• Simplify network management for node changes/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.
Port Mirroring – The switch can unobtrusively mirror traffic from any
port to a monitor port. You can then attach a protocol analyzer or RMON
probe to this port to perform traffic analysis and verify connection
integrity.
Port Trunking – Ports can be combined into an aggregate connection.
Trunks 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 should fail. The
switch supports four trunks, with up to eight up-link ports per trunk.
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 pre-defined threshold, it will be throttled until the level
falls back beneath the threshold.
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 enabled on all ports.
Traffic Priority – This switch provides Quality of Service (QoS) by
prioritizing each packet based on the required level of service, using two
priority queues, and processing the high-priority queue before the low-
priority queue, or using Weighted Round Robin Queuing (WRR). It uses
IEEE 802.1p and 802.1Q tags to prioritize incoming traffic based on input
from the end-station application. These functions can be used to provide
independent priorities for delay-sensitive data and best-effort data.
