I installed ICM 7.5 as sprawler in duplex mode. But router's mdsproc process always displaying message as "Synchronizer switching to non-duplex operation". But I can able to ping all the private ip address from both the ends.
This is the method to validate duplex behaviour.
1. Start LoggerA
2. Start RouterA.
Examine the trace in the router process window. It should say "synchronization hold off disabled".
3. Start RouterB and watch the router A window. When it handshakes to its peer, you should see router A start to download the config from logger A. If this does not happen, you have an error in the configuration.
Run ICMSetup.exe from the icm\bin directory. Carefully compare routerA and routerB. You have an error and you must find it.
