Cisco Infrastructure :: ADSL Disconnects On 800 Series Routers

Mar 21, 2012

We have deployed a number of 800 series routers for some of our clients and have found that in many cases they seem to disconnect at an excessive rate. When I connected to the console of one the other day I could see that the virtual-interface for the ADSL connection was down, but not the ATM or DSL interface. If I disconnected the cable and reconnected the virtual-circuit came back up momentarily before disconnecting within a minute.
 
If I switched off the router for a few minutes and powered it back on it would usually remain up for a few hours. I reconfigured the router again using exactly the same config and it seemed to stay up for quite long periods for 4 or 5 days before reverting to type. [code]

Cisco Infrastructure :: Connecting To Console Of 2600 Series Routers

Aug 30, 2012

I bought some hardware and created my own lab to prepare for the CCNA.  I only have one machine with a serial port and whenever I try to connect to a router (I've tried multiple purchased from different sources) nothing happens on the screen.  If I wait for a couple of seconds and hit enter I get the response shown on the screen in the screenshot I have inserted.  If this image is too small I have also attached. looks like it has already asked me this but I am unable to see it.  Shouldn't I see some information when I attempt to connect, some acknowledgement that I have connected?  I have tried using both hyperterminal anbd PuTTy.

Cisco Infrastructure :: Will WIC SHDSL-V3 Able To Support ADSL Line

Apr 10, 2013

I do have a question, is WIC-1SHDSL-V3 able to support ADSL line?
 
We have WIC-1SHDSL-V3 module used for SDSL line, due to few site need to bring up with ADSL line with 1841 model, but HWIC-1ADSL module already EOS. The replacement model EHWIC-VA-DSL-A is not compatible to 1841. My architect suggest Symmetric Module like WIC-1SHDSL-V3 could be able to tweak the config to support Asymmetric purpose. I did google but do not found such related topic. Can any expert on this area to advice me?

Cisco Switching/Routing :: 2800 Series - Dual ADSL Links?

Jan 31, 2012

In a site we currently have 1 BT provided ADSL link which is currently terminated using their device which I believe is some kind of 2wire device, which is extremely slow due to distance from the Exchange (4Mbps)...We have a growing number of users here and want to install a second ADSL line from BT to give them increased performance.
 
We have a Cisco 2800 sat not doing much so I was wondering if I could use this to load balance the link? I know BT do not support MPPP so therefore the maximum any user can get will be the speed of a single link (4Mbps)...But basically how can this be done..
 
Can I leave the two BT routers in place and place the Cisco 2800 behind them, or do I need to purchase two ADSL modules for the 2800 and terminate the connection there?Also once done, what do I need to do regarding actually setting up the load balancing? I have seen this:
 
[URL]
 
But am unsure as to how relevant it is? I am not sure I understand what the ACL's are being used for? I just want all users on the LAN to load balance out...
 
Also I am unsure of this statement:You potentially need to add policy-based routing for specific traffic to ensure that it always uses one ISP connection. Examples of traffic that require this behavior include IPSec VPN clients, VoIP handsets, and any other traffic that use only one of the ISP-connection options to prefer the same IP address, higher speed, or lower latency on the connection.I do not understand why a established session such as a VPN client, would ever traverse the second ISP connection anyway?

Cisco Routers :: How Does Quality And Longevity Of SRP500 Series Compare To RV Series

May 27, 2012

My Draytek 2710 just dies after 2 years so I was looking for something a little more reliable and noticed the spec of the SRP527W-U.I take it with only one antenna and reading a couple of past discussions, the wireless will only manage n-lite as some people call it i.e. 150Mbps, and not the full 300? Oh, and are the ports still only 100M and not Gig?I know the 547 would tick both these boxes but we are talking twice the price.  How does the quality and logevity of the SRP500 series compare to the RV series (which would need an adsl modem) or the Linksys boxes?

Cisco Infrastructure :: NM-1Fe Fastethernet Module Not Compatible With 2 Series Routers600

Oct 13, 2012

I understand that the NM-1FE Fastethernet modules are not compatible with Cisco 2600 series routers, just the Ethernet 1-E module.  With that being said, are there ANY modules supported by the 2600, 2621 or 2621XM series routers that have fastethernet port(s) outside of the pricey NM-16ESW module?  I don't need a 16 port module!

Cisco Infrastructure :: Network 3501 Series Could Not Find Information

Oct 2, 2011

I am new in networking. All my knowledge is based on books and no real life experience. At my job I am required to set up the network and configure all apparatus I never worked before with.
 
We have regular cable internet in the office. Modem is connected to Apple router (time capsule). No trouble. Now we are getting fibre optic in the office. Mngmnt has abought the following Cisco stuff:
 
Cisco Wireless Controller 2504
Cisco 3501 AP 802.11g/n Ctrlr based AP
Cisco  ASA 5510 Firewall appliance
Cisco Power Injector AP3500 Series
 
According to my understding, the fibre optic point will be connected to ASA which will be further connected to wireless controller and then access point.
 
I cant find the requird info. The guides available at cisco are for when you use CLI and as a beginner I prefer to use GUI. While trying to config ASA, there are many questions I can't find the answers.

Cisco Infrastructure :: GSR 12000 Series / Can MPLS Aware Netflow Version 9 Be Enabled On Catalyst Switches

Jun 9, 2003

I'm working for KOREA TELECOM, and currently providing MPLS VPN.We're planning to provide our customer with traffic report using NetFlow..
 
I read some documents which reads Netflow ver.9 can be enabled on Cisco GSR 12000 Series, but no mention about  catalyst switches. Netflow ver 9 can be activated on catalyst 6500 series.. because the point where switch is located already have mpls encapsulated packet ( mpls vpn packet).

Cisco Routers :: SRP 527w - ADSL Disconnections

May 12, 2011

at our office we've recently upgrade from a old consumer-grade linksys wag200g modem/router/ap to the Cisco SRP527w. The Cisco is suffering from very frequent ADSL disconnections. These disconnections happens when there is some traffic to the internet and they seem to don't affect the LAN routing: on the weekends there are no disconnections at all while during the working hours there may be disconnections every FEW MINUTES making this router unusable. Often these disconnections force us to do a full reboot of the router.
 
Firmare version is  SRP520W-1.1.19, the latest. ADSL line is a 6Mbps/640kbps. Noise margin is about 11dB for downstream and 20dB for upstream.
No voice line is used and therefore they are both disabled. 2 wireless network are active. The old linksys was (and is) working correctly, no adsl disconnections at all. Never.

Broadband :: Connect 2 ADSL Routers On 1 BT Line?

Feb 19, 2011

Our church has 1 phone line, we run BTBusiness Broadband at one of the building where we have a couple of charities based. We have the phone line connected to an extension at the other end (where the Church is) >80m away. Any way of running a second concurrent router on the extension so I can set up an office with a VOIP number, pC's printers etc there too? We use Devolo ethernet over mains and wireless for the main building, but the church itself is on a completely seperate mains power supply so I can't use that. I could run 100m Cat 5 and locate a switch on that, but any way of achieving something similar over the phone cable which is already in place.

Cisco Switching/Routing :: Load Balance Between 3 877 ADSL Routers

Apr 25, 2012

I have 3 877 ADSL routers for internet connectivity.  I recently installed a FW behind them and would like to use the Ciscos as load balance in order to get better utilization from my 3 internet links.
 
1) the 3 routers are on DHCP from the ISP on the WAN side.

2) the 3 ciscos are on the same class C subnet on the LAN side: 10.201.1.252, 10.201.1.253 and 10.201.1.254

Cisco Routers :: Total Failure To Get SR520-ADSL-K9 To Connect To ISP

Dec 15, 2011

We've (an independent school) just bought an SR520 with a view to replacing one of our Draytek 2820s. We need to set up some site-to-site VPN with NAT and the Drayteks won't do it.
 
I've been trying to configure the SR520 in just the most basic fashion using CCA (3.1) and the CLI but with no success. I can't get a PPP connection with our ISP.
 
I've tried following the instructions in the software config pdf and also tried replicating the various 'running configs' reported in other posts in this forum to allow connection to a UK ISP, with no success. I don't know how many times I've reset the poor thing to factory defaults.
 
I have to say that I'm dismayed at how flaky the CCA appears to be. Many of the things I've tried with it simply don't work and often end up in it hanging. Close to useless in my view.
 
So instead I've tried to use the CLI which seems a lot more solid but is somewhat impenetrable and there's precious little by way of supporting explanation.

Cisco Routers :: WRV210 - Quickvpn Disconnects - Remote Gateway Not Responding

We have 2 remote locations that are connecting to a server at our home location.  Each remote computer uses quickvpn utility to establish a vpn with the home location.  Our problem is that sometimes the vpn disconnects while we are working in remote desktop on server 2008.  Luckily our sessions in remote desktop stay put but we lose the vpn connection.  Most of the time we get a message that the remote gateway is not responding.  Our dsl internet connection seems to work and we have previously had no trouble with connecting to the home location.  We have 3 computers that connect simultaneously to the server at each remote location and sometimes one computer will stay connected while others disconnect.
