Cisco ASA: Upgrade ASDM image the manly way
I’ll be honest. I came from an all Fortigate shop, and the last real hardcore Cisco work I did was on a PIX.
Since it’s been like six years, I figured I’d doc the very simple procedure to upgrade the ASDM image on an ASA.
A highly intelligent folk who quality checked a refurbed ASA 5505 before shipping as a warranty replacement thought… “hey, I’ll upgrade the IOS, but not upgrade the ASDM.” Since I’m hardcore and don’t bother with the ASDM, only CLI, I didn’t worry about it before certifying a config as good before release. Well, god dang it, we need the ASDM! Alas, I found an awesome troubleshooting page on Cisco’s site, and realized that I may have to upgrade the ASDM image. So, here’s how.
1) Get your version information with the following:
sh ver #Cisco Adaptive Security Appliance Software Version 8.2(5)55 #Device Manager Version 5.2(3) <=== this is not listed as compatible
2) Take a gander at the ASA/ASDM compatibility matrix.
The ASA version I'm running is listed as being compatible with "ASDM 6.3(4) and later. Recommended: 7.4(2)."
3) download the image by searching this annoying site (just use IE, trust me)
3) grab a tftp server app and copy the .bin to the served directory (try tftpd64)
4) copy the image up to the flash
copy tftp flash #server is: 10.8.6.145 #source & destination filename is: asdm-742.bin
5) verify the presence of the image
show disk #.... asdm-742.bin
6) show the existing asdm image
sh run asdm #asdm image disk0:/asdm-523.bin
6) assign the new image:
asdm image disk0:/asdm-742.bin wr mem
