Cisco 2611 - No Console Output
Jan 26, 2012
I was given an old Cisco 2611 to screw around with, no idea if it's working or not and no idea if the configs and passwords were wiped. Now my problem is that when I turn it on I don't see any console output at all.
Using 9600 baud, 1 stop bit, 8 data bits, no parity or flow control.
The power LED comes on and the activity light blinks for ~1 - 2 minutes before stopping. If I plug something into one of the Ethernet ports on the back the link light comes on for the port and the activity light occasionally flashes, from DHCP probes or something from my netbook I assume.

I have a 3560-24ps, and I'm having issues with it booting. When I power the device up all the front panel lights come on like normail, and then the system light starts flashing like normal, but after 5 - 6 seconds the system light goes off. I don't get any output from the console, and the fans still run.

A broadband speed test take before the Cisco 2611 shows 25+ Mbps. After the 2611, it drops to under 6. Consistently. The router routes between the local LAN (10.80.0.3) and a remote building across (10.13.0.2) a T1. The ADSL internet connection enters this router and leaves to a Cisco 3550 switch.

We have an aging 2611 router that that we need to replace due to the fact that its 10Mb/s Ethernet ports are limiting our internet connectivity throughput (we have a 20Mb/s circuit).
The purpose of the 2611 router was to route traffic from multiple devices connected to a 2950 switch's VLAN X to the internet. Can we achieve this same functionality with only a 3750C-48TS-S switch? Could a static route statement on the 3750 replace the need for the router?

I'm trying to connect my Cisco lab to the internet. I've configured my 2611 to accept DHCP. I can ping the Linksys E1000 router but can't ping the modem on the other side, and cannot get out to the internet with the PC that's connected to the lab. When I look at the DHCP table in the E1000 the 2611 shows up in the table. I can ping all other computers on the lan, just not the modem to get out to the net.I have the configuration for the 2611. Did I miss something. Is the modem blocking ICMP traffic?

I have a wireless access point, I want to be able to hand out addresses via the Cisco router through DHCP on the interface eth0/1. The wireless users that get an IP I want then route out the eth0/0 interface to my statically assigned default gateway. Right now Im not concerned with setting up security measures once this works I'll go back in and add that. Here is my running-config. Right now nothing from the 10.0.0.0 is being routed out to the internet.

I am with Virgin media and have a home lab (2611 routers, 3550 switches, 2950s etc) which i usually just use for testing things on and practicing.
Now I tried to connect it to the internet and got some weird things happening.
I got NAT and DHCP client all setup correctly on the router (or so I think!) along with DNS settings but I still can't get Internet access.
My network is all setup right so that through using OSPF the router is the gateway (0.0.0.0 route) for all devices. Doing a traceroute confirms this.
Yet I never get any further than the router? I see IP nat translations ticking up as I send more requests but never get a webpage or a reply from any of the machines in my network.
HOWEVER... The router itself does get some replies from Google.co.uk and bbc.co.uk but doesn't seem to want to give anything else on the "inside" a response?
Here is a dump of config:

My home lab is in a different room than the cable modem. I have a wireless N router in the room with the cable modem. I have a wireless access point that is connected to a Cisco 2611XM routers fa0/0 interface. The 2611 accepts the DHCP address from the wireless router. However, I can't ping past the wireless LAN 192.168.10.0 network. I know with the wireless router it's two layers of DHCP. Should remove the DHCP settings from the wireless router? The wireless router is a TrendNet TEW-651BR. I can ping my iphone or any device conntected to the wireless router. And my laptop can ping default gateway of the wireless router, which I assume is the cable modem, however the 2611 cannot. So I'm assuming that's why the hosts behind the 2611 can't get to the internet. I followed the below instructions. I know the instructions don't assume your using a wirelss router between 2611 and the cable modem. But, I really don't want to run a cable to the cable modem.

I have 1 2611xm router and 1 2801 router. For my own lab purpose, i want to configure them back to back to support voice services. I don't know what configuration will be required at each end. in 2611xm, i have NM-2V and its also detecting the card, so i hope it will work ? also what commands i need to run on both ends .

I'm in an issue w/ on of our ISPs. We're using an ADSL line as a secondary light load line ( 16 MBit, /w PBR in place to separate the 80 and 443 from the business-critical applications running via a SDSL link. ).
I am on a 2611 XM with IOS 12.2, mated to a D-Link 321B modem running in transparent mode. After running smoothly for weeks, for a few days now, every night some time between 2 AM and 4 AM the link would die with the dialer showing:
Virtual-Access1 is up, line protocol is down Hardware is Virtual Access interface [code]....
To my knowledge, the only option to bring it up again is to reload the box . Taking into account that the router is our DHCP server and the date gets reset to 1994, interesting effects are the outcome of resetting the box.
Well, the ISP have checked their gear and keep saying that these report a "port error" ( quite unspecific ) and blame me that I have a wrong. config in place - which is here:
interface Dialer2

I want to watch internet streaming on my TV. And I don't want to have my PC turned on all the time. I've learned that I need some set top box for that, so I could connect it to my cable modem and TV. But all set boxes I've seen so far are for HDTVs and my TV is standard with S-VIDEO input.

I have an issue with an ASR 1001. The problem occurs with MQC shaping applied to a gigabit interface in the outbound direction. The CIR of the provider we are using is 100Mb/sec, so we are shaping to that value. However when reported traffic levels are about 60Mb/sec, we see a steady increase in output drops. [code]
I have also tried increasing the hold queue, however this does not work with the drops. Increasing the shaping rate to 200Mb/sec gets rid of almost all the drops (not quite all!) but is not what we need. I think that we should see some drops when rates spike above 100mb, however the amount we are seeing seems excessive?

I am looking at the interface stats of port Fa1/0/2 and see something strange. Ouput drops are 42Billion in 16mins, then 21249 few seconds later, then followed by 42Billion drops again, then 21444...and so forth..I keep getting an entirely different output drops reading everytime i refresh within seconds of each refresh!

we installed two weeks ago a 867VAE-K9 as a border router for a medical practice.It's got two vlan interfaces for inter-vlan routing, only one Gi interface up in trunk mode to the core switch and the ATM for ADSL2+ connection to the local ISP. A cisco wap is on the secon vlan for the patients. There is a voip pbx on a linux machine that registers 5 trunks to an external provider (only one trunk is used right now, and it works fine).(Almost) everything works fine :-) Sometimes (it can be hours or days) the routing to the internet stops. The meds can still use the LAN accessing everything in it with no lag, and the patients can access the isolated SSID on a Cisco wap on the second vlan. They simply cannot surf the internet.
- DNS and local routing is fine
- the router is reachable through the Gi interface
- they can send and receive traffic to and from the 867 vlans' IPs
- the ATM, dialer 0 and virtual access are up, line protocol up
- the dialer has got the IP address negotiated from the ISP
- default route is negotiated through ipcp
- the controller vdsl 0 is in showtime! state
- from the outside we can ping the PPP peer, but not the IP of dialer 0
The only thing is the queue counter of ATM which shows drops and total output drops. Attenuation is fine, noise margin not so well. The point is that outside traffic to the internet is at low levels and the routing almost always stopped when no one was using the internet (i.e. out of office hours). It already happened 7 times in 16 days. The problem obviously is that voice traffic is impaired by the stuck router, and no med there is able to ssh into the router and re-activate the atm 0 with a shut/no shut.
It is not necessary to reload. A fast shut/no shut of the atm0 (no wait between the commands) will make it running again.We're activating the smarnet for this router to update dsl fw and ios image, but I thought I could post here before that.[code] As a brutal workaround till the update/fix, I was thinking about monitoring the reachability of some external systems and use snmp from the lan to shutdown/no shutdown the atm (though I don't even know if that would be possible from snmp on this router).

I have this topology in part of my networ:k
Cisco7200---Cisco6500---Cisco3560---LAN1
|
Cisco3560
|
LAN2
All devices are interconected via optical 1Gb/s links. There is no QoS implemented on any device and all VLANs are allowed on all interfaces.
Also all links are trunks (with many VLANs)
In LAN1 there was a layer 2 broadcast-storm and 4000packets/s was comming to rest of the network (in one particular VLAN).
1) 7200 with G1 should be able to handle traffic up to 500Mb/s, but a lot of users experienced drops on traffic via 7200.
(CPU load was around 10%).
2) Why do I have input drops on 7200 on link toward 6500 if CPU was normal. Broadcast comming to this interfaces were cca 4kpps. But since it's destination is not on router these packets should be rejected on interface controller. Is that right? (7200 doesn't even has dot1q subinterface in that VLAN but since 6500 allow all VLANs on its trunk these packets reach 7200)
3) Why do I have output drops on Cisco 6500 (it is here as layer 2 device only)? It is max 160Mb/s in output direction. It has WS6724 card with DFC (there is no oversubscription).. Shouln't 6500 send traffic as fast as interface allows (up to 1Gb/s). Am I righ't?
4) After all how coul'd 6500 now if 7200 can't handle these traffic?Output drops should be only seen if QoS is enabled (i.e. shaping), or if there is oversubscription on the linecard?

I have a Cisco 2821 with ios Version 12.4(21). On that router I have a WAN link that is 550mbit dual. The interface is 1000FD so i need to shape my output traffic to max 550mbit - otherwise my ISP policing is dropping the traffic.
I've looked at this document url... and i'm trying to use this interface command:traffic-shape rate
But the router wont accept rate value 550000000 that should be 550mbit in bits/s
Is it not possible to shape the traffic to 550mbit on the 2821 router?
