|
I have a cisco 2501 Router that i used this past year as part of my ccna
study curriculum. I have not used the router in 6 months or so. I have
graduated school and now i am persuing my ccna certification. I fired up
the routers for the first time in forever ( i also have 2, 2524 models no
problems with either) upon examining the 2501 i noticed that it now boots
to boot mode ie: Router(Boot)# I checked the ios and it says the checksum
is invalid, so I decided to upload a backup of the ios from my pc via tftp
server. The router has 3 interfaces 2 serial and 1 aui, since i do not have
an aui transciever I always set up a serial connection from my 2501 to my
2524(which has an ethernet interface) and copy or upload the ios from my pc
to the 2524 and on to the 2501. I would like to have done it this way
however I could not get a connection accross the 2 routers. The 2501 would
let me get to the interface, set the ip, no shut, and the clockrate,
however i could not enable rip (it says invalid command), i have used the ?
command and the router (protocol) command is not listed anywhere. So I
decided to send the new flash via xmodem from rommon mode to the router. I
entered config-register 0x2100 and reloaded only to find that I am now in
what seems to be an even less functional version of rommon mode. When i
reboot the router I recieve the following info:
System Bootstrap, Version 11.0(10c), SOFTWARE
Copyright (c) 1986-1996 by cisco Systems
2500 processor with 6144 Kbytes of main memory
Upon typing ? at the prompt I recieve the following options:
$
B [filename]
C [address]
D /S M L V
E /S M L
G [address]
H
I
K
L [filename]
O
P
S
T function
Deposit and Examine sizes may be B (byte), L (long) or S (short).
Modifiers may be R (register) or S (byte swap).
Register names are: D0-D7, A0-A^, SS, US, SR, and PC
when i try to reload the router I recieve the message:
What?
Ive tried to change the configuration Register to 0x2102 and the command
seems to work but there is no way (I cant find it) to reboot the router
except to turn off the power.However when i power back up im back to the
same screen =(
My questions are
1. How can I get back to regular ROMMON mode?
2. Once in Rommon or boot mode is there anyway to bring up a serial
connection to another router ( since the protocols seem to be disabled)
3. Can I upload the flash image while in this mode and if so how
Thank you in advance for your help, and if you require any other info
please feel free to ask. Thanks again |
