Linksys srw248g4p Техническое Руководство

The Linksys Switch with WebView allows you to expand your network securely. 

Configuration of the switch is secured using SSL for Web access. User control is 

secured with 802.1X security using a RADIUS authentication mechanism and can also 

be controlled using MAC-based 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 coexistence 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 

controls minimize 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 

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 allows 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,  Rapid Spanning Tree (RSTP), and Multiple Spanning 

Tree (MSTP) 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.

Power control circuitry (Automatic load sensing) automatically detects Power over Ethernet on 

access points before providing power. Power feeding of Ethernet is limited for fixed 10BASE-T/

100BASE-TX ports. The solution can provide maximum output power per PoE port up to 15.4W on 

24 ports simultaneously. The Switch provides independent overload and short-circuit protection 

for each port, LED indicators for power status per PoE port, and supports IEEE802.3af MIB for Power 

over Ethernet functionality. The Switch supports IEEE 802.1d spanning tree, IEEE 802.1w Rapid STP, 

Fast Linkover, and IEEE 802.1s Multiple STP. Cable diagnostics can be performed using the Switch’s 

WebView utility.
