Cisco WAN :: 2800 Series Router IOS Is Not Loading?
May 7, 2013
i have one cisco router 2811 now its not booting normally.
Router was working without any problems but due to power loss router restarted and goes into rommon mode
I tried to boot from flash and usbfalsh with different images but no use router is in still rommon mode.
here the output of my router:
program load complete, entry point: 0x8000f000, size: 0x3117470
Error : compressed image checksum is incorrect 0x8E095E7F
Expected a checksum of 0x8E0AE77F
*** System received a Software forced crash ***
signal= 0x17, code= 0x5, context= 0x80014e20
why I can't use cisco ehwic-3g-hspa-u card in cisco 2800 series and 1841 series router?documentation said that it should work with that devices but when I installed it, it doesn't work even as device i can't see I am using cisco latest ios advance ent. 15.1(4)M4?
I have Router 2800 series Global nating is configured on it.
ip nat inside source list 111 interface Dialer1 overload ! access-list 111 deny ip 192.168.1.0 0.0.0.255 192.168.0.0 0.0.0.255 access-list 111 permit ip 192.168.1.0 0.0.0.255 any
My object is that i want give internet access only for few users ip E.g IPs addresses from range 192.168.1.0-10 can acess intenet access other all are deny.How i do this with ACL .
i have Router 2800 series we are using leased line Connection 8 Pubilc IP.One IP Config in Router FE0/0 IP 101.102.148.91 and FE0/1 192.168.0.0 Local IP.I have 6 Web Server. How to Config other 7 IP address on Web server in the router 2800 series.
I am trying to add WCCP to be configured for websense. My first option seems to be either purchase an IPServices license for the stack of 3750E switches, but i am thinking this will require us to license all three switches in the stack. The second option i am looking at is to do the WCCP configuration on the 2800 router we have on the edge. The problem is both Gig ports are in use, one going to the firewall and the second going to the ISP. My first question would be, which option is better in terms of manging as well as cost of implementing it.The second question is, if WCCP on the router is a better option, what is the add on module i should be looking to get to add the additional ports to hook up the Websense cache.
I have a 2801 running c2801-spservicesk9-mz.124-3g.bin According to the Cisco IOS MIB locator the image supports OLD-CISCO-SYSTEM-MIB I have tried .1.3.6.1.4.1.9.2.1.55 etc to set server IP address and the filename string but without any luck.e.g.
Reason: (noSuchName) There is no such variable name in this MIB. Failed object: iso.3.6.1.4.1.9.2.1.55.a.b.c.d (where a.b.c.d is the server IP)
I have also tried the method similar to that for Cat 3550 switches where you create a table of entries to define the transfer paramaters then activate the transfer (I think the CISCO-CONFIG-COPY-MIB)
Clean up at the end - destroy .14 with the value of 6.
example output : - -- earlier output omitted -- Error in packet. Reason: (noSuchName) There is no such variable name in this MIB. Failed object: iso.3.6.1.4.1.9.9.96.1.1.1.1.4.111 Error in packet.
We have recently implemented Windows Deployment Services on our local network, but everytime we do a multicast image deployment the network get flooded to point of total saturation.
We have Netgear switches and a Cisco 2800 series router. IGMP Snooping has been enabled on all Switches, however, we are unsure on how to implement multicasting on the router.
The whole network is flat - no VLANs over than the default VLAN1. We only want multicasting to work within our local network and does not need to go out the other side of the router as that is the connection to the internet.
How to get the Cisco router configured properly to enable multicasting to not flood the network. It seems that even if we were to image 4 PCs using multicast this is enough to completely get the network flooded.
Also, am I right in thinking that IGMP needs to be enabled on all of the Switches?
I just read the Removing and Installing CompactFlash Memory Cards in Cisco 2800 Series Routers instructions and there was nothing said regading powering down the router. Are these CompactFlash cards hot swappable??
We have an MPLS network to a half dozen remote sites. At our main location we have a 2800 series router. In the routers config are the following lines for QOS. When I go to the routers on the other end of the MPLS, none of them are configured with these same policies. Would these not be in the running config of the 1800 series routers, or is this not setup correct and this should be removed?
Each time I enter show run on my router 2821, it takes ages to display and I have a cpu peak from the ssh process ( I am connected through SSH)
RTR-2821-01#sh proc cpu sorted CPU utilization for five seconds: 96%/21%; one minute: 34%; five minutes: 22% PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process 55 26948 814 33105 74.96% 16.92% 5.87% 323 SSH Process
I'm trying to turn off SSH version 1 & 2 to pass PCI compliance. Problem is, I cannot touch the VPN link between the two offices. I'm afraid the PKI certificate used for the VPN will be deleted if i zeroize the RSA key which seems to be the only way to stop the router responding on port 22.
Here is the stuff from the running config related to the crypto map: crypto isakmp policy 1 encr 3des authentication pre-share group 2 [ code].....
I'm only CCNA so I'm not even sure if the certificate or RSA key is being used for the VPN link, but I can't tell from the running config that zeroizing it would be a good idea and not break the VPN. I'm open to other ways of disabling SSH, as we are able to just connect using a console cable. But it looks like denying port 22 with an access-list doesn't even stop the router from responding to the port.
Is there a way to set static routes per VLAN?Example VLAN 100 sends all traffic to 192.168.1.1 and VLAN 200 sends all traffic to 10.1.1.1. (2800 Series RTR)I have 5 networks that have their own gateway to the Internet via satellite link. Those networks run over the same infrastructure on separate VLANs. They frequently send traffic to each other, which gets sent over a slow SAT link. I introduced a router to the network and would like to set all my hosts default gateway to the local routers sub-interface then have a static route that send all traffic that is not on one of my 5 networks back to that VLANs respective SAT modem to get routed out over the Internet.
In a site we currently have 1 BT provided ADSL link which is currently terminated using their device which I believe is some kind of 2wire device, which is extremely slow due to distance from the Exchange (4Mbps)...We have a growing number of users here and want to install a second ADSL line from BT to give them increased performance.
We have a Cisco 2800 sat not doing much so I was wondering if I could use this to load balance the link? I know BT do not support MPPP so therefore the maximum any user can get will be the speed of a single link (4Mbps)...But basically how can this be done..
Can I leave the two BT routers in place and place the Cisco 2800 behind them, or do I need to purchase two ADSL modules for the 2800 and terminate the connection there?Also once done, what do I need to do regarding actually setting up the load balancing? I have seen this:
[URL]
But am unsure as to how relevant it is? I am not sure I understand what the ACL's are being used for? I just want all users on the LAN to load balance out...
Also I am unsure of this statement:You potentially need to add policy-based routing for specific traffic to ensure that it always uses one ISP connection. Examples of traffic that require this behavior include IPSec VPN clients, VoIP handsets, and any other traffic that use only one of the ISP-connection options to prefer the same IP address, higher speed, or lower latency on the connection.I do not understand why a established session such as a VPN client, would ever traverse the second ISP connection anyway?
I have not done much with business routers, but we have a 1700 series with a WAN WIC-1ENET card with a RJ45 connection. We had a T1 line and will be moving to ehternet. We are going to be moving to a 20MB line, and i just wanted to make sure I have the right connections before installing. We also have a T1 line in another loaton and would be moving to this same 2811 router there as well.We would also like to copy over the configuration from 1700 series router to the 2811 router. Would it be easier to do it by hyper-terminal? Also if we keep the 1700 routers are they capable of using layer-3?
I have a cisco 2821 router and it has an advanceip image in the flash each time on reboot it gives the message software forced crash and checksum error and finally goes into rommon. i tried xmodem and tftpdnld -r but same problem persists. I even changed the CF with a working router's flash but the same problem occurs.I also loaded an ip base image of about 13Mb size and all the same problem repeats with it.
I'm on a wired business network. Some of the machines are Windows 7 and some are XP Pro, but all of us are having issues connecting to web pages, especially pages with lots of pictures. If you refresh it a few times, it may pop up. Some don't ever come up, like weather.com. The server has the same issue, even if you connect it directly to the router.
I am working on setting up a Linksys router for my Dad. I am moderately competent with networking. Anyway, a glaring, and obnoxious problem I am having is everytime I load a page for the router(192.168.1.1), it does not completely load and I have to hit refresh.Now when I try to change the router settings from DHCP to PPPoE, it reloads the page, for whatever reason, and because this router wants to be irritating, it only half loads the page, so I cannot click the "save settings" button.This is what has been done to the router after being reset(red button on the back held in for 10 sec):I turned on the modem, and plugged directly in to make sure I had internet connection.I plugged the modem's ethernet into the "Internet" port on the wireless router.And finally, I plug an ethernet cable from my computer to the 1st port on the wireless router.Nothing else has been changed. I have not turned on any ridiculous settings. This half-loading router pages is driving me up the wall though. I cannot even troubleshoot the wireless connectivity because I cannot make any changes.

There is a website that does not load when the router is in a certain setting. The website I tried to access was url...I have tried the different firmwares and settings and have narrowed it down to the AES encryption.Have tried the original 120328 firmware, works perfectly with all different settings.With the 120822 firmware, it works with all settings EXCEPT when AES is chosen as the encryption method, be it using WPA or WPA2 Personal.
I therefore pinpoint the AES encryption mode in the 120822 firmware to have a bug. I need to use 802.1n with AES, rather than TKIP.Can someone else using 120822, with AES encryption for wireless, verify that this is happening for them too?
have remote routers boot and load a config from the flash card. It seems this is possible if the Flash Class is A, according to the Cisco web site using the
boot config flash:<Config file>
where <Config file> is the file on the flash.
Although this can be applied on 2811 routers, they fail to load the file on the flash card. I've since found that this router type has a Class C flash. So the question is, can either:
Is there a similar process for other classes of Flash cards, specifically Class C?
or
The router flash be set as a Class A to support this functionality,
The preferred resolution for this would be the first as there are many remote routers installed a diverse and difficult locations to visit, should a format/rebuild of the flash fail for some reason.
don't ask to list the output of a show boot or show bootvar, neither of these commands work. The Startup/Running config lists the boot config line.
I have a HG-521 router which is syncing at 8724kbps, but it is slow loading pages. My isp is talktalk .

Having problems with the E1200 when it comes to loading images and vidoes. Text loads fast, but images take several minutes, and for videos - forget about it, takes at least 15 minutes to load even a 2 minute video. I've changed MHz settings and several other settings, but nothing seems to have worked.
It's' my first router (E 2500) one desk top and two laptop and also a Ipad connected, every thing look fine exept for the Ipad.Lots of page not fully loading, I have to reload couples of time to get it full load. and lots of Youtube video said not presently availale but work fine with laptop or desktop.Did not change any seting on the router, I just plug it and used it
I have a WRT54G with updated firmware. Today I saved my configuration to a config.bin file. When I tried loading the file, the admin screen went blank. Now I am no longer able to access either the internet or the router's admin page. Is a hard reset my only option?
When I go to the router setup screen via 192.168.1.1 the screen does not load properly in MSIE or Firefox. Text does not load.The graphics load okay, and the dropdown boxes, checkboxes, etc. Since many of the links are from text, and all of the descriptions, it is impossible to navigate properly. I managed only by using Firefox's Page Info, Links tab and cutting & pasting. A couple of screen captures are available [URL] have downloaded the latest firmware, but while I can get to the Administration page, much less click on, the Upgrade Firmware sub-tab.
I have on Desktop wired to the router which is my main pc. When I access internet the website load really slow, but when I connect the pc directly to Comcast modem, it's blitz fast. My internet speed is 15 Mbps. I have another desktop and laptop. None of them have the problem. What settings I have to change to get back to speed I used to have before.I messed up some settings on the Cisco Connect and accidentally reset the router. After re-installing the router the problem started.
I bought a DIR-655 for my parents after their old router died in a planned power outage. It's a rev. B1 model running the 2.00 firmware. It worked fine initially for a day or two with great wireless coverage, even in the previously low-signal spots in the house.Then the problems started. The router now has trouble loading any website. What you get is instead a page returned from the router saying something along the lines of "network unreachable, please check you internet settings" (I will go there today or tomorrow so I'll update the post with the specific error). Refreshing the page a few times sometimes makes it load, but extremely slow and then the same thing happens again a few moments later. The same thing happens on both wifi and through the router's LAN ports. If I connect a computer directly to the modem it works just fine, as it has always done before getting this router.I have disable QoS, NAT endpoint filtering and the firewall (SPI). I have also set the WAN port speed to 100Mbit/s in the router, to match what the modem is set to (also had issues with the default setting).
