Cisco Router 877W ADSL Configuration?
Nov 18, 2012
While i was looking around in my stuff in the office i have found a Cisco 877W ADSL router .. so i have decided to use it instead of the one i am using now which is provided by the ISP that's made by Huawei.Anyway i have a good knowledge about basic cisco router configuration but i had never configured ADSL Cisco router, so i looked around on Cisco website, and i was lucky to get this two linksCisco DSL Router Configuration and Troubleshooting Guide - Step-by-Step Configuration of PPPoA with a Dynamic IP Address - Cisco Systems[CODE]

Is the ADSL line interface on Cisco 877W not initialising a known issue? This interface on my router has been in this state for more than one month, with the rest of the router seemingly operational. The interface was connected directly to my ADSL broadband and worked well for two years. But then, about a month ago, the interface went down. I saw the exact moment this happened recorded as a syslog message. The only information was that the interface status had changed to down.
Initially I thought this was a matter of reload the router and all will be well. Did not happen. Then I thought my broadband connection was to blame. However, this option was quickly ruled out. So I went on to exhaust all troubleshooting options, including reflashing the router with the saved image and totally changing the configuration. Still no change. I have had to go back to my old BT home hub for internet access. In terms of speed this actually works a lot better than the Cisco router. But I would still rather have the router connected to my broadband line. What can I do to bring the ADSL interface back to life?

I have an 877W router that I would like to have a 2nd pre-configured backup for. I was thinking of getting another 870 series (probably an 877) router, as the more expensive wireless option is not actually required. Am I right to assume that I could simply copy the contents of my current config.txt file onto the second router?

Looking to setup a backup router for our disaster recovery plan. We currently have a Cisco 877W that was setup by our ISP. I can log into the device with Telnet and a console cable, but I am not good using IOS commands, so I would like to use CCA. Unfortunatley, I cannot access the router using the software. I assume something is disabled in the config. Like HTTP or something.

NTP server When I setup NTP server to take time from [URL] everything is working fine but as soon as I reset my router during boot I can see that router is first trying to get time before it's even connected to ATM and when it can't get time from NTP server it's removing NTP line from configuration (ntp server uk.pool.ntp.org source Dialer0 ). How I setup to wait with sync and do it once ATM connection is up and established? Or How to get IOS to leave this line and sync with NTP every 10 min)?

I need to configure ADSL on my 837 Router with simple configuration. The WAN IP address is dynamic from my ISP. I checked many websites and found different configurations everywhere. I don't know which is best suited for me. I used SDM and configured ADSL. When i checked the configuration from console i found that there is atm0.2 and dialer 2 configured with my settings. I cannot understand what is the purpose of atm0.2 and dialer 2 when atm0 and dialer0 are there. Is there a doc on ADSL config on 837?

I am configuring a 1841 router for use in small out office. I will use the s0/0/0 for main WAN T1 connection. I then wanted to use the ATM0/1/0 WIC-1-ADSL card as a failover. I am using weighted static routes for failover. Fe0/0 is LAN interface. When I go into SDM and look at the ATM interface it says this configuration is unsupported?
1. Can't I just get a DSL modem and connect it to fe0/1 and not use ATM WIC and use below for failover?
2. If I have to use ATM WIC what needs to be configured for it to work with Att aDSL?

I have a Cisco 1841 router with an HWIC-ADSL module installed. My ADSL connection is PPPoA with a dialer interface and I have been provided 6 ip's from my provider to use on this service. Previously I have connected Fa0/0 on the 1841 straight onto my network and used NAT and ACL's on the 1841, I would now like to change this and have Fa0/0 connected to a Palo Alto firewall and use the Palo Alto to provide NAT, Firewall & site to site VPN functions. What config would I require on the 1841 to allow me to use one of my ISP IP addresses on the Palo Alto to allow it to be a VPN endpoint? Do I need to configure the 1841 in bridge mode?

I'm replacing an 877W router with an C887VA-W-A-K9.The new router uses the service module for managing the AP independently - So I know I can't simply paste the config accross from the old one.
The current router is connected to an ISP with a VPN back to the head office router. DHCP is supplied from the router and clients connect to that via wireless.
I know I can type most of the commands in - but what is best practice going from an all-in-one to having a separate AP? What order should thing be entered?

Probably this is a trivial question but I have not found any response to it. What I would like is to set my cisco 877W rotuer up in order to act as a DNS server which forwards DNS queries following these simple rules:
1.- If the name is within my local domain *.ib forward them to my local DNS 172.21.238.229 and .230, and
2.- Else forward them to the chosen public domains (i.e. 8.8.8.8 and 8.8.4.4).

Cisco 877W. I configured it for PPPoE. But once I plug in the ADSL line, the dialer interface will get IP Address. But after like 2 minutes the PPP link will go off and I will get this log message: "Interface Vi1 unbound from profile Di1".

I have a Cisco 877W in place with an ADSL connection, which is working fine. However I cannot get it to hand out a DHCP address. If I associate with the AP over wireless then set a static IP I have full connectivity, similarly if I connect over Eth0 and set a static IP I have full connectivity. So it does just seem to be DHCP. Below shows my config... Any thoughts on the issue? Is it access-list related?I have checked with Wireshark and I see the DHCP request being sent out, but I don't see a DHCP offer being returned

I am running an 877W in the home that for the most part works fine, however after being connected for a variable amount of time I partially loose my DSL connection. Line sync stays up, but the traffic is lost.
A shut/no sut of the atm or dialer interfaces does not resolve the issue, only a reload or power down/up will fix the prob short term till it happens again.
Am currently running advipservicesk9-mz.151-3.T1, but have also rolled back to advipservicesk9-mz.124-24.T5 which has the same issue. Have tried a 857W with the same results. So ruling out IOS and hardware, its pointing to a config issue. It has also only been an issue since changing from ADSL1 to ADSL2+.
interface ATM0
no ip address
no shutdown
no atm ilmi-keepalive
exit

I've tries some changes mentioned here and from other sites, but no success yet...

I have a working easyvpn setup. We need to change the HQ ip address (current it is i.e 85.146.110.101). This is ACL is applied to Fastethenet conecting to ISP:
interface FastEthernet4
description $FW_OUTSIDE$$ETH-WAN$
ip address dhcp
ip access-group 101 in
ip inspect SDM_LOW out
ip nat outside
ip virtual-reassembly
duplex auto
speed auto
crypto ipsec client ezvpn Acom
As soon as I apply again the ACL to interface Fastethernet 4, access to internet is lost. If I put original ACL 101 (with ip address 85.146.110.101) it works fine.
So I am wodering what wrong with may ACL? Should I make the change via SDM not CLI (to be honest I did not know/use SDM before today)?

I've an 877W with four V LANS, All bridged (group) onto a BVI which is bonded to ATM etc for ADSL:
c870-advipservicesk9-mz.124-15.T5.bin"
1 is the backbone, and for the switch, and has DHCP running and working with no problems - x.y.1.z . Multicast is enabled so that various multimedia bits of kit can find each other.
2 is the "primary" WiFi, which has android devices as they cannot handle SSID not being broadcast or devices that can only do wep.(WiFi radio) it has DHCP, x.y.2.z which works fine. Multicast is enabled so that various multimedia bits of kit can find each other.
3 is a secondary WiFi for the kids, "hidden" ssid. They are fire walled so that bugs can't infect any other windows PC DHCP x.y.3.z.
4 Is a secondary WiFi for our laptops, "hidden" ssid .
For some reason, DHCP is not working on 4. it was working until the good lady of the house quizzed why her net was not working... I've concentrated on vlan4, as there are no "local" access-lists definitions to stop anything. I've enabled debug ip dhcp server, and can see requests serviced on Vlan2, but not on 4, I've enabled/re enabled encryption/ shields on Vlan4, but still can't see dhcp requests arriving and do not see them being stopped somewhere. I can see that the station authenticates OK, but if I connect the same laptop to v lan 02, requests pour in and are answered, proving it's maybe not a Microsoft problem.
Let me just say, I'm more or less self taught with the the net, no real mentoring, so 'think' I have the general idea of the different layers, access-lists etc. so this config is probably not ideal, but it works.
version 12.4
no service pad
