Good day, we are getting delay when trying to access web, at least 5 second delay when going to websites. speedtest varies from 1.6 to 5.7mB. Oracle Database long transactions are dropping and needing to be restarted.
Should be a 7MB DSL.
Are the BW 5000 Kbit/sec, RxBW 7000 Kbit/sec, DLY 20000 usec, correct? I read these are only QOS related, but no QOS on device.

I see that too, is the ATM0 interface related to the dialer interface? I see bandwidth on Dialer 1 as 5000kbits, why does the ATM interface have low BW? From my undestanding the dialer interface is virtual to get PPPoE going. And the ATM0 is the physical interface? Thanks for the feedback.

What model is your router?
You may need to configure traffic shapping. Notice on the ATM interface you have output drops. This means that the remote end device of the ATM interface is dropping packets.
01-17-2014 01:38 AM
Coleman,
I cheked the configuration and it seems like your active bandwidth is somewhere close to 512kbps.
VCIs per VPI: 1024,
Max. Datagram Size: 4528
PLIM Type: ADSL - 512Kbps Upstream, DMT, TX clocking: LINE
1850 input, 2 output, 1293339 IN fast, 1094027 OUT fast
Avail bw = 512
Config. is ACTIVE
On the dialer interface:-
Available Bandwidth 3750 kilobits/sec
5 minute input rate 515000 bits/sec, 116 packets/sec
5 minute output rate 402000 bits/sec, 105 packets/sec
On virtual access interface:-
Output queue: 0/40 (size/max)
5 minute input rate 540000 bits/sec, 133 packets/sec
5 minute output rate 436000 bits/sec, 125 packets/sec
THese 3 results evidently showed that your net bandwidth asllowed acording to the Telco and according to the line rate is not more than .5 megs.
We can enable ATM layer traffic shapping or can enable policing under the dialer interface to privent this.
Please try the following command:-
Policy-map TEST
class class-default
police rate percent 99
Please make sure you change the bandwidth statement under the dialer as 512kbps , else calculation will be done according to the current bandwidth command which is manually 5000 kbps.
interface dialer 1
bandwidth 512000
Apply policy to the dialer:-
interface dialer 1
service-policy out TEST
Once this policy will be configured please take the output of :-
show policy-map interface dialer 1
It will show you the offered rate and drop rate , drop rate will be observed once policer will start polcing above 512.
NEXT ACTION:-
1. Please provide the above outputs (show policy-map int dia 1)
2. show interface dia1
3. Change th hold-queue valus under the dialer to 100 (hold-queue 100 out)
4. Confirm with the telco about the line rate and allowed bandwidth.
_THnak you
Ashish

Here are the results, I dont see any current drops, may have to check it later. Why would the DSL interace ever be at 512k? Is one interface for upstream vs downstream..? I know I have heard of 512 k upstream and 5MB download for DSL. Please clarify for understanding. thanks.

This would be your downstream speed 5760 and your upstream is 512k.
You could check with your telco if they have a dsl profile with better upstream.
