VLAN Trunking – Provides the ability to trunk different VLANs between multiple switches.
|
|
•
|
Layer 2 Network Discovery – Uses IEEE 802.1AB (LLDP) and Microsoft LLTD protocols and switch forwarding table to discover devices visible from a port.
|

•
|
Link Aggregation – Provides the ability to aggregate ports for increased performance and redundancy.
|
|
NOTE: On the NSA 2600, Link Aggregation for Network Interfaces is a separate feature from Link Aggregation for Switching. The NSA 2600 does support Link Aggregation for Network Interfaces (see Configuring Link Aggregation and Port Redundancy ), but the NSA 2600 does not support Switching and, therefore, does not support Link Aggregation for Switching.

Port Mirroring – Allows you to assign a mirror port to mirror ingress, egress or bidirectional packets coming from a group of ports.
|

•
|
Jumbo Frames – Supporting jumbo frames allows the SonicOS to process Ethernet frames with payloads ranging from 1500-9000 bytes.
|

|
Increased port density – With one appliance providing up to 26 interfaces, including up to 24 switch ports, you can decrease the number of devices on your internal network.

|
Increased security across multiple switch ports – The PortShield architecture provides the flexibility to configure all LAN switch ports into separate security zones such as LANs, WLANs and DMZs, providing protection not only from the WAN and DMZ, but also between devices inside the LAN. Effectively, each security zone has its own wire-speed “mini-switch” that benefits from the protection of a dedicated deep packet inspection firewall.

|
VLAN Trunking – Simplifies VLAN management and configuration by reducing the need to configure VLAN information on every switch; provides the ability to trunk different VLANs between multiple switches.
|
|
•
|
Layer 2 Network Discovery – Provides Layer 2 network information for all devices attached to the appliance; uses IEEE 802.1AB (LLDP) and Microsoft LLTD protocols and switch forwarding table to discover devices visible from a port.

•
|
Link Aggregation – Aggregated ports provide increased performance through load balancing when connected to a switch that supports aggregation, and provide redundancy when connected to a switch or server that supports aggregation.
|
|
•
|
Port Mirroring – Allows you to easily monitor and inspect network traffic on one or more ports and to assign a mirror port to mirror ingress, egress or bidirectional packets coming from a group of ports.
|
|
•
|
Jumbo Frames – Allows increased throughput and reduces the number of Ethernet frames to be processed by allowing SonicOS to process Ethernet frames with payloads ranging from 1500-9000 bytes. Throughput increase may not be seen in some cases. However, there will be some improvement in throughput if the packets traversing are really jumbo size.
