Upgrade 4506 switch to enable WCCP

pirrottina
Level 1
Level 1

Hi, we have a Cisco 4506 switch that is running IOS 12.2(20)EWA3. We are wanting to enable WCCP to use transparent proxying however I need to upgrade the IOS to support this feature. Going through the Software Advisor the latest it is telling me I can go to is 12.2(25). I guess I have several questions:

1) What version/build do I need to go to to enable WCCP? From what I can see it is at least 12.2(31)

2) Our version of IOS appears to be an ED version and to get above build 25 I need to move to an SG version or something like that. Is this correct?

3) The software advisor is telling me I don't have enough boot flash memory to perform the upgrade. Below is a copy of my show hardware and show file systems commands:

I don't see the amount of space you have in the file system, can you post the output from typing "dir /all" ?

Edit: BTW, all the IOS images old and new in the 4500 line are the same size and require the same memory. You need to make space for the new IOS image by deleting your current IOS image before copying the new one.

If you have more than 128MB in your flash, then you can have both IOS images at the same time but it's not necessary to have both.

Thanks

Thanks for your response. Below is the output of dir /all. It looks like there are two images on there already with the older one being used. And it appears the size of flash is 64MB.

Directory of bootflash:/

.bin

59244544 bytes total (34280976 bytes free)

There is more than enough room in bootflash to add another image , or if you want to you can get rid of the one you are not using by using the "delete bootflash:" command .

seeing the images are less than 13 meg and you have 34 meg free you have plenty of room .

Thanks for that. So how does this work? Do you configure the switch to boot off the new image, and if it fails then it can revert back to the old one, or is it a manual process to revert back?

Also, is 12.2(31) the version I should use to enable WCCP? Thanks

You configure the switch to boot off the new image with the boot system bootflash: command.

If you fail to supply this command, the IOS will select the first valid image from the file system.

It seems you have 2 images but one of the images is enclosed with "[]" which makes in an invalid file name on that search therefore it defaults to the second image in the list.

For WCCP, you need 12.2(31)SG as described in the Release Notes
