Catalyst 2955 Series Switches


If a Catalyst 2955 is in a continuous reboot, you must break into switch: mode by issuing a break sequence from the keyboard.


The break sequence is determined by the terminal application and operating system used. Hyperterm running on Windows 2000 uses Ctrl + Break. For more information, refer to Standard Break Key Sequence Combinations During Password Recovery.


The example below uses Hyperterm to break into switch: mode on a 2955.

Send break character to prevent autobooting.



!--- Wait until you see this message before

!--- you issue the break sequence.

!--- Ctrl+Break is entered using Hyperterm.




The system has been interrupted prior to initializing the

flash filesystem. The following commands will initialize

the flash filesystem, and finish loading the operating

system software:

flash_init

load_helper

Issue the flash_init and load_helper commands.


If the Flash has already initialized, you see the following:


switch: flash_init

...The flash is already initialized.

If the Flash has not initalized, you see the following:

Issue the load_helper command to load any boot helper images, as shown below.


switch: load_helper

switch:

Issue the dir flash: command to view the contents of the Flash file system. If there are no IOS image files (.bin files) or image directories (named with the image filename excluding the .bin extension) in flash:, you see the following:


switch: dir flash:

Directory of flash:/

2 -rwx 5 private-config.text

3 -rwx 110 info

4 -rwx 976 vlan.dat

6 -rwx 286 env_vars

26 -rwx 1592 config.text

8 drwx 1088 html

19 -rwx 110 info.ver

4393472 bytes available (3347968 bytes used)

switch:


!--- No IOS images or image directories exist in Flash.




If this is what your Flash directory looks like, proceed directly to Step 4 to recover the switch using an Xmodem file transfer.


If there is still an image in Flash, you may be able to recover the switch by issuing the boot command. To issue the boot command properly, you must first verify where the IOS image is stored in the Flash directory. This could be different depending on the model of switch you have.


Catalyst 2950/2955 Flash File System


The IOS image file (.bin file) always resides in the flash: directory on 2950 and 2955 series switches, as shown below.


switch: dir flash:

Directory of flash:/

3 -rwx 2888547 c2950-i6q4l2-mz.121-13.EA1.bin



!--- The IOS image file(.bin file) is stored in

!--- the flash: directory

!--- on 2950 and 2955 series switches.




4 -rwx 976 vlan.dat

6 drwx 832 html

22 -rwx 110 info

23 -rwx 110 info.ver

25 -rwx 38 env_vars


3132928 bytes available (4608512 bytes used)

Catalyst 3550 Flash File System


The Flash file system on a 3550 is organized a little differently. The IOS image file can be stored in the flash:directory, however, if you are using the Cluster Management Suite (CMS) image to manage switches with a web interface, the IOS Image file may be stored in its own directory. Issue the dir flash:directory command to display the image file in this case.


switch: dir flash:

Directory of flash:/

2 -rwx 976 vlan.dat

3 -rwx 386 system_env_vars

4 -rwx 5 private-config.text

6 -rwx 1554 config.text

24 drwx 192 c3550-i5q3l2-mz.121-13.EA1



!--- The IOS image file may be stored in a directory named

!--- with the image name excluding the .bin extension.


42 -rwx 33 env_vars


--- output suppressed ---


switch: dir flash:c3550-i5q3l2-mz.121-13.EA1



!--- Issue the dir flash:directory

!--- command to view the IOS image file.


Directory of flash:c3550-i5q3l2-mz.121-13.EA1/


25 drwx 832 html

40 -rwx 3993612 c3550-i5q3l2-mz.121-13.EA1.bin



!--- This is where the IOS image file is stored for a CMS image.



41 -rwx 252 info


9992192 bytes available (6006784 bytes used)

switch:

Attempting to Boot the Image


Once you have verified where the IOS image file resides, try to boot the image. Issue either the boot flash: filename or the boot flash: directory/filename command.


Catalyst 2950


switch: boot flash:c2950-i6q4l2-mz.121-13.EA1.bin




!--- The boot flash:filename

!--- command was used on a 2950.
