hi

      how to ipgrade ios in 3560 when it is in rommon mode

[paul driver]

Hi Aslam,

The best way is to use a tftp server app on a pc with the IOS you wish to install and connect a cross-over cable between switch and pc.

on pc:

Static ip address - lets say 172.16.1.10 mask 255.255.255.0

on the switch:

rommon:

set

IP_ADDRESS=172.16.1.4

IP_SUBNET_MASK=255.255.255.0

DEFAULT_GATEWAY=172.16.1.4

TFTP_SERVER=172.16.1.10

TFTP_FILE=c3560-advipservicesk9-mz.122-46.SE.bin

TFTP_VERBOSE=2

TFTP_RETRY_COUNT=20

sync

tftpdnld

Hi,

I am not sure if you can use tftpdnld on switches

Follow these steps, these will help u to ugrade successfully.

When the switch is on ROMMON mode, issue these commands,

load_helper

flash_init          --- to initialize the flash memory

dir flash:          --- to see if you already have an IOS in the flash

If you have IOS in the flash then use below command to boot up using that IOS.

boot flash:IOS-name.bin

If you don't have IOS in the flash then use below command to load IOS to flash using xmodem method.

copy xmodem: flash:IOS-name.bin

After its done, boot with new IOS.

boot flash:IOS-name.bin
