Support For The Smb 2.0 Protocol; Support For Cdp; Port-Based Load-Balancing Option For Multimode Interface Groups; Tso In Nics - IBM N Series Manual

It is a best practice to set the interface.blocked.mgmt_data_traffic option to
on, and to use the e0M interface only for management traffic. For more
information about the e0M interface, see the Data ONTAP 8.0 7-Mode System
Administration Guide and the Data ONTAP 8.0 7-Mode Software Setup Guide.

Support for the SMB 2.0 protocol

Data ONTAP 8.0.1 and later support the SMB 2.0 protocol, which is more
suitable than the original SMB protocol in environments requiring an
increased level of scalability and data integrity.
For more information, see the Data ONTAP 8.0 7-Mode File Access and Protocols
Management Guide.

Support for CDP

Cisco Discovery Protocol (CDP) is supported in Data ONTAP 7.3.3 and later
releases of the 7.x release family, and in Data ONTAP 8.0.1 and later. CDP
enables you to automatically discover and view information about directly
connected CDP-enabled devices in a network.
For more information about CDP, see the Data ONTAP 8.0 7-Mode Network
Management Guide.

Port-based load-balancing option for multimode interface groups

Port-based load balancing is supported for multimode interface groups in
Data ONTAP 7.3.2 and later releases of the 7.x release family, and in Data
ONTAP 8.0.1 and later. On a multimode interface group, you can uniformly
distribute outgoing traffic based on the transport layer (TCP or UDP) ports
and network layer addresses by using the port-based load-balancing method.
The port-based load-balancing method uses a fast hashing algorithm on the
source and destination IP addresses along with the transport layer (TCP or
UDP) port number.
For more information about port-based load balancing, see the Data ONTAP
8.0 7-Mode Network Management Guide

TSO in NICs

TCP segmentation offload (TSO) is a hardware feature supported on NICs to
increase the host CPU's efficiency.
Starting from Data ONTAP 8.0.1, the network interface cards that support
TSO are as follows:
v Dual 10G Ethernet Controller T320E-SFP+ and T320-XFP
v 10 Gigabit Ethernet Controller IX1-SFP+
