Queuing
Queuing is used to help solve performance degradation when there is network congestion. Three scheduling services are supported: Strict Priority Queuing (SPQ), Weighted Round Robin (WRR) and Weighted Fair Schedule (WFS). 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 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.
Multicast VLAN Registration (MVR)
Multicast VLAN Registration (MVR) is designed for applications (such as
This improves bandwidth utilization by reducing multicast traffic in the subscriber VLANs and simplifies multicast group management.
STP (Spanning Tree Protocol) / RSTP (Rapid STP)
(R)STP detects and breaks network loops and provides backup links between switches, bridges or routers. It allows a switch to interact with other (R)STP
The switch allows you to create multiple STP configurations and assign ports to a specific tree.
Link Aggregation
Link aggregation (trunking) is the grouping of physical ports into one logical
