We recently upgraded almost all of our 5520/5510 switches to 4826/4850's. Since we did this we have had problems with COM and discoveries. When we do discoveries we can either manage all switches or have 3-15 that are not manageable (orange). If we do another discovery the previous orange ones are now blue and different switches come up orange.
I tried to change the SNMP timeout and we haven't lost quite as many at any one time but still lose some on a few discoveries. Any ideas on what else we could change that we can manage all of our switches.
We have also had it happen where you are in a switch in COM making changes and then it will stop responding. If you do a discovery then it will show up "orange", until we do another discovery.
We are using FW:5.8.0.1 SW:v5.8.3.017 BN:17.
