Page 10: Introduction
User’s Manual of LRP-822CS 1. INTRODUCTION Thank you for purchasing PLANET 8-port Coax + 2-port 10/100/1000T + 2-port 100/1000X SFP Long Reach PoE over Coaxial LRP Managed Switch, LRP-822CS. “LRP Managed Switch” mentioned in this Guide refers to the LRP-822CS.
Page 11: Product Description
Gigabit copper ports and 2 extra 100/1000BASE-X SFP fiber slots. Each of the eight BNC ports provides 36 watts of power with a total power budget of up to 240 watts. As an advanced PoE switch, the LRP-822CS features intelligent PoE functions to improve the availability of critical applications.
Page 12 It gives users the flexibility to expand small area network with BNC T-connector for sharing four nodes per port when needed, making the LRP-822CS with 8 BNC Long Reach PoE Ports an ideal support for up to 32 IP cameras.
Page 13 The LRP-822CS 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-822CS 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...
Page 14 IPv6 / IPv4 Dual Stack Supporting both IPv6 and IPv4 protocols, the LRP-822CS 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.
Page 15 Powerful Security PLANET LRP-822CS 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.

EEE works by powering down circuits when there is no traffic. When a port gets data to be transmitted all circuits are powered up. The time it takes to power up the circuits is named wakeup time.

User’s Manual of LRP-822CS 4.4 Link Aggregation Port Aggregation optimizes port usage by linking a group of ports together to form a single Link Aggregated Groups (LAGs). Port Aggregation multiplies the bandwidth between the devices, increases port flexibility, and provides link redundancy.
Page 100 User’s Manual of LRP-822CS The Link Aggregation Control Protocol (LACP) provides a standardized means for exchanging information between Partner Systems that require high-speed redundant links. Link aggregation lets you group up to eight consecutive ports into a single dedicated connection. This feature can expand bandwidth to a device on the network. LACP operation requires full-duplex mode.

VLAN allow a network to be segmented in order to reduce the size of broadcast domains. All packets entering a VLAN will only be forwarded to the stations (over IEEE 802.1Q enabled switches) that are members of that VLAN, and this includes broadcast,...

Page 114: Management Vlan
User’s Manual of LRP-822CS ■ Assigning Ports to VLANs Before enabling VLANs for the switch, you must first assign each port to the VLAN group(s) in which it will participate. By default all ports are assigned to VLAN 1 as untagged ports. Add a port as a tagged port if you want it to carry traffic for one or more VLANs, and any intermediate network devices or the host at the other end of the connection supports VLANs.

Page 138: Spanning Tree Protocol
User’s Manual of LRP-822CS 4.6 Spanning Tree Protocol 4.6.1 Theory The Spanning Tree Protocol can be used to detect and disable network loops, and to provide backup links between switches, bridges or routers. This allows the switch to interact with other bridging devices in your network to ensure that only one route exists between any two stations on the network, and provide backup links which automatically take over when a primary link goes down.
Page 139 User’s Manual of LRP-822CS  The path cost to the root from the transmitting port  The port identifier of the transmitting port The switch sends BPDUs to communicate and construct the spanning-tree topology. All switches connected to the LAN on which the packet is transmitted will receive the BPDU.

User’s Manual of LRP-822CS 4.9.1.1 Understanding IEEE 802.1X Port-based Authentication The IEEE 802.1X standard defines a client-server-based access control and authentication protocol that restricts unauthorized clients from connecting to a LAN through publicly accessible ports. The authentication server authenticates each client connected to a switch port before making available any services offered by the switch or the LAN.
Page 213 User’s Manual of LRP-822CS  Authentication server—performs the actual authentication of the client. The authentication server validates the identity of the client and notifies the switch whether or not the client is authorized to access the LAN and switch services.
Page 214 User’s Manual of LRP-822CS Figure 4-9-2 EAP Message Exchange Ports in Authorized and Unauthorized States  The switch port state determines whether or not the client is granted access to the network. The port starts in the unauthorized state. While in this state, the port disallows all ingress and egress traffic except for 802.1X protocol packets. When a client is successfully authenticated, the port transitions to the authorized state, allowing all traffic for the client to flow normally.
