DIGISOL launches managed fast Ethernet layer 2 switch

MUMBAI, INDIA: DIGISOL has introduced its high performance Layer 2 Managed Switch DG-FS4526 for workgroup environment.

This switch brings high level of availability, enhanced security and advanced QoS to the network edge, while maintaining simplicity of management at an affordable price. It comes with 8.8 Gbps switching capacity, 24 10/100 ports and 2 Combo Gigabit Ethernet RJ-45/SFP ports. DIGISOL SFP transceivers can be used with the Combo Ports for choice of Multimode or Single Mode Gigabit Uplink or server connectivity.

You can control a virtual stack of up to 36 switches as a single entity using IP Clustering with a single IP address. The Web-based user port authentication allows easy deployment of User Access Control using a simple browser interface. With 8.8 Gbps switching capacity, DG-FS4526 delivers wire-speed switching performance, allowing users to take full advantage of existing high performance, gigabit integrated Servers, PCs and Laptops.

Four Egress Queues per port enable differentiated management of up to four traffic types. Traffic is prioritized according to 802.1p, DSCP, IP precedence and TCP/UDP port number, giving optimal performance to real-time applications such as Voice and Video. Asymmetric bidirectional rate-limiting preserves network bandwidth allowing maximum control of network resources.

IEEE 802.1w Rapid Spanning Tree Protocol provides a loop-free network and redundant links to the core network with rapid convergence, to ensure faster recovery from failed links, enhancing overall network stability and reliability. IEEE 802.1s Multiple Spanning Tree Protocol, IEEE 802.3ad Link Aggregation Control Protocol, IGMP snooping and Broadcast Storm Control are some of the other features used to enhance bandwidth, load sharing/balancing, fault tolerance and to prevents flooding of IP multicast traffic.

IEEE 802.1x port-based access control ensures all users are authorized before being granted access to the network. User authentication is carried out using any standard-based RADIUS server. Port Security ensures access to switch ports based on MAC address limits the total number of devices from using a switch port and protects against MAC flooding attacks.

Access Control Lists (ACLs) can be used to restrict access to sensitive network resources. Secure network management is provided using Security Shell (SSH) and Secure Sockets Layer (SSL/HTTPS).
