hi

Try compress the configs in flash...service compress-config to free up space  , what space is left when your run ...dir nvram:

can anything be deleted from nvram ?

after its compressed try again , if not then you need to delete something

Hi,

thanks for your support, but when i put service compress-config on switch that time we get below error

Error- (config)#service compress-config
Boot ROMs do not support NVRAM compression.
Disabling service compress-config.

And when we put

CISCO1#dir nvram:

that time we get below mentioned output

CISCO1#dir nvram:
Directory of nvram:/

%Error opening nvram:/ (Function not implemented)

524288 bytes total (483211 bytes free)

plz tell in this case what we do....

Regards

ok try this post

show boot

check the buffer size and change it and then reload the switch

(conf t)boot buffersize (number for nvram size)

then run again--- dir nvram:

looks like nvram has become corrupted , hopefully its not hardware at fault

Hi Mark,

thanks for your quick reply

but can you tell me what buffersize  I configure on switch

Regards

Sudhir

[Mark Malone]

Found this thread, but I couldn't really reboot the device (who knows how long it hasn't been saving the config), so I just ran:

erase startup-config

then

write memory

and it seemed to fix it without needing to modify the buffer size or reboot it.
Here's the log.
