Solved: ASDM certificate warning

Beat.Traber · ‎11-07-2013

Hi

I manage a couple of FWSMs and ASAs using ASDM.

Recently I get warnings on some of these devices (but only on some).

The warnings say, that the certificate is not valid and that in a future Java-release ASDM will be blocked for this reason (because of some missing attribute in the JAR file).

I have 2 FWSM one of which brings this warning whereas the other one doesn't. Both use the same versions:

FWSM Firewall Version 4.1(6) <context>

Device Manager Version 6.2(2)F

How do I proceed? I'm not at all keen losing ASDM-connectivity...

Thanks for any suggestions.
