Robert, Can you elaborate on what you mean by dropping? Are you losing connectivity from the client side? If so, what OS are you running? What type of switch are you plugging the Gigabit interface into from the Netapp end? What are the settings on the port on the switch? Mike

I am looking for some advice on one of the outputs from the ifstat command in ontap. when I run ifstat e4 (Gigabyte II card) I see the following

RECEIVE Packets: 36865k | Bytes: 12517m | Errors: 0 CRC: 0 | Bad length: 0 | Undersize: 0 Fragment: 0 | Oversize: 0 | Jabber: 0 FIFO overflow: 0 | NIC no buffer: 0 | Host no buffer: 65562 Queue overflow: 0 | Xon: 0 | Xoff: 0 Unknown flow ctl: 0 | Broadcast: 48933 | Multicast: 0 Jumbo: 0 TRANSMIT Packets: 49391k | Bytes: 50119m | Errors: 0 Oversize: 0 | Queue overflow: 0 | Timeout: 0 Broadcast: 3507 | Multicast: 7 | Jumbo: 0 LINK INFO Auto (learned): off | Media type: 1000sx-fd | Link state: up Flow control: full

The entry I am interested in is the Host no buffer: 65562. Is this a form of error?, should I be worried about it. The reason I ask is that from time to time our filer drops off the network altogher. Sometimes it comes back, sometimes it needs a power off and back on. We have tried installing a replacement netword card to no avail.

Any help or comments would be greatly appreciated..
