can be dynamically learned through GVRP or ports can be manually assigned to a specific set of VLANs. This allows the switch to restrict traffic to the VLAN groups to which a user has been assigned. By segmenting your network into VLANs, you can:
■Eliminate broadcast storms, which severely degrade performance in a flat network.
■Simplify network management for node changes and moves by remotely configuring VLAN membership for any port, rather than having to manually change the network connection.
■Provide data security by restricting all traffic to the originating VLAN, except where a connection has been configured between separate VLANs using a router or Layer 3 switch.
■Port Mirroring – The switch can unobtrusively mirror traffic from any port to a monitor port. You can then connect a protocol analyzer or RMON probe to this port to perform traffic analysis and verify connection integrity.
■Link aggregation – Ports can be combined into an aggregate link. Aggregate links can be manually set up or dynamically configured using IEEE 802.3ad Link Aggregation Control Protocol (LACP). The additional ports dramatically increase the throughput across any connection, and provide redundancy by taking over the load if a port in the trunk fails. The switch supports six aggregated links, with up to four
■Port Security – Port security prevents unauthorized users from accessing your network. It enables each port to learn, or be assigned, a list of MAC addresses for devices authorized to access the network through that port. Any packet received on the port must have a source address that appears in the authorized list, otherwise it will be dropped. Port security is disabled on all ports by default, but can be enabled on a
■Broadcast Suppression – Broadcast suppression prevents broadcast traffic from overwhelming the network. When enabled on a port, the level of broadcast traffic passing through the port is restricted. If broadcast traffic rises above a
■Flow Control – Flow control reduces traffic during periods of congestion and prevent packets from being dropped when port buffers overflow. The switch supports flow control based on the IEEE 802.3x standard. By default, flow control is disabled on all ports.
■Traffic Priority – This switch provides Quality of Service (QoS) by prioritizing each packet based on the required level of service, using four priority queues with Weighted Round Robin queuing. The switch uses IEEE 802.1p and 802.1Q tags to prioritize incoming traffic based on input from the
