Network security can be increased by limiting access on a specific port only to users with specific MAC addresses. MAC addresses can be dynamically learned or statically configured. Locked port security monitors both received and learned packets that are received on specific ports. Access to the locked port is limited to users with specific MAC addresses. These addresses are either manually defined on the port, or learned on that port up to the point when it is locked. When a packet is received on a locked port, and the packet source MAC address is not tied
to that port (either it was learned on a different port, or it is unknown to the system), the protection mechanism is invoked, and can provide various options. Unauthorized packets arriving at a locked port are either:
Forwarded Discarded with no trap Discarded with a trap Cause the port to be shut down.
Trap Frequency The amount of time (in seconds) between traps. The default value is 10 seconds.
Security > Multiple Hosts

Port Mirroring Monitors and mirrors network traffic by forwarding copies of incoming and outgoing packets from one port to a monitoring port. Power over Ethernet (PoE) A technology enabling an Ethernet network cable to deliver both data and power. QoS (Quality of Service) Provides policies that contain sets of filters (rules). QoS allows network managers to decide how and what network traffic is forwarded according to priorities, application types, and source and destination addresses.

RADIUS (Remote Authentication Dial-In User Service) A protocol that uses an authentication server to control network access. RJ-45 (Registered Jack-45) An Ethernet connector that holds up to eight wires. RMON (Remote Monitoring) Provides network information to be collected from a single workstation. Router A networking device that connects multiple networks together. RSTP (Rapid Spanning Tree Protocol) Detects and uses network topologies that allow a faster convergence of the spanning tree, without creating forwarding loops. Server Any computer whose function in a network is to provide user access to files, printing, communications, and other services. SMTP (Simple Mail Transfer Protocol) The standard email protocol on the Internet. SNMP (Simple Network Management Protocol) A widely used network monitoring and control protocol. SSH Secure Shell. A utility that uses strong authentication and secure communications to log in to another computer over a network. SSL (Secure Socket Layer) Encryption technology for the Internet used to provide secure transactions, such as the transmission of credit card numbers for e-commerce. Static IP Address A fixed address assigned to a computer or device that is connected to a network. STP (Spanning Tree Protocol) Prevents loops in network traffic. The Spanning Tree Protocol (STP) provides tree topography for any arrangement of bridges. STP provides one path between end stations on a network, eliminating loops. Subnet (Sub-network) Subnets are portions of a network that share a common address component. In TCP/IP networks, devices that share a prefix are part of the same subnet. For example, all devices with a prefix of 157.100.100.100 are part of the same subnet. Subnet Mask An address code that determines the size of the network. Switch Filters and forwards packets between LAN segments. Switches support any packet protocol type. TACACS+ (Terminal Access Controller Access Control System Plus) Proprietary Cisco enhancement to Terminal Access Controller Access Control System (TACACS). Provides additional support for authentication, authorization, and accounting.
TCP (Transmission Control Protocol) A network protocol for transmitting data that requires acknowledgement from the recipient of data sent. TCP/IP (Transmission Control Protocol/Internet Protocol) A set of instructions PCs use to communicate over a network. Telnet A user command and TCP/IP protocol used for accessing remote PCs. TFTP (Trivial File Transfer Protocol) A version of the TCP/IP FTP protocol that has no directory or password capability. Throughput The amount of data moved successfully from one node to another in a given time period. Trunking Link Aggregation. Optimizes port usage by linking a group of ports together to form a single trunk (aggregated groups). TX Rate Transmission Rate. UDP (User Data Protocol) Communication protocol that transmits packets but does not guarantee their delivery. Upgrade To replace existing software or firmware with a newer version. Upload To transmit a file over a network. URL (Uniform Resource Locator) The address of a file located on the Internet. VLAN (Virtual Local Area Networks) Logical subgroups that constitute a Local Area Network (LAN). This is done in software rather than defining a hardware solution. WAN (Wide Area Network) Networks that cover a large geographical area. Wildcard Mask Specifies which IP address bits are used, and which bits are ignored. A wild card mask of 255.255.255.255 indicates that no bit is important. A wildcard of 0.0.0.0 indicates that all the bits are important. For example, if the destination IP address is 149.36.184.198 and the wildcard mask is 255.36.184.00, the first two bits of the IP address are used, while the last two bits are ignored.

Secure, reliable, intelligent, managed gigabit switching with PoE
The Linksys SRW2008P WebView fully managed switch brings gigabit speeds to your users, while adding a whole new level of intelligence and security to network. The eight 10/100/1000 Mbps ports enable you take advantage of the Gigabit Ethernet interfaces shipping on the current generation of servers, workstations and storage devices, in addition to supporting existing 10/100 Mbps clients. The optional miniGBIC ports allow you to expand network as your business grows. The SRW2008P supports the IEEE802.3af standard for Power over Ethernet (PoE). For applications where 4 or less PoE devices are being added, the SRW2008P is the ideal solution. It supports 4 ports at 15.4W per port (or 8 ports at 7.7W). All ports have automatic load sensing, where the power control circuitry automatically detects PoE on the enddevice before providing power; independent overload and short-circuit protection, along with LED indicators for power status.

SRW2008P

As more business functions and processes migrate to the network, having an intelligent network becomes a necessity. The SRW2008P is able to secure the network through IEEE 802.1Q VLANs, IEEE 802.1X port authentication, Access Control Lists (ACL) and MAC-based filtering. At the same time, the enhanced QoS and traffic management features ensure clear and reliable voice and video communications. Having this additional functionality is not useful if it cannot be implemented. Linksys WebView provides an intuitive, secure management interface enabling you to better utilize the comprehensive feature-set of the SRW2008P, resulting in a better optimized, more secure network.
