Cisco 2500 updated IOS
|
|
|
| Does anyone know where I can get an updated IOS for my cisco 2500
besides the cisco web sight. I am trying to get certified with a
router that I borrowed from work but it has IOS version 9.
| |
|
| In addition to the IOS you'll probably have to upgrade the Flash, RAM and Boot ROMS.

Paste the show ver from the router.

| I had version 11. something cant remember exactly but I was playing
around with the router and typed erase startup-config then I rebooted.
I tried all kinds of things and when I rebooted it tried to load
strange files like s;ldf;f.bin and sdkfd.bin. I guess when I was
playing around I told it to boot to those files, which don't exist.
In a nutshell I screwed the whole thing. I'll try any version greater
than 9, I think. When I type show version this is what I get:
Router(boot)#show version

I pretty sure that the '4' in 0x141 means that you boot from the ROM image.
Have you tried setting this bit in the configuration register e.g.
#config-register 0x101
#reload

Set the config register back to 0x2102 after you checked with the "sh
flash" that there is still an image available.
||Router(config)#config-register 0x2102
The factory default value for the configuration register on 2500
series routers is 0x2102. This value is a combination of the
following:
bit 13 = 0x2000, bit 8 = 0x0100, and bits 00 through 03.
Bit No.1
Hexadecimal
Meaning
00 to 03
0x0000 to 0x000F
Boot field (see below [1])
06
0x0040
Causes system software to ignore NVRAM contents
07
0x0080
OEM bit enabled
08
0x0100
Break disabled
10
0x0400
IP broadcast with all zeros
11 to 12
0x0800 to 0x1000
Console line speed
13
0x2000
Boot default ROM software if network boot fails
14
0x4000
IP broadcasts do not have net numbers
15
0x8000
Enable diagnostic messages and ignore NVRAM contents
[1]
Boot Field
Meaning
0x0
Stays at the system bootstrap prompt
0x1
Boots system image in system ROM
0x2 to 0xF
Specifies a default netboot filename Enables boot system commands
that override default netboot filename
Remember the lowest four bits of this value are the boot field.
0 = manually boot (ROM-Monitoring input)
1 = boot from skeleton IOS in ROM (very basic IOS you currently have)
2+ = boot from default IOS-image (mostly flash, but maybe TFTP-server)

The '4' means: "Don't use startup-configuration from NVRAM".
The '1' is what you mean.

Don't need your book. Posted a somewhat comprehensive description of
the config register values ;-)
