problem with common services discovery !

hi, I have set the network discovery setting to use (arp-ospf, and cdp) . after the network discovery was finished I found out that there are 30 devices which had been discovered but in unreachable state !!!!

I start to ping all those devices and hopfully all of them had good reply times, I wonder how is it posible that a device go to unreachable state as long as I have its ping reply ??

thank you indeed

Discovery does more than simply ping devices.  In order for a device to be reachable, Discovery must be able to communicate with the device via SNMP.  Take a look at this document for more on how Discovery works:
