Hey Gang,

Just a FYI:

The MTU on the 3000 somewhat correlates to the NMMGR Network Segment Size parameter.

Path: NETXPORT.NI.LAN1
[1514 ] Network Segment Size (Bytes)

The value of 1514 is an internal buffer representation of the 1500 byte frames for ethernet or 802.3 plus some overhead bytes.

1514 is the default/recommended value for 10MB and 100BT networks... changes from this value may (YMWV) result in less than optimal performance for these link types.

If your switch/router vendor says to decrease this value to work with their equipment, they probably have a bug they are working around.

I hope this helps.


Regards,

James Hofmeister
