I'm having a little trouble with a router I have got my hands on to practice for my CCNA.Im connected via serial>USB adapter and via XP HT on Win7. Router boots and I then break the boot sequence with ctrl-break. But then it does not go into ROMMON mode. It simply says this:

Cisco WAN :: 1751 Router Stuck In ROMmon?

Nov 24, 2012

I do not have a cross over cable and have to use xmodem. I set the baud rate to 115200 and I can see everything fine. Using Tera Term when you send the file via xmodem it freezes and closes on packet #3 or about 384 bits. When simply clicking the send file button you get the error- 

*** Reserved LVL 7 Interrupt ***
PC = 0xfff0bc98, Vector = 0x500, SP = 0x80004c4c
 
Not sure what to do from here. I have tried everything.Error you get when you boot the router:

Cisco WAN :: Lab Router 2500 Configuration Not Working

Jun 6, 2013

I grew tired of entering my username and password in my 2500 series lab router. So I removed authentication by typing "no username xxxxxx  password xxxxxx".Different than what I expected (removal of authentication), the router still prompted me for my username, it just won't accept anything I type. 
 
I decided to do a password reset, I changed the register to 0x2102 and then typed "i" for Initialize.   It comes back with error "Configuration from version 12.0 message may not be understood correctly."   and then boots to running config with a prompt for username again....right back where I started.
 
why removing authentication by just typing "no username xxxxx password" would lock me out?If I am actually locked out or maybe there is another way to access?

Linksys Wireless Router :: How To Connect 2500 To DSL Modem

Oct 17, 2012

I just moved into a new place with a DSL modem and am using the connection from the old tenant until my internet gets set up a while from now.  I can plug the ethernet straight from the modem into either my laptop or desktop, and it works perfectly fine.  But when I plug into my LinkSys 2500 router, it can't connect.  I've tried rebooting the router, the router and the modem, plugging the modem back in first, plugging the router back in first.  Nothing.  But all I have to do is pull the ethernet cable from the internet port and click it into my laptop, and voila! internet.  My name isn't on the account so I can't call the ISP and see if there are any special connection instructions, but I suspect there aren't any based on just being able to plug a computer straight into it.

Linksys Wireless Router :: Configure Cisco 2500 To Connect To Network

Jun 27, 2012

I have a Cisco 4200 Wireless Router connected directly to my cable modem. To extend the wireless range I purchased a Cisco 2500 Wireless Router.  As the house is "wired," I can connect the Cisco 2500 to the cable modem in a room separate from the Cisco 4200.  My question is how do I configure the Cisco 2500 to connect to the network and provide wireless coverage from both routers.

Cisco Switching/Routing :: 2500 To Show The DHCP Range Of Router

Jul 29, 2012

how can I show the DHCP-range of a router if I don't have privilege level? (not in enable-mode),I can do a "show ip dhcp pool" - this will show me the range which is configured with the network-command.But there are also some dhcp-exclude-addresses which I can't see.... (I did a test on a router with full privilege-access)I need this because I have a router with limited access from our provider.

Cisco :: Recovering From ROMMON On ASA?

Jun 11, 2012

I cleared the flash (disk0) on my ASA and now I'm unable to restore it with an IOS.

When I attempt to load it with an IOS, it appears to load just fine. It even proceeds to restart, but when it boots back up it displays the error "No images in / Error 15: File not found. unable to boot an image" and goes to ROMMON.

My computer's IP is 10.0.0.1. I'm assigning the ASA 10.0.0.254. The image filename is asa724-k8.bin. Here's the output of the environmental variables and the attempted loading of the IOS:

Cisco WAN :: ASR 1002 IOS And ROMmon Upgrade

Jan 10, 2011

I'm trying to upgrade the ASR 1002 we just purchased and am having some issues (this is a new device and is not in service).  I first tried upgrading the ROMMON using the upgrade rom-monitor filename bootflash:asr1000-rommon.150-1r.S.pkg all command, but the upgrade didn't seem to work completely.  When I do a sh platform I get the below output showing 15.0(1r)S: [code]
 
no valid BOOT image foundFinal autoboot attempt from default boot device...Rommon upgrade requestedMaximum upgrade attempts exceeded, continuing with old Rommon...
 
I've also tried upgrading the IOS, but that is not working either.  I tried "boot system flash:asr1000rp1-advipservicesk9.03.02.00.S.151-1.S.bin" command, but that did not work.  I made sure the image was good using the "verify" command and made sure to set "config-register 0x2102".  After I do a wr me and reload the router I get the below errors.

Cisco Switching/Routing :: Cat 6506 Goes Into ROMmon

Nov 29, 2012

I have a Cat6506.  There were 2 Sup 720 in it for redundancy.  They told me they had problems with this thing in the past needing to go out and reboot the machine.  I need to go out periodically because it goes into ROMMON.  I type boot and it comes back up.  One time though neither one would reboot.  I had to take a third one out there and reconfigure it.  Now it is starting to do the same thing.  One thing I did notice is they never connected it to an UPS.  It is plugged strait into the wall with power going to two outlets.  I am beginning to think there are spikes in the power occurring and this is sending it into ROMMON.

Cisco WAN :: 1841 Cold Always Boots To ROMmon?

Mar 4, 2012

we have 55 of the 1841 routers here, and one of them always boots to ROMMON from a very cold (down 1 hour or more) start.  The image on all 55 is c1841-ipbasek9-mz.124-24.T4.bin.  32 MB Cisco brand flash.  Here's what's been done thus far:In ROMMON changed to 0x2102.  Then 'reset' and the image boots fine.  Change config-reg to 0x2102.  Save config.  Reload and image boots fine again.  Wait an hour or more and boots to ROMMON.Boot from ROMMON to USBflash0:   Format the CF then copy over the bin file.  Change to 0x2102 and save. Reload and image boots fine again. Wait an hour or more and boots to ROMMON.Swapped CF with another unit.  Again, works fine to reload, but shut down and restart an hour or more later and boots to ROMMON.  Format this CF and copy over image while on router.  Image boots fine.  Wait an hour or more and boots to ROMMON.In each case of very cold start the configuration register has reverted to 0x0 {why it boots to ROMMON}Tried dx mode with 0x8001.  Nothing seen that is unusual to me, but I'm not an expert by any means.It doesn't seem to a CF card problem, but could be a connection to the CF card and then something behind that.
 
Here is the output of diagnostic boot mode:
 
Cisco 1841 (revision 7.0) with 116736K/14336K bytes of memory.
Processor board ID FTX1231W0JA
