QoS with 4 Priority Queues
The QoS (Quality of Service) feature provides 8 internal queues to support 2 different classifications of traffic. High priority packet streams will experience less delay inside the switch, which provides a lower latency level for certain delay-sensitive traffic. It can classify the packet as one of the 2 priorities according to 802.1p priority tag and DSCP. The QoS operates at full wire speed, and the actual scheduling at each egress port can be based upon a strict weighted round robin.
The port mirroring feature allows the ingress traffic to execute port copying. This mechanism helps track network errors or abnormal packet transmission without interrupting the flow of data, allowing ingress traffic to be monitored by a single port that is defined as a mirror capture port. The mirror capture port can be any port. Mirroring multiple ports is possible, but can create congestion at the mirror capture port.
Q-in-Q VLAN for Improved Performance & Security
The VLAN feature in the switch offers the benefit of improved security and performance. VLAN is used to isolate traffic between different users, thus providing better security. Limiting the broadcast traffic within the same VLAN broadcast domain also enhances performance. Q-in-Q, the use of double VLAN tags, is an efficient method to enable subscriber aggregation.
Isolated Group for Port Protection
The isolated group feature allows certain ports to be designated as protected ports. All other ports are non-isolated. Traffic between isolated group members are blocked. Traffic can only be sent from the isolated group to the non-isolated group.
802.1x Port-Based Network Access Control for Improved Network Security
The 802.1x feature enables user authentication for every network access attempt. The port security feature allows users to limit network access to non-registered users. By enabling these features, users can establish an access mechanism based on user and machine identities, as well as control the number of access stations.
802.1d Compatible & 802.1w Rapid Spanning Tree
For environments with multiple switches supporting STP, users can configure the switches with a backup bridge path, so transmission and reception of packets can be guaranteed in the event of a switch fail-over.
Broadcast/Multicast/Unknown-Unicast Storm Control
To prevent broadcast, multicast, or unknown-unicast flooding in the network, the storm control function can be used to restrict excess traffic. Threshold values are available to control the limit rate for each port. Packets will be discarded if the count exceeds the designated upper threshold.
