HP2524 + GigaBit Ethernet SX and MTU Size

Hello there,

Question, is this Possible on a HP2524 (J4813A) with a HP ProCurve Gigabit SX Transceiver (J4131B) and Firmware 5.22 to set the MTU Size on the Gigabit SX Module to 2000 ?

I gote always Error like this in the Eventlog
port 25-Excessive jabbering. See Help

If i look on Port 25 i see some Giant Errors always

Interface 25 is running in a Trunk Mode

Status and Counters - Port Counters for port 25

On the Port 25 i have a Cisco Switch connectett with a MTU Size of 2000 for L2TP Tunneling on ADSL Service, now i need also MTU Size 2000 on the HP Switch.

Thanks for any Help or Solutions

I think only the 2800 and 9300 series will do jumbo frames. The 2524 is too old.
