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 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/ ___ 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
Here is the further information that you have requested. I am using iperf unix client/server to test my speed. I have the same 45M limit if I try a bit torrent. I have a cisco 7200 router that is connected via a mvp copper to fiber converter. The t3s are bonded with an anda 2200. I have unbonded both t3s and they both get 45M over each circuit.

[c-nsp] MTU at Gb/sec transit and higher
I apologize if this is somewhat off-topic. I searched for this and found almost no information. I found this, but it's almost 10 years old and it seems like he gave up: http://staff.psc.edu/mathis/MTU/ 1. If I purchase GbE transit from a provider what size is the MTU likely to be? Is it still ~1500 bytes? 2. At any point closer to the core of the internet does the MTU step up from 1500 bytes to some larger value and are jumbo frames utilized? Or worse does the MTU step down from 1500 bytes? 3. What size MTU is used at (major) peering points? I am expecting the answers to all the above to be it's all ~1500 bytes but I want to confirm that. 4. Does most of the current Cisco gear used by NSPs support jumbo frame on GbE and faster interfaces? If anyone has any insight or comments I'd be happy to get them either on or off list. If off list please use the email below.

[c-nsp] Same VLAN in more than one MST Region
Hi everyone, I'm thinking of implementing MST instead of PVST+ in my network and is looking through the various Cisco docs. While the docs stated that a VLAN can only exist in one instance in a region, I've not come across a doc which says that the same VLAN cannot exist in more than one region. i.e. Region A, instance 0: Vlans 1 - 4094 Region B, instance 0: Vlans 10,20,30 Region B, instance 1: Vlans 40,50,60 Region C, instance 0: Vlans 100-200 Region D, instance 0: Vlans 100-200 All switches are in the same network. Would anyone be able to shed some light or experience on this? Thanks and best regards, ___ 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/
