Jumbo frames on HP ProCurve 1810G - 24 GE, P.1.17, eCos-2.0

HI all,

I'm trying to use jumbo frames over a HP ProCurve 1820G - 24 GE switch:

System Description

HP ProCurve 1810G - 24 GE, P.1.17, eCos-2.0 System Name System Location System Contact Software Version P.1.17 System Object ID 1.3.6.1.4.1.11.2.3.7.11.104 System Up Time 0 days, 1 hours, 26 mins, 24 secs Current Time 17:26:24 ( hh:mm:ss ) Date 12/31/1969

Switching -> Enable Jumbo Frames is set, Status ->Port Summary shows 9216 bytes MTU for all ports.

I have tried to "ping -s 4000" on linux or "ping -l 4000" on windows between 4 machines. All had the interface's MTU set to 8192 or higher. I didnot receive a single ICMP reply.

Is there a bug in the switches' firmware?

Also, please note how it is an 1820 switch, but the firmware says its 1810. Is that a problem?

Thanks!
