Cisco WAN :: PPPoE Dialer In VRF Disables IP Address Negotiation 887VA?
Feb 27, 2011
We are trying to take ADSL interface into another VRF i.e (ip vrf forwarding VRF2 under dialer interface), the ip address negotiated command disappears, and although the dialer interface becomes up-up state, the adsl interface does not get an IP address dynamically.
Tried:
1) to reenter ip address negotiated again after changing the vrf of the interface, still the dialer interface shows "no ip address" under configuration
2) ppp ipcp accept-address again does not work.
the IOS version:c880data-universalk9-mz.151-2.T1.bin
I have found this workable cisco 1841 config on the NET. From this link: [URL]
But it is doing source NAT from FA0/1 to Fa0/0. If we need to bridge, is it need to use “ip unnumbered”?
See my config below” 1841 config for Unifi, with ip unnumbered“, can work?
1841 config for Unifi, with NAT !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ! ! ! Works perfectly on Cisco 1841, IOS v12.4(24)T !
I'm trying to configure an 887VA for a pppoe ADSL2+ connection with no luck.I know the ISP requires pppoe (LLC), and the pvc is 8/35. The CD light is on, and the line is up, but the 887 just won't connect
I've struggled now for a couple of days to setup a PPPoe connection on our cisco 887va box. I can setup straight away on a draytek box so i know the connection is good.I can't get the line protocol to come up? It's connected via ethernet port 0 to an external modem. One thing i can't figure out is if ethernet 0 and fast ethernet 0 is the same physical port?I've attached the running-config below.
I've got problem trying to connect the CISCO-887VDSL/ADSL OVER POTS ROUTER to internet. Only got the LAN part working.I'm trying to setup PPPoE with dynamic IP Followed CISCO's documentations but the commands used were not recognized by the router.
here's my config.

difference of CISCO887VA-K9 and CISCO887VA-SEC-K9.I thought it because of the Advanced Security and Advanced IP Licenses, but it isn't, I've got the -SEC- Version now just with the Advanced Security license. So I asking myself why I bought the more expensive CISCO887VA-SEC-K9 if I have to buy the additional Advanced IP Services licenses extra..
I have been working on this for hours and getting frustrated! This router has been set up for over a year with no trouble, but recently had trouble connecting with my wireless devices and was kicking my wired (ethernet) laptop off when it is usually on all the time.
Now, my wired connection works through the router, the wireless devices all connect to the network but do not have access to theinternet. From the router's setup page, when I enter my PPPoE information and go to status and connect, it tries to connect a few times then gives me the error message 'cannot get IP address from PPPoE server"
I have tried updating firmware, resetting, restarting, recycling power, chat support with ISP and chat support with Linksys. Have verified my username and key and those are correct otherwise I'd have no internet access at all. I do have wired access but not wireless. The wired connection does go through the router.
Bridging - my modem is a bridging modem only, so it shouldn't be that.
I've a D-Link DFE-520TX PCI Fast Ethernet card, which is/was excellent until this first problem. 2 nights ago there was some good lightning/thunders activity, resulting in burning of ISP network switches. This morning they replaced the switches and brought up the network, but here's the problem:1) Under the default card setting with Auto-negotiation, PC looks for DCHP Server address resolution and ends up with YELLOW triangle in the system tray.2) Whereas, when I CHANGE the card setting to 10Base in FullDuplex, then PC gets connected to the ISP network.ISP support said that either the card could be damaged due to lightning strike or it could be due to damaged cable running from port box to the PC (RJ-45). I'm wondering, could lightning strike damage a Network card in such a partial manner (just one feature, i.e., Auto-negotiation)? But that person warned, there will be deterioration in ISP speeds when I use 10Base in Full Duplex (for now) compared to Auto-negotiation speeds. Speeds really came down badly, that's understood.
confirm if "negotiation auto" is supported gigabit port for C3925E router.

I have a question about speed negotiation process between interfaces. I have 3650X Sw and 2960S-48port. All ports of two are GigabitEthernet, however the link between them is only 100Mb/s, Full duplex. I try to set the speed 1000 Mb/s manually in the interface then the interface never up. Its status is down/down. I must set back to speed auto. I show interface Gigabit0/24 in Sw 3650-X and figure out that there are many output drop (over 600000). I clear counter then after two days the output drop is over 70000. This link is trunk link between two switches, all ports of access SW are Gigabit and connect to PC. First, I thinks the 3650X is throttled somewhere in output direction of trunk link. But there is another trunk link (Gi0/23) to another 2960S-48port and no output drop number in this interface. This Giga 0/23 speed is 1000 Mb/s (auto speed, auto duplex)
Does any outside things impact the speed negotiation process between 2 interfaces? And output drop number may caused by abnormal speed between two Gigabit interface?
We are facing to an annoying issue. We have a 6509 running in Catos 8.3(4) with WS-X6548-GE-TX, WS-X6348-RJ-45 and WS-X6148-RJ-45. When we configure the mode in auto negotiation, it comes up in half duplex. We need to configure the speed mode at 100Mbit/Full to make it work. But if the chassis or port restarts (not the server), the link becomes half duplex. This happens only on module in Gigabyte like WS-X6548-GE-TX.
Cable have been replaced but does not work. It is not happened on another chassis running on IOS 12.2(18)SXF17b with WS-X6548-GE-TX.
Nexus 5500 support auto negotiation on 1gig sfp port? There is an end device that only support auto negotiation and cannot be manually set speed/duplex.
We have a customer running a RV 120W, and if the internet connection is disconnected it disables NAT, and you have to log on to the setup and enable it again. This is very annoying if the net connection goes down as you have to manually fix, why it does this and how to make it enable NAt by default?
My computers Network adapter (integrated with the motherboard 'no fancy stuff') disables, though only when I'm putting a bit of pressure on the system. i.e. when playing skyrim etc.I have resolved the issue temporarily by connecting straight to the computer instead of the inbetween switch, but at the cost of only being able to connect this computer at home. The strange thing in my opinion however is that when we have 3-4 computers all connected through the switch, only this one has this error that keeps occuring.I've checked into the power savings settings, as I'm conviced it's some kind of setting on my machine, and set them to max performance as well as disabling windows from beeing able to disable the NIC to save power.
1. Internet works ok, everything is fine, but then it stops working for no reason.
2. I open Network and Sharing Center, and do diagnostics. They come up with result: "the default gateway is not available". Nothing works. But Local Area Connection and Network Controller are both enabled.
3. I have to restart computer for the internet to work again. However, it doesn't restart: it hangs forever in "shutting down" screen, and nothing happens. Probably because computer is still trying to connect to the internet (?)
4. After forced restart, internet doesn't work, but if I run diagnostics again, they come up with result: "The Local Area Connection adapter is disabled", and fixes it automatically. Internet works then.
Whichever download manager I use, when ever it starts downloading for a bit it somehow manages to disable the wifi on my router. This makes it impossible for me to leave things going over night which is annoying. It happens with IDM and Jdownloader.
I've been trying to use my laptop (Lenovo IdeaPad Y580) as a wireless adapter for my Xbox 360 by bridging the LAN/Wireless networks and connecting the Xbox to the laptop via Ethernet. The wireless works fine normally, but when I plug the Ethernet cable into the computer, the laptop automatically disables WiFi and changes to a LAN connection. It doesn't give any options whatsoever to reconnect to wireless, just forces me to use the Ethernet connection. As soon as the cable is removed the wireless connection returns, but for what I'm trying to do to work, I need both LAN and wireless to be working simultaneously, and the wireless providing the Internet connection. I've also tried connecting the laptop to a router via Ethernet and received the same result, so I'm pretty sure it's something on the laptop that's causing it. Is there a way to change this so the laptop can use the wireless connection while plugged into another device via Ethernet?

I have an RVS4000 setup with a VLAN to a wireless "guest" network, guest network is 192.168.1.x, internal network is 10.0.0.x both have Internet access, and cannot see each other, exactly what I wanted. The only problem is that either from the internal network or the guest network I can no longer access the Remote Web Workplace - [URL] or Outlook Web Access [URL] fails with page not found. Internally I can access via \server emote and \serverexchange but of course this does not work for the guest network. We have Small Business Server 2003. External access if fine.
We have recently deployed several Ciso 887VAW (IOS 15.1(4)M4) to customer premises and I have come to realise counters show extremely high (not at all accurate) output rate and packets on all of them. [code]
I have an 837 ADSL router that the customer is upgrading from a 3 meg circuit to a 10 meg circuit.
The previous vendor used PPOE for connection and we used a dialer 1 interface to make the connection with a user name and password.
The new connection is a straight WAN DHCP no username or password needed.
I realize I can change the dialer interface from negotiate to DHCP but do I still need it ?
Can I replace the dialer 1 interface with IRB ? Should i just keep the Dialer 1 interface since the device is currently set that way and just remove the PPP negotiation from dialer 1 ?
I have the exact same problem: network adapter disconnects itself and I am unable to disable and enable it again, because it is unresponsive under the device manager and the network and sharing center. The only solution is to reboot the computer, where I can then have access to the network adapter and can reset it.This is since I upgraded windows vista to windows 7 4 days ago. I have upgraded all the driversI have uninstalled the network adapter driver and rebooted, and reinstalled the latest update with no difference.Running the computer in safe mode with networking has not yielded a crash so far, but have not tested this enough.I have tried disabling IPV6 as some people have said this could be reason, but it still crashes.It is somewhat different from what many people mention as I cannot reset the connection without rebooting (which I could live with). I do not use torrents or any site like that.
I just got a new HP EliteBook 8560w(Win7) but when I connect an Ethernet cable, the wireless becomes disabled. With my older Dell machines(WinXP) I could use both [DHCP for wireless and 192.168.1.x on the copper/Ethernet].Is there a way to prevent the wireless from being disabled?
I have a webserver running and have port80 open to recieve requests. Every once in awhile the router randomly disables this port from being forwarded. It is only this port none of the other ports I have open are disabled. I tried switching the server to another port but had the same problem.I have assume its some kind of security feature, since the server gets many requrests that it shuts down the port?
I am experiencing the same problem described in this post {URL}. I have seen this happen on different networks, with different equipment attached. It happens on both 2960 and 3750 switches. Basically the connection drops, and we see in the web interface "Port is Disabled". This appears to happen every 10 minutes.
On the CLI, the status shows as connected.
Port Name Status V lan Duplex Speed Type Fa0/38 connected 1 a-full a-100 10/100BaseTX
I have ran cable diagnostics while the drop out is occurring.
Interface Speed Local pair Pair length Remote pair Pair status --------- ----- ---------- ----------------- ----------- ------------------- Fa0/38 100M Pair A 28 +/- 15 meters Pair B Normal [code]...
During the outage, I see the duplex fluctuate between full and half. The outage occurs for approx 90 seconds. If I fix the duplex and speed at both ends, the outage reduces to around 30 seconds. If I apply spanning-tree port fast the outage reduces further to around 10 seconds. Before I change any configuration on the port, the logs show the interface going down
Aug 16 13:06:51.875: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/38, changed state to down Aug 16 13:06:52.874: %LINK-3-UPDOWN: Interface FastEthernet0/38, changed state to down [code]...
However, once I apply the configuration nothing is logged. However we can still see the connection is disappearing for around 10 seconds. I suspect the issue wasn't resolved for the person reporting the problem in the link above, but because the outage is minimized, and not being logged it is going unnoticed.
I have applied a crypto map (fo ipsec vpn) on the dialer interface (for PPoE connection) in Cisco 2800; every time when the router restarts the crypto map is removed from the dialer interface even though i save the configuration every tim when i apply the map on the interface. Is there any way that the crypto map remains there on the dialer interface after the restart of router.
How to make a Cisco 881 router finally work. I have the following configuration:

As much as I understand, the VPN tunnel is active.I can access the Internet, but I cannot access anything through the VPN tunnel.
having some issues with a configuration using a Dialer interface. The interface comes up and the VPN tunnel comes up, but cannot access any network resources or the Internet.
The things that concern me most are my access lists as I have the static IP address that we are assigned via PPPOE - the IP never changes, but not sure if I can define it in the ACL or if I should be using an ANY tag.
Note: I've changed some IPs and username for security reasons.
I have a Lenovo G550 laptop with Windoows 7. For the past year it has been periodically (every 5-10 minutes) losing connection with a wireless network. It doesnt matter what network I use , it does the same thing. When the connection is lost it will also cause any other wifi devices (computers, phones) to lose there connection and have to reconnect. I have tried just about anything and everything including using an external usb wifi.
I am trying to enable the workgroup bridge mode on the 5ghz 802.11N radio of a Aironet 1262N, but when I select the workgroup bridge mode from the GUI the radio becomes disabled. If I select the Access Point role from the GUI then the radio instantly becomes enabled. The same thing happens if I attempt the same procedure with the 2.4ghz radio as well. I can get the radios from both bands enabled if I select the Access Point role. I made sure to check that both radios were not set to workgroup bridge as well. I am running 12.4(25d)JA1 code on the AP. This is my first time working with this type of AP.
I am trying to copy a setup from a Nortel IAX100 where the carrier provides two ATM PVC's over ADSL - one for voice (VoIP) and one for data (IP). Relevant lines from the backup of the IAX's configuration include the following for the PPP authentication over the voice circuit:
The null username and password for the PPP connection have me a bit stumped. Does the PPP connection not use any authenetication at all? (Is that possible/likely? How could I deubg it?) Or does does the IAX100 supply a chap/pap response with null credentails? (If so, how would I duplicate that using an instruction to a dialer interface?I am configuring an 877 with 12.4T and advanced IP services.
