I have the same issue with

aqeel.abbas · ‎02-14-2013

I have issue with Cisco Router 2801's Console Port. My student was doing a lab and he said during configuration, Console Port stopped responding. He was in middle of configuration, so now at present, only telnet is able to login on "R2>" user mode, enable password is not set, so getting "R2>en
% No password set
R2>"

I have tried different terminal software but no output from Console Port, changed the Console Cables, replace with working console cables, change speed (baud) settings. Also tried to connect same console with "AUX" port and got same error mentioned above. AUX Port responds but I am not able to change mode (R2#) because of incomplete running-config. So please tell me if there is way to FIX it. It seems "Console Port" is physically damaged.

You can use the ROMmon recovery procedure.

Use AUX interface end reload the router. During boot press CTRL+BREAK.

When the promp shows rommon 1> you can use the configuration register commands to skip the password check:

rommon 1> confreg 0x2142 You must reset or power cycle for new config to take effect

rommon 2> reset

System Bootstrap...

Router#

Router# copy startup-config running-config

Destination filename [running-config]? YES

882 bytes copied in 2.456 secs (359 bytes/sec)

hostname(config)#

hostname(config)# enable secret new_password hostname(config)#

hostname(config)# end hostname# hostname# copy running-config startup-config Destination filename [startup-config]? YES Building configuration... [OK] hostname#

hostname# conf t hostname(config)# configure-register 0x2102 hostname(config)#

hostname# reload

Dear Daniele Giordano,

Thank you very much for your kind help.

I have only access to Usermode "R2>" and telnet as well on usermode. I can't change into Enable (R2#) Mode. So how can I use ROMmon recovery procedure. Cisco says "during boot process AUX port is disable" so During boot pressing CTRL+BREAK while in AUX Port Connection would not work. Also my Config-Register Settings are:

"Configuration Register is 0x2102" And Cisco says "0x2102

Ignores break

Boots into ROM if initial boot fails

9600 console baud rate default value for most platforms"

Please help me to make Router-2801 alive.

Here's also outuput (via AUX Port, same Console Cable in connected in AUX Port) from few commands, may be helpful to shoot the trouble.

Hi,

Daniele has given you some excellent advise (+5 D)

Have a look at this link re BREAK KEY EMULATION as this

is dependant on your terminal emulation software

http://www.cisco.com/en/US/customer/products/hw/routers/ps133/products_tech_note09186a0080174a34.shtml

I am also copying you the correct procedure document for a 2800 password recovery.

Dear acampbell,

Thank you very much for your kind help. In fact I don't need Password Receovery.

However I tried to press Crtl+Break, and Break, while connected to Console Port, and nothing happened. Only blinking pointer on terminal screen and no garbage value or anyother output from Console port.

My Problem is that Console Port is NOT Showing any Output both in Windows XP Hyperterminal and SecureCRT. I can see the Output when I insert same consoe cable into AUX Port, only giving me "R2>" User mode. And second problem is "enable password is not set". So I have changed terminal software, console cables, speed settings and no success to see the Output from Console Port.

I have the same issue with cisco 2911 router. Suddenly the output of the console session is not showing. If I use the same console cable on a cisco switch, the output will show. This means that the console cable is working. I can telnet into the router but am stuck in the user mode. If I type the command enable ,it will say 'password not set",

How do i fix the issue?

The other problem I have is on the cisco 2960 POE switch. All the ports went down. If I try to enable them, I will get error message " the port cannot be brought up because it has failed power inline test. FIND attached. How doIfix this issue?
