Re: [c-nsp] Bonded T3 Bandwidth issue
The Anda equipment is used to bond TDM / SONET based circuits (DS1 / DS3 / OC3) and provide an Ethernet circuit across. The provider he is using would have an Anda 2200 on their side, and one at his end. (That is both ends of the bonding) His hand-off from the Anda would be RJ45 ethernet, directly into the 7200. It seems that the provider is at fault here, based on the bonding to get 90Mbps (minus overhead) is done on their end. The anda boxes have multiple groups, so it is possible they do not have the DS3 circuits in the same group on the configuration of the Anda box, which would provide only the throughput of a single DS3, since only 1 would be mapped to his ethernet hand-off. Another thing to consider is that the Anda would need to be a 2212 (can you verify it is) to do the bonding, because only that box has 2 DS3 ports on the WAN side. It is also an option to configure this as protection where only 1 DS3 would be used at a time, and the other would be used if one were down. You can have the provider verify that configuration. Hope to help.

Re: [c-nsp] Bonded T3 Bandwidth issue
The anda is a metro E box. Are you bonding them and then turning the whole thing into ethernet? Also, how are they bonded? Are you running ml-ppp between the anda and the cisco? Doesn't it seem likely that the Anda box is the one doing the bonding? I see there is a 2212e model that has two DS3 wan interfaces. I would expect the fastE interface on this to be facing the cisco7200, which would take the cisco out of the bonding role. -mark ___ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
Re: [c-nsp] Bonded T3 Bandwidth issue
The 2212 DS3\E3 does the bonding and as you have stated the 7200 is out of the bonding role. Could this have anything to do with the negotiation between my fiber to copper converter and my router? This is what my wan provider is telling me. On Fri, Feb 25, 2011 at 09:02, Mark Kent m...@noc.mainstreet.net wrote: The anda is a metro E box.

Are you running ML-PPP between the anda and the 7200? If not it seems like the Anda thinks it has a big 90M pipe and the 7200 thinks it has two seperate (or one single) DS3. Bonding can only happen between two boxes speaking the same language.

Re: [c-nsp] Bonded T3 Bandwidth issue
How have you bonded the DS3? Typically load balancing on cisco boxes are per session so you will never get over anything beyond the speed of the link (45Mb/s). In order to do something beyond that, you need to load balance per packet. I wrote up this paper in '96 about how to do this with DS1s. The same applies with DS3s http://www.lns.com/papers/netload/ Tim on 2/23/11 7:40 PM Lawrence said the following: I have a bonded T3 that I have never been able to get over 45mbs.
