How do I know if I'm running modular IOS?

Hi,

Is there anywhere in the show version command that would indicate if a device is running the default or modular version of the IOS?

The IOS filename will have vz if modular and mz if regular IOS.

For instance:

Modular

s72033-ipservicesk9_wan-vz.122-33.SXH3a.bin

Regular

s72033-ipservicesk9_wan-mz.122-33.SXH3a.bin

Re: How do I know if I'm running modular IOS?

Hi,

It is possible to be running an image with vz in the name yet not be modular. The process to run modular is (briefly)

copy image to device

boot from that image

"install" the image

reload to installed version

The output of "show ver" when running the installed version will include:

System is currently running from installed software

For further information use "show install running"

If it's not "installed" it is not upgradeable with individual modules. I'd give you the link to installing modular IOS but I can't find it. :-)
