Hi,

When i restart the switch i am getting the error to start the switch

switch: boot

Post the complete output to the command "dir flash:".

Hi

did it go into rommon on you ?

have you initialized the flash

If that's already done the ios maybe corrupt and a new one will need to be uploaded to the switch but try the bwlow if you haven't already , turn flash on check the fklash image is there and try boot again

If that fails you will need to try xmodem a new image to flash in rommon then boot again

https://supportforums.cisco.com/blog/151336/loading-ios-switch-xmodem

Try these steps below its same for a 2960

Proceed to Step 2.

Issue the flash_init command and the load_helper command.

If the Flash has already initialized, you see this:

switch: flash_init
  Initializing Flash...
  ...The flash is already initialized.
  switch:

If the Flash has not initialized, you see this:

switch: flash_init
Initializing Flash...
flashfs[0]: 21 files, 2 directories
flashfs[0]: 0 orphaned files, 0 orphaned directories
flashfs[0]: Total bytes: 7741440
flashfs[0]: Bytes used: 4499456
flashfs[0]: Bytes available: 3241984
flashfs[0]: flashfs fsck took 7 seconds.
...done initializing flash.
Boot Sector Filesystem (bs:) installed, fsid: 3
Parameter Block Filesystem (pb:) installed, fsid: 4

Issue the load_helper command in order to load any boot helper images. Here is an example:

switch: load_helper
switch:

Issue the dir flash: command in order to view the contents of the Flash file system.
Determine if there are any Cisco IOS® image files or image directories in flash:. The Cisco IOS image files are .bin files, and the image directories are named with the image filename, excluding the .bin extension. If no Cisco IOS image files or image directories exist, you see this:

switch: dir flash: Directory of flash:/ 2 -rwx 5 <date> private-config.text 3 -rwx 110 <date> info 4 -rwx 976 <date> vlan.dat 6 -rwx 286 <date> env_vars 26 -rwx 1592 <date> config.text 8 drwx 1088 <date> html 19 -rwx 110 <date> info.ver 4393472 bytes available (3347968 bytes used) switch: !--- No Cisco IOS images or image directories exist in Flash.

If your Flash directory looks like this, proceed directly to Step 4. Step 4 recovers the switch with an Xmodem file transfer.
If there is still an image in Flash, issue the boot command in order to try to recover the switch. Before you issue the boot command, verify where the Cisco IOS image is stored in the Flash directory. The location in which the image is stored can differ, which depends on your switch model.

Catalyst 2940, 2950, and 2955 Flash file system

The Cisco IOS image file (.bin file) always resides in the flash: directory on Catalyst 2940, 2950 and 2955 series switches. Here is an example:

switch: dir flash:
Directory of flash:/
3    -rwx  2888547   <date>               c2950-i6q4l2-mz.121-13.EA1.bin

Catalyst 2970, 3550, 3560, and 3750 Flash file system

The organization of the Flash file system on a Catalyst 2970, 3550, 3560, and 3750 is a little different. You can store the Cisco IOS image file in the flash: directory. However, if you use the Cluster Management Suite (CMS) image in order to manage switches with a web interface, you can store the Cisco IOS image file in its own directory. Issue the dir flash:directory command in order to display the image file in this case.

switch: dir flash:
Directory of flash:/
2    -rwx  976       <date>               vlan.dat

SUBBAIAH ARAVETI · ‎05-04-2017

Thank you for response

If we give switch: set BAUD 57600 this command with space it is not accepting

switch: set BAUD57600 while giving this command only this working

Mark Malone · ‎05-04-2017

oh sorry its the I/O error :)

have you tried set the baud rate to a different value , try it a bit slower maybe 38400 , 9600 will take forever so work down if its crashing at 57600, it needs to be set in these values below

Standard baud rates include 110, 300, 600, 1200, 2400, 4800, 9600, 14400, 19200, 38400, 57600, 115200, 128000 and 256000 bits per second.

there is no image in flash for it too load . did you perform the xmodem , did it complete ?

only your vlan file is left in flash , no image

SUBBAIAH ARAVETI · ‎05-04-2017

Hi Mark,

Yes we tried to load the IOS the xmodem through tera term by using your document(link) which is given in above conversation

but we got the below error

switch: copy xmodem: flash:c2960-lanbasek9-mz.122-55.SE11.bin
Begin the Xmodem or Xmodem-1K transfer now...
CCCCCCCCCCxmodem:: I/O error

Mark Malone · ‎05-04-2017

Ok so there is no image in flash there is no point trying to boot as there is nothing to boot

if you have tried all the Baud rates and its failing for each one the flash itself maybe corrupted on teh switch if thats the case the switch is useless and needs to be replaced through RMA

try baud rate 115200

xmodem is the only way to get a image onto a 2960 in rommon tftpdnld is not available as another option as far as I know

heres a video of someone doing it through xmodem for 3560 which would be same concept and commands for 2960
