Cisco 878 GSHDSL line rate
I have had a problem recently with an 878 using SDSL.
I recently lost connection to the device after a thunderstorm and assumed either a tail problem or a blown modem.
After several tests by BT the line passed as clear and after changing the 878, there was still no connection.
Reviewing my RANCID configs for the past 6 months shows that the config on the Controller DSL 0 changed over time. I originally set the line rate to auto, which was lated changed to hard code 2304k. This I have no problem with....unfortunately thats not the end of it.
The latest config (which was applied to the new router) shows the line rate at 1152k. When I double checked that yesterday, it had changed to 576k. Now, there has been no outside intervention, only I have access. The logs show nothing to prove that anything changed.
I have fixed the issue by resetting the line rate to auto, but what I need to know or understand is how has this changed without my intervention. This is not a negotiated rate as far as I was aware.
I would appreciate any help. Thanks
The only thing that I can think of is a software glitch. I cannot compare the startup config but considering the original router was rebooted several times and the line rate came back as 1152, I must assume that the startup had been altered as well.
I obviously need to find a cause for this for 2 reasons.
1/ I need to write a report on this
2/ To stop me from going mad
Cheers

Cisco 878 router for ADSL connectivity
Hi All,
I got a Cisco 878-k9 G.SHDSL router. I am trying to configure to get connectivity to my Service Provider.
Earlier i have configured Cisco 877 router serval times. But Cisco 878 for the first time. There is a DSL
controller in 878 rtr. I think i m missing something somewhere.

Hello everybody,
I would like to learn more about Cicso hardware, and the best way is to try and play with the hardware.
I have a Cisco 878 router, we used this router for an Internet Access connection.
I think the best way is to reset the router to it's default factory settings and upgrade the firmware before I start setting up the device.
I have an Ip-address, but telnet and ssh are not possible.
So I have a few questions, and I hope you guys can help me with this:
a. how can I reset the router?
b. how can I flash the firmware?
c. how can I setup the Cisco Router?
I would like to use the router for the following purpose: VLAN routing with two 3COM Layer 2 switches.
And I would like to setup the Cicso Router to get an IP address from my Cable Modem through ethernet, is this possible?
Because I know this model is for an symmetrical High-Data-Rate DSL (G.SHDSL) (4-wire), 4-port managed switch!!!
Configuration on the switches:
- LinkAggregation: Port 25:
- VLAN1 - Port 1 (managed)
- VLAN10 - Port 2-11 untagged, AL1 tagged
- VLAN11 - Port 12-24 untagged, AL1 tagged
The switches are connected from port 25 on switch 1 and port 25 on switch 2, the devices on VLAN10 Switch 1 can communicate with the devices on VLAN 10 on Switch 2, but routing between VLAN10 and VLAN11 is not possible.
So I would like to use the Cicso Router for the routing between the VLANS, is this possible?
If yes, is it possible to configure which traffic is possible between VLAN10 and VLAN11?
For clients it must be possible to connect to devices in VLAN10 and VLAN11 and Internet.
IP configuration:
VLAN1: 192.168.100.0/24
VLAN10: 192.168.1.0/24
VLAN11: 192.168.2.0/24
Client in VLAN 10 while have a static IP-address or while have an IP-addreess through DHCP, can DHCP be done by the Cisco Router?
I hope you guys have a good picture, and I hope to get some answers to get started.
Kind regards,
Martin.Hello everybody,

Hi..
Any idea if the 4 port 10GE card WS-X6704-10GE runs at line rate for each port ? Can we get approx 40Gbps throughput out of this card ?
Eng WeeHi Eng wee,
The 4 port 10 Gigabit Ethernet interface module is CEF720 based and communicate using 40-Gbps connections to the integrated 720-Gbps switch fabric of the Supervisor Engine 720.

Line rate always changing / Hub resetting itself
Hello
For the past 6 or 7 months we have seen dramatic fluctuations in our Broadband download speed. This change always comes about as a result of our our Home Hub 4 seemingly restting itself: we have normal internet use with a blue light on, but then the Hub will flash orange for a while and come back with a blue light. There is no pattern regarding the time of day; it's completely random.
I've been informed that a resetting connection will only inform the exchange that there is a problem, thus prompting the "IP Profile to be reduced" to make things stable. Surely then this isn't supposed to be happening?
There was a time when we would always get around 2.7 - 3.3 Mbps line rate, which is the best we could expect for our area and the distance from the exchange. The download speeds associated with that were good enough for us, but we can never seem to get that now.
The Event Log will report the process described above as: 'Failed to Resolve Host' and, once the connection is re-established, the line rate will usually be lower than it was before. As an example, a line rate of approx 2.3 Mbps will drop to about 1.3 Mbps. Sometimes this process will return a slightly higher line rate!
This happens approximately once every day, but the line rate is never the decent 3 Mbps we used to get...Sometimes I get lucky by manually resetting the Hub and the line rate will be 2.5 Mbps...but it isn't long before it resets itself and, again, we have about 1.2 Mbps.
Current event log:
12:24:27, 18 Sep.
( 97.940000) DSL noise margin: 5.90 dB upstream, 6.00 dB downstream
12:24:26, 18 Sep.
( 96.910000) DSL line rate: 934 Kbps upstream, 1315 Kbps downstream
12:24:11, 18 Sep.
( 81.000000) CWMP: session closed due to error: Could not resolve host
In the last month there was a small amount of noise on the telephone line (we were looking into it but it appears to have gone), but this line rate fluctuation started long before then anyway. Phone call with the Telephone department team told me there appears to be no problem with the line. We have also had 3 different Hubs during that time, so it isn't a Hub issue. Filters in place and Master Socket is in use. Using the test socket yeilds same problems.
Further questions if anyone is able to answer them:
Besides interference from noise, is there a good reason for the Hub to go through this process and force lower speeds upon us? Is the exchange throttling us or something?
For a period last year we were getting 380 kB/s in a speed test and that was fine to use because it matches the line capabilities that we have always been quoted. I don't understand why we can't have a similar speed now. We don't even get > 300kB/s during off peak times. Is it normal for our DL speed to now be always be about 180 kB/s? We were told during our recent re-contract that there is no longer any capping.presumbly the previous stats were from the test socket as new stats are just the same

just wondering what determines your line rate, ive come from having Virgin Media fibre optic, i know very little about ADSL
my connection is currently:
DSL line rate: 912 Kbps upstream, 8375 Kbps downstream
DSL noise margin: 5.90 dB upstream, 6.10 dB downstream
is it ever likely to change ?on Exchange SAINT HELENS is served by Cabinet 20

Line rate is higher than attainable rate!
I've been on Infinity for 3 or 4 months now and have had consistently a BT profile of 72.3 to 72.86Mbps, the changes occuring after modem resets or power cycles. Attainable rate (via the standard modem hack) has been 75272 to 76184kbps. Line rate has been 500 to 900 kbps below the attainable rate.
A few days ago we had a major power cut in the local area including here, lasting for several hours and afterwards, everything worked as normal. Just now I decided to check my BT profile and modem stats, just out of interest, as you do. The results are interesting - my profile has gone up to 75.73/20.00 and the modem stats are what I thought was impossible - line rate is much higher than the attainable rate! Stats are below.
Line is stable and needless to say I am delighted - I am now getting speedtest d/l results 3Mbps higher than ever before (74Mbps), but can anyone explain how line rate can be above attainable rate?

Who knows! I wouldn't say it would be impossible to hit pass your attainable rate, i would only take these as estimates as much as everything else.
It was like when i was on copper, thinking my line could only sync at 4MB, but constantly synced at around 6.5-7MB which was good for me! lol!

Decent line rate, throughput not consistent!
Hi folks,
On Wednesday I upgraded to the Broadband unlimited package, and with that got a Homehub 4.
Router setup went fine and broadband connected.
It has synced at a good rate but when conducting speed tests, the results range from a download of 15mb right down to the lowest Ive seen of 0.2mb. The results can be quite different from two tests done straight after eachother. There is no consistency and seems to be jumping all over the place.
The upload results remain around the 1mb mark.
My previous hub was a homehub 1 and although the last download sync I remember was 3.2mb, it was at least steady and I had no problems with it, besides the occasional reboot required.
Sync stats below:
Connection time:

Upload speed achieved during the test was - 0.99Mbps
Additional Information:
Upstream Rate IP profile on your line is - 0.83 Mbps
Looking around some of the other posts on the forum with similar issues, I suspect this could be an issue for a mod to sort out?
Thanks for readingSpeed check @ 21:15

Speed tests done today seem to have stabilised around the 14-15mb mark.
I noticed that my router reset this morning, with the noise increasing to 6db, not sure if this would help stabilise the throughput?

Data on HH2 Achieving Stable Line Rate & Switching...
In the thread "Re: Is HomeHub designed to be on all the time? No off switch?" the question was raised about properly switching off the router at the mains. I have collected data over the past few weeks which may give some guidance on this action, plus the changes as my line stabilises.
I pointed out in this thread that when entering the HH through the browser the Home Page opens by default. On this page there is a Connect/Disconnect button as the first listed item, whether this is also available on the HH type A or HH3 I don't know, mine id Type B. There are a few mentions of this button from a Forum search, but no clear reason for its function (not in the User Manual). I have found it in, for example, the threads, "Home Hub 2.0 wireless internet connection issues" in June 2010 & a clear mention by geoff93 in thread "Re: Sudden Drop In Speed (Again)" 1 Mar 2011; "Re: Broadband speed dropped from 10Mb to 250K overnight" on 24 Feb 2011.
In many threads the point is made that the HH should be left on continuously to keep the line stable as the DSLAM in the exchange checks the line at frequent intervals (about every 7-8 sec it seems on my line). I assume that using this Disconnect Button provides a logical warning to the exchange circuits that the line has deliberately been removed - it would be nice if the Forum Moderators could confirm if this function is in the design specification of the software and how the exchange system is expected to respond.
Following the four visits by OpenReach in Feb/Mar to sort my line arranged by the Forum Moderators (they were always most helpful when contacted) I left the HH on continuously from 21 Mar until 13 May with the following results which may be of interest

It seems that the line took 16 days (to 5 April) to stabilise at 14,336/1,078. The following 15 days after 13 May logically disconnecting/connecting seems not to disturb the line rate. However, I still get random disconnects/resets and also occasional disconnects when accessing the HH2.
The HH2 is running software 4.7.5.1.83.3.18, when I received it back in October it had ver ...83.3.5. The line distance to the Crowthorne exchange is ca 1000m.
Rodney FryIn the thread "Re: Is HomeHub designed to be on all the time? No off switch?" the question was raised about properly switching off the router at the mains. I have collected data over the past few weeks which may give some guidance on this action, plus the changes as my line stabilises.
I pointed out in this thread that when entering the HH through the browser the Home Page opens by default. On this page there is a Connect/Disconnect button as the first listed item, whether this is also available on the HH type A or HH3 I don't know, mine id Type B. There are a few mentions of this button from a Forum search, but no clear reason for its function (not in the User Manual). I have found it in, for example, the threads, "Home Hub 2.0 wireless internet connection issues" in June 2010 & a clear mention by geoff93 in thread "Re: Sudden Drop In Speed (Again)" 1 Mar 2011; "Re: Broadband speed dropped from 10Mb to 250K overnight" on 24 Feb 2011.
In many threads the point is made that the HH should be left on continuously to keep the line stable as the DSLAM in the exchange checks the line at frequent intervals (about every 7-8 sec it seems on my line). I assume that using this Disconnect Button provides a logical warning to the exchange circuits that the line has deliberately been removed - it would be nice if the Forum Moderators could confirm if this function is in the design specification of the software and how the exchange system is expected to respond.
Following the four visits by OpenReach in Feb/Mar to sort my line arranged by the Forum Moderators (they were always most helpful when contacted) I left the HH on continuously from 21 Mar until 13 May with the following results which may be of interest

within this whole period I still had random disconnects/resets.
From 13 May I started to now run the HH2 with the power switched off at night (usually), until I decide to switch on the PC the next day, or later.

Cisco 878 "priv" command password recovery in Rommon mode
Hi,
There was " Cookie information corrupt" error on cisco 878 and I enter cookie information with cookie command. The priv command password is "0000" when all cookies zero, but I inserted wrong cookies . I want to edit cookie information. The priv command password changed and I can't edit cookie informations.
How can I recovery priv command password in rommon ?
Thanks for help,Hi friends,
I solved problem. You must add the first five numbers in 16-bit hex in cookies :
Sample :
00
01
+
00
30
+
85
d7
+
e0
60
+
0a
ff
= 17167
The password is only four characters, so remove the most significant bit and the password is 7167. -
Very slow download speed though modem line rate no...
Hi
I recently noticed (today, 31st December) that our download speed had dropped very low, to approx 0.5Mbps. The upload speed is normal, approx 1Mbps. The modem line rate is however normal (8Mbps dowm, 1Mbps up). I have checked the download speed using http://speedtest.btwholesale.com/. I am at postcode SK237FN and have had consistently reliable download speeds for several years, 5-7Mbps.
Please help!
I already tried rebooting my router but this has not improved matters.
Thanks...

It looks like my FTTC 40/10 download speed has dropped its was downloading at 28Mbps for a long time and now getting 24Mbps the attainable rate is steady at 33600 - 34800 but line rate has gone down from 29400 to 26093, the only thing I did was to turn off the HH3 overnight and line rate has stuck on 26093 it now over 2 days will my speed come back ?
Solved!
Go to Solution.Did you just leave all your equipment alone for 2 weeks for it to increase or did you do a turn on and off job after 2 weeks?.

Hello
What is the OID of the noise margin for the cisco 878?
I have found in the MIB of router the parameter hdsl2ShdslEndpointCurrSnrMgn but the snmpwalk query does not match the show controller dsl 0!
Any ideas?

Receiver Gain: 14.420 dB
SNR Sampling: 34.2500 dB

Cisco SPA - Monitoring Line Status
Hi,
I have a Cisco SPA112, though this would apply to the Cisco SPA122 as well.
It has the latest 1.3.2 firmware on it.
I want to monitor the status of Line 1. If I changes to being Unregistered, I want to know.
How are people doing this at the moment?
I can SNMP walk the device, but I can't see an obvious OID there that gives me the status.
How are people monitoring the status of their ATA's?
Thanks!
TimIs there any way to get the Line 1 status from the web page without having to login?
Or is there a way to login programatically using wget etc? -
I need to take an encoder in TTL format into trigger line 0 and redirect it to output control line 0 so that the board drives it in LVDS format. This will become the External Sync line for the Dalsa CL-P1-2048 line scan camera. I assume this is done in the icd file, but the documentation on this subject and the 1422 itself is extremely poor.
Brian,
I do not believe you are going to do exactly what you are looking for since there is no way to write to the control lines programatically or from the camera file. If you are looking to use this signal to trigger each line, you may want to take a look at this example:
http://zone.ni.com/devzone/explprog.nsf/6c163603265406328625682a006ed37d/f2799dc12a94be2586256a79006985ce?OpenDocument
It uses motion and routes the encoder signal across for the line trigger. You can modify this so the input trigger is from your trigger line. I hope this information helps.
