ingress/egress linecards make a large difference in your stats collection efforts... so you might want to mention what they are so those that have tackled this before can better assist. -Chris

"ip accounting mac-address input" "ip accounting mac-address output" then collect "sh arp" and "sh int mac-accounting" to sync up with your bgp sessions and ips, and you're all set. - jared
