hello, I am having trouble installing any version of the SDM on a 1711 router running [C1700-ADVSECURITYK9-M Version 12.4(2)T]. I have tried several code versions with no success. The error message I receive when the installation fails is "This router model is not supported by SDM. Please enter the IP address of a router supported by SDM". All the documentation I find from Cisco says that this device supports SDM. Release Notes for SDM says the same thing.
