Cisco WAN :: AS2511 Stuck In ROMmon?

Oct 1, 2011

Im trying to upgrade my IOS. It wasnt at ROMMON before but I thought I can upload the IOS on the xmodem so i did a

conf t
config 0x0
reset / reload
Now that I am in the ROMMON. If i type CONFREG to change the BAUD,  nothing shows up. Usually it gives options but this time, nothing.

So I tried to go back to the normal CLI

I turned on the router manually and turn it back on hoping that it will work but it brought me back to rommon.

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 Firewall :: ASA5505 Transparent Mode Not Working

Feb 19, 2013

I have a cisco ASA5505 configured in transparent mode. This evening we attempted to plug a couple of new servers in but they simply didnt work, despite our test server working absolutely fine. The server IP's are all in a network object group (the same as the test server) and they're all using the same ACLs etc. I'm relatively new to configuring cisco equipment.
the only thing I can think of is a static route I had to add to get the managemet IP to work might be causing problems.route outside XX.XXX.132.1 1(IP addresses obfuscated- servers are all in the same range so assume XX.XXX is the same across all IP's).

Cisco Switching/Routing :: Cannot Get Out Of Rommon Mode 1760

Dec 10, 2011

I'm currently pursuing to take my CCNA and am currently studying for it, but have recently encountered a problem with one of my 1760 routers that I can not solve.Yesterday I went to boot up my router like normal, however when I went into hyperterminal I noticed the router was in Rommon mode. Thinking I could change the configuration registry, I tried to bypass the NVRAM by using confreg 0x2142. However this still causes the router to go into Rommon mode. I am getting an error that states that there is insufficient memory to load the IOS image. [code]
I have used the dir flash: command and can see the IOS image, and try to boot from it (boot flash:iosimagename) but it will still go back into rommon mode. I also just swapped the RAM from my other 1760 into this 1760 and it booted up and went into normal configuraiton mode without any issues. However, the other router now will not load it's IOS image and I get the exact same error.I'm at a loss here, and have searched to figure out where or how I can just wipe the router clean to try and start fresh, but cannot get out or Rommon mode. The only thing I can think of is that the RAM went bad since it wont boot up either machine.

Cisco Switching/Routing :: 3550 - Copy IOS To Switch In ROMmon Mode?

Jan 24, 2012

I have a 3550 switch that was replaced at a remote site with no IOS. This is a switch not a router so tftpdnld does not work.
The problem is the switches interface never comes up so try to connect to the tftp server. I read on google it can't be done on a switch to copy from tftp to flash in rommon mode on a switch and to use XMODEM. My problem is I do not have access to it, I ssh into a 3640 which is an access server for all devices and that is how I have console to it, how to use XMODEM over ssh.
But I'm fairly certain that there has to be a way to just copy it from tftp? I have a 3550 local and when I put it in rommon mode it stops the port check at port, port 1 goes from green when you plug it in to off then port 2 changes to amber and the rest green. So just by the look of this I would believe tftp would work; you just need to use port 1.

Cisco :: 2951 - Access Server Not Displaying ROMmon Mode Target Device

Sep 17, 2012

I'm configuring a console server for configuring remote devices. This is working well except for the fact that if a target device is in ROMMON mode, the console server refuses to displays the target device console. It does open the connection but the ROMMON prompt is not shown on the console server . This is essential for this device as we will need to use it to reset passwords remotely and thus need to be able to access ROMMON mode from the console server.

Parts used are a 2951 router and a HWIC-8A serial card. Posted my config below:
Current configuration : 4389 bytes

The  model is a WLC  5508-50k9 model wireless controller and software, I  have seen as per installation guideline that  amber means th following
Distribution ports 1-8 Off: Not present.
#Green: Indicates SFP port is active and link is established.
#Amber: Present with failure
This mean that so coherent fault lies as follows on Layer 1&2 . The switch port light does not go green either. We have used both xover and straight but no luck

Cisco AAA/Identity/Nac :: 2960S Switch-port Stuck In Guest Mode?

Mar 18, 2012

I am using 802.1x authentication with multi-domain ports; Phone and PC connected to phone. The phones are Nortel (Avaya) and the PCs are Dell/HP Laptops. All are configured for Certificate authentication and this works well. However we sometimes get some ports stuck in Guest mode. when a non certificated laptop connects to a phone port and fails authentication, the data port is placed in the Guest VLAN. However when the laptop disconnects the port isn't reset and remains in the guest state. When a subsequent good laptop connects and attempts to authenticate the switch ignores this and leaves the data port in the Guest VLAN. he switch is a 2960S with Version 12.2(58)SE2 IOS.
The port is configured as follows:
interface GigabitEthernet1/0/15
description DANS Port
switchport access vlan 1807
switchport mode access
switchport voice vlan 1855
priority-queue out


I placed the AAA, dot1x, eap and auth debug on for all events and then connected a good laptop, the only debug message I got were as follows:
Mar 19 16:17:01.391 GMT: AUTH-EVENT (Gi1/0/15) dot1x_switch_is_restrictive_vlan_open_auth:Multi-Host with Guest Vlan/Auth Fail Vlan or open aut
Mar 19 16:17:01.653 GMT: AUTH-EVENT (Gi1/0/15) dot1x_switch_is_restrictive_vlan_open_auth:Multi-Host with Guest Vlan/Auth Fail Vlan or open aut
Mar 19 16:17:02.654 GMT: AUTH-EVENT (Gi1/0/15) dot1x_switch_is_restrictive_vlan_open_auth:Multi-Host with Guest Vlan/Auth Fail Vlan or open aut

I would have expected the auth function to have reacted to the EAP packets sent by the good client when it connected and performed eap authentication but it didn't, all it did was say the ports in Guest mode and left the laptop in this VLAN.
