Stacking for Scalability and High Availability

The new Generation of Stackable Smart Switches use 2 dedicated ports in the front of the switch for stacking, providing a 10Gbps, dual-ring, highly redundant stacking bus that carries intra-stack traffic and provide highest level of resilience, allowing you to stack up to six switches or up to 300 10/100/1000 Mbps ports, forming a virtual chassis for easy management under a single IP address. This stacking technology also provides several high-availability features to ensure business continuity:

Resiliency: Due to redundant stacking port connections, there is an automatic fail-over in case any switch in the stack fails, with rapid reconfiguration, thus preventing network downtime.
Hot-swappable: All switches in the stack are hot-swappable, and can be integrated or removed without disrupting the network.
All switches in the stack are hot-swappable, and can be integrated or removed without disrupting the network

These Stackable Smart Switches come with a complete suite of advanced features for more robust security, higher quality of service and high availability. This switch is equipped with highly advanced features such as access control lists (ACL), static routing, rate limiting, IGMP snooping, and Dynamic VLAN assignment among others to provide a small and medium sized business with a network that is geared for growth while providing scalability and reliability.

Advanced Security
These switches also provide advanced features that provide more robust security to SMBs.

These include:
802.1x for authentication
ACL filtering to permit or deny traffic based on MAC and/or IP addresses
Advanced Quality of Service (QoS)

Priority queuing ensures high-priority traffic gets delivered efficiently, even during congestion from high traffic bursts. Companies implementing network telephony or video conferencing, for example, need to be able to prioritize such voice and video traffic and other real-time applications over less latency-sensitive traffic to ensure reliability and quality. The ability to prioritize traffic ensures quality of latency-sensitive services and applications despite increasing traffic loads.

Friendly to converged network with voice and video, the Stackable Smart Switches offers Auto Voice and Auto Video features that automatically configures QoS, Security and VLAN settings for IP phones and IP cameras.

IPv6 Support
IGMP filtering and querier ensure multicast streams are only delivered to interested receivers, preventing flooding even without a dedicated multicast router. When receivers are in different VLANs, Multicast VLAN registration (MVR) uses a dedicated multicast VLAN to forward multicast streams and avoid duplication for clients in different VLANs.
