Versatile Interface Processor Functions

Follow these steps to download (copy) a microcode version from a TFTP server to Flash memory.

Step 1 To display the total amount of Flash memory present, its location, any ﬁles that currently exist in Flash memory and their size, and the amount of Flash memory remaining, use the show ﬂash command. Following is an example of the output that is displayed:


-#- ED --type-- --		crc--- -	seek--	nlen	-length-	-----	date/time------		name
1	.. FFFFFFFF B4A18E0B 3F6494			30	4023316	Jun	26 1994	19:44:29	image/file/1
2	.. FFFFFFFF 8075AA5D 4118B4			23	111518	Jun	29 1994	11:05:57	image/file/2

12044568 bytes available (8533736 bytes used)

Step 2 Compare the amount of available Flash memory (last line in the preceding example) to the size of the new microcode image on the ﬂoppy disk. If you attempt to copy in a new image, and the size of the new image exceeds the available space in Flash, only part of the new image will be copied, and the following error message will be displayed:

buffer overflow - xxxx/xxxx

where xxxx/xxxx is the number of bytes read in/number of bytes available.

Step 3 After you verify that there is sufﬁcient space available in Flash memory for the new image, use the command copy tftp:ﬁlename [ ﬂash slot0 slot1 ]:ﬁlename to copy an image to Flash memory. (tftp:ﬁlename is the ﬁle’s source, and [ ﬂash slot0 slot1 ]:ﬁlename is the destination in onboard Flash memory or on either of the Flash memory cards.)

An example of the copy tftp:ﬁlename command follows:

Router# copy tftp:vip11-1 slot0:vip11-1

20575008 bytes available on device slot0, proceed? [confirm] Address or name of remote host [1.1.1.1]?

Step 4 Use the show ﬂash command to verify that the microcode has been copied to Flash. The output should display the ﬁlename of the image you copied to Flash ( vip11-1in the following example):
