You should see under the Menu -->

 Advanced Settings -->

MaxLog Entries

Jumbo Frames

With Current & After Reset............are you not seeing these options ?

The only place I found is:

<>Switching -->

<> Ports -->

<> Port Configuration -->

<> and you could specify Maximum Frame Size <>

Thanks mandzo, I didn't find it.

the 62xx switch support different framesize per port.  So the configuration is on the port configuration page.

The 5324 switch supports jumbo frame configuration at the switch level only, not per port.
