FEATURES |
- 2 Dual media ports for flexible fiber connection
Port 15 & 16 dual media ports are provided for flexible fiber connection. You can select to install optional SFP transceiver modules in these cages for short, medium, or long distance fiber backbone attachment. Use of the SFP will disable their corresponding build-in 10/100/1000Base-T connections.
- QoS Supports Layer 4 classification
The switch supports only only Layer 2 802.1p Priority Queue control, but also supports programmable higher layer classification and prioritization to enable enhanced Quality of Service (QoS) supports for real time application based on information taken from Layer 2 to Layer 4, such as VoIP.
- Port Mirroring helps supervisor monitoring network
Port mirroring copies traffic from a specific port to a target port. This mechanism helps track network errors or abnormal packet transmission without interrupting the flow of data.
- Q-in-Q VLAN for performance & security
The VLAN feature in the switch offers the benefits of both security and performance. VLAN is used to isolate traffic between different users and thus provides better security. Limiting the broadcast traffic to within the same VLAN broadcast domain also enhances performance. Q-in-Q, the use of double VLAN tags is an efficient method for enabling Subscriber Aggregation. This is very useful in the MAN.
- 802.3ad Port Trunk for bandwidth aggregation
The Gigabit ports can be combined together to create a multi-link load-sharing trunk. Up to 8 Gigabit ports can be set up per trunk for forwarding bandwidth up to 16Gbps, all traffic is aggregated based on MAC addresses, thus balancing the traffic load. The switch supports up to 8 trunking groups. Port trunks are useful for switch-to-switch cascading, providing very high full-duplex speeds.
- 802.1x Access Control improves network security
802.1x features enable user authentication for each network access attempt. Port security features allow you to limit the number of MAC addresses per port in order to control the number of stations for each port. Static MAC addresses can be defined for each port to ensure only registered machines are allowed to access. By enabling both of these features, you 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 mission critical environments with multiple switches supporting STP, you can configure the switches with a redundant backup bridge path, so transmission and reception of packets can be guaranteed in event of any switch on the network.
- Broadcast/Multicast storm control
To limit too many broadcast/multicast flooding in the network, broadcast/multicast storm control is used to restrict excess traffic. Threshold values are available to control the rate limit for each port. Packets are discarded if the count exceeds the configured upper threshold.
