Enable Jumbo Frames only if devices across the network support them and are configured to use the same frame size. Due to tremendous amount of traffic occurring on an Ethernet port, it is likely that some frames greater than the standard Ethernet frame size are received. All devices are connected to the switch. This misconfiguration is clearly the cause of the Network Health Check MTU warning. This is a pretty useful feature and should generally be enabled. Enable jumbo frame support on switch (a Linksys business class in this case) Both of these are very straight forward and simple to do, but here is where it gets a little tricky. ProCurve Switch 2900 Series The ProCurve Switch 2900 series consists of two switches: the ProCurve Switch 2900-24G with 24 10/100/1000 ports and the ProCurve Switch 2900-48G with 48 10/100/1000 ports.
