I have had an ongoing issue with SDM 2.5 not working correctly with an 877 ISR since the IOS was upgraded to 12.4(22)T. Prior to this it worked fine, however since 12.4(22)T HTTPS access has not worked correctly:
My workaround was to use HTTP instead of HTTPS. Since a few days ago though SDM has stopped working altogether, it seems as a result of the Java client upgrading itself.
Since SDM is being replaced with CCP I decided to install this and see if this works as I doubt SDM is still being developed? CCP Versions 1.1 & 1.2 don't work with the 877 (most pages don't display) but the latest 1.3 Beta almost works fully. The only pages I can't access are the IPS ones. I have verified I have the -Xmx256m switch in the Java runtime settings but still the pages fail to display.
I know this is a Beta but there is nothing in the release notes about the IPS pages not working. I have an 877 running 12.4(24)T Advanced IP Services.
