Linksys SRW224G4P

Linksys SRW224G4P , 24-Port Managed Gigabit Switch with WebView and PoE .
24-Port Managed Gigabit Switch with WebView and PoE ,(24) 10/100 ports + (2) shared Gigabit combo ports + (2) Gigabit uplink ports

The Linksys WebView Managed switch allows you to expand your network securely. Configuration of the switch is secured using SSL for Web access. User control is secured using 802.1x security using a RADIUS authentication mechanism and can also be controlled using MAC filtering. Extensive QoS features makes the solution ideal for real-time applications like Voice and Video. The 4 priority queues together with the Weighted Round Robin and Strict Priority scheduling techniques facilitate efficient co-existence of real-time traffic with data traffic allowing them each to meet their QoS needs. Individual users or applications can be prioritized above others using various Class of Service options - by port, layer 2 priority (802.1p), and Layer 3 priority (TOS or DSCP). Intelligent Broadcast, and Multicast storm control minimizes and contain the effect of these types of traffic on regular traffic. IGMP Snooping limits bandwidth-intensive video traffic to only the requestors without flooding to all users. Incoming traffic can be policed and outgoing traffic can be shaped allowing you to control network access and traffic flow.

There are features that allow you to expand and grow your network of switches. Link aggregation allow multiple high-bandwidth trunks between switches to be setup. This also provides a level of reliability in that the system continues to operate if one of the links break. Spanning Tree (STP), Fast Spanning Tree, and Rapid Spanning Tree (RSTP) allow you to build a mesh of switches increasing the availability of the system.

The rich management functionality of the WebView switches includes SNMP, RMON, Telnet, and HTTP Management options, allowing you to flexibly integrate and manage these devices in your network.

Automatic Load Sensing - Power control circuitry automatically detects Power over Ethernet on access point before providing power. Power feeding of Ethernet limited for fixed 10/100 Base-T/TX ports. The solution can provide maximum output power per PoE port up to 15.4W on 24 ports simultaneously. Independent overload and short-circuit protection for each port. LED indicators for power status per PoE port. Support IEEE802.3af MIB for power over Ethernet function. Support IEEE 802.1d spanning tree, IEEE 802.1w Rapid STP, Fast Linkover, IEEE 802.1s Multiple STP. Cable diagnostics.
