As per this link 2811 routers support 256 MB CF. I know the P/N for 128 CF and it is MEM2800-128CF. What is the Cisco P/N for 256 MB CF? Is it MEM2800-256CF.

Is there a link on CCO giving this P/N MEM2800-256CF for our 2811 routers.

At the moment we are using 1 GB CF from a third party and we are having intermittent problem adding files to this CF after 80 MB only have been used out of 1 GB CF. We get "Failed Sector Write" error

Router#copy tftp flash:

Address or name of remote host []? Source filename []? c2800nm-spservicesk9-mz.124-15.T5.bin

Destination filename [c2800nm-spservicesk9-mz.124-15.T5.bin]?

Hi Alphonse,

I did a quick search in the price list and found that MEM2800-256CF= (256MB CF for the Cisco 2800 Series) part number is available for ordering.

However there is no document available on CCO.

I'll suggest, you get in touch with your partner/distributor and ask for a 256MB CF for your router.

these are the part numbers of CF cards available for 28xx series routers:

MEM2800-128CF= 128MB CF for the Cisco 2800 Series USD 700.00

MEM2800-256CF= 256MB CF for the Cisco 2800 Series USD 900.00

MEM2800-64CF= 64MB CF for the Cisco 2800 Series USD 400.00

You must stick to Cisco branded CFs only, anything else is not supported by Cisco.
