I have a remote customer who is having issues with their 3825 router - since I can't be on site troubleshooting is difficult but so far all that seems to happen when the device is powered on is the "SYS PWR" light goes solid green, and no other lights come on. Fans seem to be operating normally. Console access doesn't appear to be working.
we have a problem with a Cisco 1841 router while booting. The router is loading the image from the CF card but gets stucked at this point:

I have 7604 router with FWSM module in module 3.First of all the FWSM CF has been damaged, not physically. I bought the new same compact flash (size, partnumber, etc.). Downloaded the software 3.2 for FWSM, and ASDM from Cisco website. I realized that the procedure of creating new CF for FWSM is quite diffucult: creating 1-5 partitions, where 1 - is MP, and 4th - application partition. According to cisco documentation - the default boot partition is the 4th, so I partitioned from 7604 the CF into 4 partitions (partition disk1: <1-4> maximum) and copied the software and ASDM to the 4th partition (disk1:3:). Removed the CF from the router and put it into the FWSM module.
I've tried to upgrade firmware through chrome, but chrome abruptly shut down during upgrade.Since that, I have not even loggin set-up menu which should be shown up putting 192.168.0.1 to make it back. Amber light is just blinking on Power lamp.
I have a 3825 router running 12.4t IOS. I installed DSU/CSU part number HWIC-1DSU-T1 in the router and it does not recognize it. Is this the right card for this router? Is there anything I can look at to determine the issue? I think the router only has 32M RAM. Below is a show hardware. Card is still currently installed.
I wanted to upgrade our three WLC 4402 from software version 5.0.148 to 18.104.22.168. The upgrade on the first controller was working. Unfortunately he lost all the local management users and it's MAC filters, but restoring this was not the problem. After upgrading the second controller.... the device does not boot anymore! The alarm led is RED and I don't know what to do. The only way to get connected to the controller is via the console port. There I can see a "parse error" but I don't know if that is the problem. Please look at the "log" attached. I'm not sure if the red alarm led was there before upgrading the controller software because the device is located to another place. I'm really concerned about upgrading the third controller because it's the most important wlc.
Last night we had some pretty bad lightning and thunder and our Linksys WAG160N appears to have had a bit of a fright.As I was going round unplugging items in case of a hit (this was after a flash or two, relatively nearby), all the lights on the router were off except for the ethernet light (plugged into a Linksys homeplug adaptor). Now the router doesn't appear to boot. When powered on, the power light doesn't flash or anything to indicate booting up, all you get is the ethernet light (if connected) after a few seconds, but no activity. I'm presuming something has been fried or corrupted? I'm not sure if we did have a power spike either through the mains or phone line as all other equipment seems to be fine, but I'm wondering the the homeplug connection might of had something to do with it after reading a few posts from others on the subject.I've held in the reset button while starting and it doesn't appear to have done anything. I will try the 30/30/30 reset tonight.
Due to a problem with POE+ i have tried to upgrade the IOS to Version15.0.2SE2, from 12.2.58. unfortunatly the Switch doesn't boot up anymore. It starts to decompress and install the IOS 2 Times, after the Second try it displays "unable to boot" and the switch goes in Bootloader-mode. When i look at the version i See that bootloader is still the old version 12.2.58. It seems that the bootloader doesn't geht upgraded and that's why the Switch can't Boot the new Image.
We have small network with 15 Computers all connected to SRW224G4 . After a power brake our switch dosent "boot" anymore. I see all leds working flashing etc but no network acces, no Serial acces. When i try connecting to serial port and "reset" device the screen is blank.
The process is IP Input and I'm not really sure how to troubleshoot it. I've read through all the doc's on high cpu load if I shutdown the port that feeds that network, CPU drops to around 30%, bring it back up and it jumps up to 90%+. I've got a policy map on the interface shaping the traffic [code]...
I am trying to upgrade the IOS on cisco 3825 from 124-9.T1.bin to 124.24.t6.bin, after I upload the configuration to the CF and verify the file, everything appears fine but when I try to load the new image it fails with following error and falls back to old image :-
System Bootstrap, version 12.3(11r)T2, RELEASE SOFTWARE (fc1) Readonly ROMMON intializedboot: cannot open "flash:" an alternate boot helper program is not specified (monitor variable "BOOTLDR" is not set) and unable to determine first file in bootflash loadprog: error - on file open boot: cannot load "c3825-advsecurityk9-mz.124-24.T6.bin"
Then after few minutes it boot to the Old 12(4).9 ios again.
What are the prerequisites before doing this? I have to upgrade a router this Wednesday evening if there is an opportunity to move it to a code that is more current that the one the client is currently running which is 12.4(25b). I see on the Cisco Support site that after this code, everything moves to 15.
I have a 3825 with a 16 port etherswitch card installed that I'm trying to setup rate-limits on. Interface G0/0 is the connection to the outside world and int g0/1 has a couple of 2950 switches attached to it.
The etherswitch card, f1/0, f1,1 etc has corresponding vlans, 902, 903 etc each with an IP 10.110.1.x, 10.110.2.x and all part of access-group 111. The switches connect on sub-interfaces g0/1.101, g0/1.102 etc and have IP's 10.55.1.x, 10.55.2.x and part of access-group 101.
What i'm trying to achieve is that every port / IP that is on access-group 111 shares 3Mb of bandwidth in/out and access-group 101 shares a separate 3Mb of bandwidth in/out.
I've created two access-lists as follows;
access-list 101 permit ip 10.55.0.0 0.0.255.255 any access-list 111 permit ip 10.110.0.0 0.0.255.255 any
And on int g0/0 I've created the following rate-limits;
Is there any way to configure 3825 to ensure that all packets have a source IP address that matches the correct source interface (similar to ASA's 'ip verify reverse-path interface')? Currently, we manage anti spoofing with a bunch of ACLs, however I'm looking for a more manageable solution.
This is a multi site network. Site A has a Cisco 3825 router and connects to 3 other sites over ISP A and 2 other sites over ISP B. Both ISP A & B provide a layer 2 full mesh network. ISP A provides a 100mb pipe while ISP B provides a 20mb pipe.
File transfers (Windows - CIFS) over ISP A's fiber are fast enough and throughput is good. However, file transfers (Windows - CIFS) over ISP B's fiber are slow, even though latency is good. On the 100MB ISP A pipe, file transfer speeds up to 6 M Bps are achieved. On the ISP B 20MB pipe, speeds up to 300KBps are seen for file transfers.
ISP A connects to an on board gig port on the 3825. ISP B connects to a fast ethernet port on an HWIC-2FE card on the same 3825. Both ports then connect to ISP Switches and then full meshed to remote site Cisco routers. What could be the issue? Why am I facing these issues only with ISP B even though the configs for ISP A and ISP B are the same?
I have 3825 router with flash size 128 and 512 RAM.i am trying to install a VIC3-2FXS on the router.the FXS is know by the router when i put show version or show diag,unfortunately the FXS is always showing orange light.i tried to upgrade the router to c3825-advipservicesk9-mz.124-20.T.bin and to c3825-advipservicesk9-mz.151-1.T3.bin with same result.
I have a 3825 with a 1Gb fiber card at one of my sites. Our ISP and MPLS provider hand off a single gigabit fiber to us that contains 2 50MB EVC's.I need to apply QoS to one of the EVC's and shape them both to 50Mb to avoid upstream rate mismatch bottlenecks. Both of the EVC's generally only push 10Mb during business hours.When I run UDP stream tests (various rates from 500k-6m that are marked as AF41) to one of my other sites I am consistently getting about 2% packet loss, despite the fact the circuit isn't even close to 50% saturation. When I remove Shaping and QoS all together, the issue nearly clears itself up, except during peak hours and I get small bursts of packet loss, which is still unacceptable.When the pipe is at near zero utilization (after hours) there also is no packet loss with or with out the shaping/qos applied.
We use a 3825 router to screen alot of the junk from the internet side or our firewall. Its worked well for the last 4 years buthas rebooted multiple times in the last month for no apparent reason.At this point I think I would prefer to replace it.Our current internet link is 100Mbps and this router handles that quite well. Is there an equivalent that I should replace it with, or should I just buy another 3825 ?One with an OOB management port would be nice.
I want to build up cisco 3800 series router as terminal server , i have Asycs 32A module in cisco 3825. Here is show version of device.Do i need to installed any specific IOS in Cisco 3825 device ? how to configure cisco 3825 as terminal server.
I have a 3825 configured as an EZVPN server with 881 routers as clients. One issue I am seeing is that sessions don't seem to time out, such as when a peer's public IP changes. Show crypto ISAKMP peer shows the same host (using device certificates for authentication) with multiple public IPs establishing sessions. I have ISAKMP keepalives configured on the router.
I have a NMWLC6 module connected to a 3825 ISR using 1140N APs. Latest (but one) code. I had two SSIDs configured and deployed in the default AP group. Last week I needed to deploy a third SSID for unencrypted webauth, I created the interface and WLAN associated with the interface and the sub interface/svi on the WLAN-controller 0/1 with dot1q. All created with no problem and enabled, however the SSID was not available to clients and did not show up as available WLANs under AP groups menu. Out of desperation I created a new AP group and added an AP to it and hey presto all three WLANs were available and the third is now visible to clients! Is this normal behaviour? Is the default AP group limited to two SSIDs? (a quick google failed to find any documented limitation!) or is something weird going on?
I have three Hub routers that I'm wanting to compare DMVPN scalabiltiy capabilities (3825 versus 3945 and 3845). I know it must be there somewhere and I'm just not looking in the right place. But I've read and read and read about DMVPN designs and I'm not finding anything. This is turning into a time killer. What are the DMVPN limitations of these three routers are?
What is the maximum amount of traffic a 3825 router can take. I know that a 3825 is rated to handle half of a DS3/T3. We are planning to put a 50Mbps point to point metro Ethernet circuit between two 3825's and run encryption over that line. I just want to make sure we don't max out the router as I remember once a customer maxed out a 3825 with a ton or GRE tunnels and the router crashed every time they did their nightly data dump.
