Errors On Multilink Interface

In an older version, that multilinkinterface came up at something like 100MB, whichwasn't a problem, but then for some reason theychanged it to coming up at like 64k or somethingweird like Please type your message and try again. 3 Replies Latest reply: Jun 14, 2013 12:54 PM by Chandan Singh Takuli Multilink Errors on 2911 usborderpatrol Jun 11, 2013 10:45 AM I'm As well, the CEF with round-robin packet distrobution might be a better solution than MPP, but we'd need to examine it more in depth first.Pervis that's an interesting thought. http://networking.ventrefamily.com dieselboy Post Whore Posts: 2747 Joined: Tue Aug 05, 2008 6:36 am Certs: CCNP, CCNA Voice, SMB Select, Linux+ Re: Input errors on Multilink but not physical Serial's Wed Aug http://radionasim.com/errors-on/errors-on-laptop-trojan-horse.php

Google around for TCP window scaling for more info.

The ppp multilink group looks like it is summing the bandwidth correctly- try a show ppp multilink to see what info is on the multilink ppp int.I don't get it... It seems to me to be a reasonable IOS, but I might still check the caveats. I doubt > they have any affect, but I'd get rid of them.

Can anyone point out anything wrong with this chain of thought? The transmit and receive stats are rather puzzling to me. Could this kind of disparity in the time that the rate is recalculated occur and explain why the numbers are different? · actions · 2010-Feb-16 1:20 pm · MrTwisterPremium Memberjoin:2003-09-27Hilliard, OH

It's sprint there, so even though the lines are AT&T, I'm going to end up talking to sprint about it - and they are generally clueless.quote:They are all in correct multilink Actually it'll directly effect it.IF the problem is that the MTU on ethernet is 1500, and the MTU on the MPP is 1500, and i'm getting frame fragmentation due to the perhaps I should have some sort of queueing happening?
