Differentiated Services (DiffServ)

With DiffServ, the switch marks packets so that they receive specific per-hop treatment at DiffServ-compliant network devices along the route based on the application types and traffic flow.

Classifier

You can configure a classifier to categorize traffic flow and then define actions to be performed on a traffic flow grouped by a classifier according to specific criteria such as the IP address, port number or protocol type, etc..

Queuing

Queuing is used to help solve performance degradation when there is network congestion. Two scheduling services are supported: Strict Priority Queuing (SPQ) and Weighted Fair Queuing (WFQ). This allows the switch to maintain separate queues for packets from each individual source or flow and prevent a source from monopolizing the bandwidth.

Port Mirroring

Port mirroring allows you to copy traffic going from one or all ports to another or all ports in order that you can examine the traffic from the mirror port (the port you copy the traffic to) without interference.

Static Route

Static routes tell the switch how to forward IP traffic when you configure the TCP/IP parameters manually.

IGMP

IGMP (Internet Group Multicast Protocol) is a session-layer protocol used to establish membership in a multicast group - it is not used to carry user data.

IGMP Snooping

The switch supports IGMP snooping enabling group multicast traffic to be only forwarded to ports that are members of that group; thus allowing you to significantly reduce multicast traffic passing through your switch.

IP Multicast

With IP multicast, the switch delivers IP packets to a group of hosts on the network - not everybody. In addition, the switch can send packets to Ethernet devices that are not VLAN- aware by untagging (removing the VLAN tags) IP multicast packets.
