Cisco WAN :: Set Up WAN Interface On Fast Ethernet Interface Of 877 Adsl Router

Apr 9, 2011

Is it possible to set up a WAN interface on a FastEthernet interface of a Cisco 877 Adsl Router ?Due to my ISP, i've to use an external VDSL modem and must connect it to my cisco 877 router (and leave it's adsl interface unused).But i don't know how to set up a wan port, other than the adsl interface itself (dialer0), on my cisco.

Cisco WAN :: 7200VXR - NPE-G2 Fast-Ethernet Management Interface?

Apr 30, 2012

Is there a keyword that we use under the interface to specify that it is purely management?
 
We need to assure that the subnet and any node on that subnet is not shared with the default routing table.
 
how do we set the gateway for the management interface if the node we are sourcing the ssh session from is on a different private subnet?

Cisco WAN :: Fast Ethernet Interface Being Take Down With Burst Of Traffic 2800

Jan 12, 2011

It is a single router with dual ISPs. It is a 2800 and there is failover configured. I have implemented object tracking and the feature works great except that lately, whenever there is a lot of traffic coming perhaps from the internal users, we start getting intermittent outages.
 
I have gone deep into looking into this problem and have determined that our ISP#1 does not have any problems. What I think is happening is that whenever the router receives a lot of packets (30-40 users on the internal network) destined to the outside, the router CPU maybe gets too busy and the router then believes that the objects are no longer reachable and it triggers a failover which causes the router to re-direct traffic to the ISP#2. Then, because these are just quick burst of traffic, in the next 30 to 45 seconds after the router re-directed the traffic to ISP#2, the router object tracking engine detects that the objects are now again reachable and this then causes the router to re-direct all traffic back to ISP#1.
 
This cycle then continues all day on how to prevent this.

Is there a way to perhaps tell the router to completely shut down the interface facing ISP#1 whenever there is a hicup and to keep it shutdown for at least 8 hours? This way I can prevent the router from going crazy.
 
Or is there a way to perhaps prevent this at the internal (LAN)  interface? Are there some metrics like QoS that I can implement on the internal Fast Ethernet Interface to prevent the burst of traffic from eating up the CPU?

Cisco Infrastructure :: 3660 - Interface Resets Over Fast Ethernet

Mar 20, 2005

I am troubleshooting interface resets on a 3660 connected to a 3550 over Fast Ethernet. I have hard coded both sides for full duplex and 100Mbit. The 3660 is incrementing interface resetes about 4-6 times a day and the 3550 is clean. I have noticed this in other similar configurations as well.

Cisco Switching/Routing :: ADSL On Fast Ethernet In 1801?

Apr 24, 2012

I have cisco 1801W . Earlier I am using ADSL dynamic IP address  on RJ 11  through the ADSL Port but now the ISP change the connection to RJ45.
 
I am trying to configure it but unable to do this. ADSL line is okay because When I am connecting through the ISP router it is working fine. I have connected the ADSL RJ45 cable in the router fast ethernet 0.But I wanted to use Cisco 1801 Router so that I can use the ADSL as primary and ISDN as the backup.
 
Below is my configuration, eiteher this is possible to configure ADSL through RJ45 in 1801 and what configuration require for this.  
 
Router#show ip int brief
Interface                  IP-Address      OK? Method Status                Protocol
FastEthernet0              unassigned      YES DHCP   up                    up
BRI0                       unassigned      YES unset  administratively down down

Cisco WAN :: 1841 ADSL Interface Dropping Connection

Jul 2, 2012

We have an ADSL2+ line from a WIC in a 1841, everything has been fine for the last few years and then the last few months the connection going down. When checking the interfaces the ATM0/0/0 is up up and the same for the dialer interface we are using, they are both up/up, but this still needs a reload of the router to be functional again, shutting the interfaces does not bring the connection back up.
 
I am not an expert on ADSL lines, I have never really had a problem with anything previously. The router was running Netflow to a network monitor wondering if this or logging was causing an issue with entries in the buffer??
 
Here is an output of show dsl int, would change the firmware, it has been fine all this time before though we are running IOS 12.4(24)T1 advseck9-m, as far as I can seen from our ISP the config for ADSL is all correct. [Code]

VGN-SR490 Missing Eth0 Ethernet Interface In Ubuntu / Can't Connect To Router

Aug 26, 2011

I'm having trouble getting my Ubuntu 10.04 machine (Sony Vaio VGN-SR490) to connect to the Internet by way of an Ethernet cable connected directly to my router.

I'm able to connect to the Internet using this same cable using a Windows machine, way Linux is configured. [code] It looks like the network adapters list is empty. I will now install both Windows XP and Ubuntu Linux dual-boot. I'm still not able to access the internet, even through Windows. I'm wonder if this could be a hardware problem with the computer or a problem with the router itself. Other computers can connect to this same router, and work fine.

Cisco WAN :: 1811W Accessing Web Interface On ADSL Modem In Bridged Mode

Nov 8, 2012

Using Cisco 1811W with IOS 15.1(4)M5.  FE0 and FE1 are connected to the internet via Billion ADSL2+ modems operating in bridged mode.  Both lines are similar so I'll only discuss FE0 from this point on.Local subnet is 192.168.128.0/24 with router on 192.168.128.1 as default gateway.  Modem on FE0 has static LAN IP of 192.168.128.2 and when plugged into the switch on the LAN side, the web interface can be accessed at that IP address.  Unplug the modem from the switch and plug it into FE0 and it now works as desired providing access from the router to the internet but the web interface is no longer accessable at 192.168.128.2
 
I tried adding a static route "ip route 192.168.128.2 255.255.255.255 FastEthernet 0" and also "ip route 192.168.128.2 255.255.255.255 Dialer 1"  Neither worked and presumably it isn't that straight forward.  Possibly NAT or other routing configuration required.Although there isn't much to configure when in bridged mode, I mostly want this setup so I can look at the ADSL connection status and for the modem to write messages to syslog (works when plugged into switch on LAN side), or SNMP access.

Cisco Switching/Routing :: 877W ADSL Line Interface Not Initializing?

Jan 19, 2012

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?

Cisco WAN :: Track Interface On Ethernet Circuit 2900

Apr 22, 2012

The only option that I have under the IOS that's installed on a 2900 series router is track. I don't have a version that supports SLA. The interface is connected to a switch that the ISP gave, and all of the tests that I've done refuse to make the circuit go down. If I were to lose the circuit, the interface won't show to be down unless the switch were to go down.
 
Is there any way with track to see that the provider's circuit went down on a switch? I was going to set up sla to ping the ISP's address, but I can't do that unless I upgrade the OS. These are a pair of routers running hsrp at a remote datacenter. Is sla the only way that I'm going to be able to accomplish this? I have tried track with different options in gns and all of them keep the CE's interface up and doesn't show it down. Watching a route in the table isn't feasible because I wouldn't want it to fail over because another site is having problems. Tracking the route doesn't work for connected routes either because the route itself doesn't leave the table as long as the interface is up.
