it's full or half... otherwise it wouldn't let me choose

full duplex works great to the dsl modem - no collisions on e0/0.

full duplex to two different switches is causing a huge slowdown out of e0/1.



i wonder if it could be a layer 1 problem... will check cable that goes to main switch when i get a chance after everyone leaves.

could be vendor compatability issue.

are both switches from the same vendor?

debug the interface and see what comes up

You should throw that service policy on there right now anyhow.

Its not going to affect their web traffic, and would only help to optimize their upload queue/drops.

And yes, you would apply it in addition to the VOIP service policy that Bobby helped you with.

yeah i've got that up... after i verified the problems were with e0/1 on the full/half-duplex i applied the policies...

what's the best way to test this? i'd like to see the amount of traffic and what not laid out if possible, showing that the policies are working.

show policy-map int e0/0

post the output here and I will take a look to verify.

Looks pretty good in general, but does seem that you are going over your total 360kbps in voice at some point there.

May want to tweak it up just a bit more, but 171 drops out of 423k packets isnt really that bad.

adjusted it to 448 from 360 and cleared counters.

i'll check it tomorrow and see how we do there.



overall i think it's working...

switching cables to the switch on e0/1 didn't work... full duplex still won't work on that... so odd.

won't work hooked up to 2 different 10/100mbps switches.

Am I reading this right to show 4.7% of bytes are dropped ??? (330125 / 7025633) ?


Also, shouldn't Match: ip rtp 51044 0 show numbers other than 0? Is it not actually matching up udp port 51044, but it's just matching access-group 2 (permit any)?

EDIT: took out access-group 2 match since that was just giving all traffic priority, heh. I left only the ip rtp 15044 1 (correct port this time) and that is now matching data.

what kind of ethernet interface is it? is it on a WIC or built in?

classic 10MB ethernet ports are only spec'ed for half duplex, but we've made some 10MB ports that are not quite standard that will do full duplex, which is typically only seen on Fast Ethernet ports.

Let me know what kind of interface it's on. (maybe grab a show inventory or show diag) and i can figure out if that situation applies.

built-in. full-duplex works on e0/0 hooked up to the dsl modem. e0/1 doesn't work full-duplex (goes to about 1% of available bandwidth) hooked up to 2 different switches so far.

would it be worth it to assign a policy for inbound VOIP traffic, too... or would that not even do anything since i don't control it until it reaches the router ?

You dont need an inbound policy (unless you are maxing out your 10M ethernet interface. If you start seeing output drops on that interface, you may start considering a policy outbound on the lan ethernet interface.

An inbound policy on the wan interface would not do you any good though.

-- also, the change you made looks alot better now. I wouldnt expect any more drops to be seen on that router.

Do you have QoS on a remote site or anything? I imagine these voice calls are going to a remote location somewhere.

it's hosted PBX, so it goes to 1 place over the internet and i'm sure they do all they can to give voice priority... i know i've done all i can.

my limitation now is DSL latency / overall line quality.



(pkts matched/bytes matched) 19234/1403805
(total drops/bytes drops) 0/0




i think my problem now could be collisions on the LAN with not having full duplex... still working on that. i have a linksys/cisco 24 port switch i'm about to test hooked up to it.

Okay i just hooked up e0/1 to a Linksys SR224G ( http://www.linksys.com/servlet/Satellite?c=L_Product_C2&childpagename=US%2FLayout&pagename=Linksys%2FCommon%2FVisitorWrapper&cid=1159570515618 )

Full-Duplex still comes to a halt...


bad IOS version? bad port?

i'm thinking bad port, since the other ethernet port doesn't have the same problem.

i'm gonna switch e0/0 and e0/1 config and cable... see if full duplex doesn't work on exact setup switched.

i am also trying a new ios soon w/ ssh support.

yeah you probably bought a broken router off EBAY ... Happens all the time.

I may have an extra one lying around somewhere though if you want to buy it. I would give you a 30 day warantee

all problems fixed ... upgraded to a 2611XM with FastE ports, no collisions, no problems with VOIP, etc. just couldn't get full duplex to work on the 10mbit ports for the regular 2611.
