Are Jumbo frames supported on the ProCurve 6200yl series switches?
Yes. Ports operating at 1 Gbps or 10 Gbps speeds accept forward packets of up to 9220 bytes (including four bytes for a VLAN tag) when configured for jumbo traffic. Note that on ports operating at 10 Mbps or 100 Mbps, the Maximum Transmission Unit (MTU) is fixed at 1522 bytes. The switch drops any inbound packets larger than the MTU allowed on a port.
