We until recently had two x Netgear Managed Switches. One kept locking up intermitently, so we decided to replace it and bought the Cisco ESW500.
The two managed switches can link together ok, but we have another issue now.
Some of our users connect to the switches via Netgear FS108 Desktop Switches and other connect in direct. The direct users can connect to the Cisco fine, any 'hubbed' users cannot connect into the cisco and instead have to connect to the Netgear.
If only one user connected via a 'hub' it is ok ... but not multiple users.
Not a huge issue at this stage, but once we run out of space in the netgear it will be.
