Built-in Unique PoE Functions for Powered Devices Management
As a managed PoE switch for surveillance, wireless and VoIP networks, the LRP-422CST particularly features the following special PoE Management functions to accomplish a highly-efficient Long Reach network:

■ PD Alive Check
■ Scheduled Power Recycling
■ PoE Schedule
■ PoE Usage Monitoring

Intelligent Powered Device Alive Check
The LRP-422CST can be configured to monitor connected PD (Powered Device) status in real time via ping action. Once the PD stops working and responding, the LRP-422CST will resume the PoE port power and bring the PD back to work. It will greatly enhance the network reliability through the PoE port resetting the PD’s power source and reducing administrator management burden.

Scheduled Power Recycling
The LRP-422CST allows each of the connected PoE IP cameras or PoE wireless access points via the LRP-101CE Long Reach PoE Extender to reboot at a specific time each week. Therefore, it will reduce the chance of IP camera or wireless AP crash resulting from buffer overflow.

PoE Schedule for Energy Saving
Under the trend of energy saving worldwide and contributing to environmental protection, the LRP-422CST can effectively control the power supply besides its capability of giving high watts power. The “PoE schedule” function helps you to enable or disable PoE power feeding for each PoE port during specified time intervals and it is a powerful function to help SMBs or enterprises save power and budget. It also increases security by powering off PDs that should not be in use during non-business hours.

PoE Usage Monitoring
Via the power usage chart in the web management interface, the LRP-422CST enables the administrator to monitor the status of the power usage of the connected PDs in real time. Thus, it greatly enhances the management efficiency of the facilities.

IPv6/IPv4 Dual Stack
Supporting both IPv6 and IPv4 protocols, the LRP-422CST helps the SMBs to step in the IPv6 era with the lowest investment as its network facilities need not be replaced or overhauled if the IPv6 FTTx edge network is set up.

Robust Layer 2 Features
The LRP-422CST can be programmed for advanced switch management functions such as dynamic port link aggregation, 802.1Q VLAN and Q-in-Q VLAN, Multiple Spanning Tree Protocol (MSTP), Loop and BPDU Guard, IGMP Snooping, and MLD Snooping. Via the link aggregation, the LRP-422CST allows the operation of a high-speed trunk to combine with multiple ports such as an 8Gbps fat pipe, and supports fail-over as well. Also, the Link Layer Discovery Protocol (LLDP) is the Layer 2 Protocol included to help discover basic information about neighboring devices on the local broadcast domain.

Efficient Traffic Control
The LRP-422CST is loaded with robust QoS features and powerful traffic management to enhance services to business-class data, voice, and video solutions. The functionality includes broadcast/multicast storm control, per port bandwidth control, IP DSCP QoS priority and remarking.

Powerful Security
PLANET LRP-422CST offers comprehensive IPv4/IPv6 Layer 2 to Layer 4 Access Control List (ACL) for enforcing security to the edge. It can be used to restrict network access by denying packets based on source and destination IP address, TCP/UDP ports or defined typical network applications. Its protection mechanism also comprises 802.1X port-based user and device authentication, which can be deployed with RADIUS to ensure the port level security and block illegal users. With the Protected Port function, communication between edge ports can be prevented to guarantee user privacy. Furthermore, Port Security function allows to limit the number of network devices on a given port.

Advanced Network Security
The LRP-422CST also provides DHCP Snooping, IP Source Guard and Dynamic ARP Inspection functions to prevent IP snooping from attack and discard ARP packets with invalid MAC address. The network administrators can now build highly-secure corporate networks with considerably less time and effort than before.
