Our client is a hotel with about 600 guest rooms. We configured the switches having 1 vlan per room and our management vlan is vlan 1000. We also configured spanning-tree instances due to so many vlans. We have a total of 35 switches for their network infrastructure which includes 2 units of Cisco 3750 stacked and the rest are Cisco 2960 switches deployed as either distribution and access layer. Configuration-wise everything is just fine but on Ciscoworks LMS, there are instances that it shows in the topology map that a particular switch is down but in reality the users connected to it is having no problems. This occurs randomly, in no particular switch at no specific time. The down switches though comes up after some time. The Ciscoworks LMS 2.6 server is connected directly to the core switch as member of vlan 1000.
Need help on this matter so that monitoring of the switches would be reliable.
