How can I check file names of IOS and asdm loaded to FWSM? If I load new version of IOS, how can I erase the old one? Is it rewrited automaticly?
Command "dir flash" shows only that they presented on the flash.
Directory of flash:/
2 -rw- 3394960 <no date> asdm
1 -rw- 6062080 <no date> image
You cannot. The flash can only take one image and one asdm unlike the PIX/ASA. When you issue
copy tftp flash:image
copy tftp flash:adsm
Both of them will get replaced. Upon reload
sh ver should tell you the image and the asdm version loaded.
Image upgrade/downgrade required a reload
asdm upgrade/downgrade does not require a reload.
