Status Displays the connection status between the device and the TACACS+ server. The possible field values are:
Providing various mechanisms for determining the allocation of network resources to different handling classes, including:
The assignment of network traffic to a particular
The assignment of internal resources Traffic shaping
The terms Class of Service (CoS) and QoS are used in the following context: CoS provides varying Layer 2 traffic services. CoS refers to classification of traffic to traffic-classes, which are handled as an aggregate whole, with no per-flow settings. CoS is usually related to the 802.1p service that classifies flows according to their Layer 2 priority, as set in the VLAN header. QoS refers to Layer 2 traffic and above. QoS handles perflow settings, even within a single traffic class.
QoS > CoS Settings
Broadcast Control Indicates whether broadcast packet types are forwarded on the specific interface. Mode Specifies the Broadcast mode currently enabled on the device. The possible field values are:
Unknown Unicast, Multicast & Broadcast Counts
Unicast, Multicast, and Broadcast traffic. & Broadcast Counts Multicast traffic together.
Broadcast Only Counts only Broadcast traffic.
Rate Threshold The maximum rate (packets per second) at which unknown packets are forwarded. The default value is 3500. The range is 70 -100000.
Network traffic is usually unpredictable, and the only basic assurance that can be offered is best effort traffic delivery. To overcome this challenge, Quality of Service (QoS) is applied throughout the network. This ensures that network traffic is prioritized according to specified criteria, and that specific traffic receives preferential treatment. QoS in the network optimizes network performance and entails two basic facilities: Classifying incoming traffic into handling classes, based on an attribute, including:
QOS > CoS Settings
The CoS Settings screen contains fields for enabling or disabling CoS. In addition, the Trust mode can be selected. The Trust mode relies on predefined fields within the packet to determine the egress queue settings. The CoS Settings screen has two areas, CoS Settings and CoS to Queue. CoS Mode Indicates if QoS is enabled on the interface. The possible values are:
Disable Disables QoS on the interface.
Basic Enables QoS on the interface. Advanced Enables Advanced mode QoS on the
% of WRR Bandwidth Displays the amount of bandwidth assigned to the queue. These values are fixed and are not user defined.
Class of Service Specifies the CoS priority tag values, where zero is the lowest and 7 is the highest. Queue Defines the traffic forwarding queue to which the CoS priority is mapped. Four traffic priority queues are supported. The Restore Defaults button restores the device factory defaults for mapping CoS values to a forwarding queue.
QoS > DSCP Settings
Interface Interface to which the CoS configuration applies. Default CoS Determines the default CoS value for incoming packets for which a VLAN tag is not defined. The possible field values are 0-7. The default CoS is 0. Restore Defaults Restores the device factory defaults for mapping CoS values to a forwarding queue. LAG LAG to which the CoS configuration applies.
QoS > Queue Settings
The DSCP Settings screen enables mapping DSCP values to specific queues. The DSCP Settings screen contains the following fields: DSCP Indicates the Differentiated Services Code Point value in the incoming packet. Queue Maps the DSCP value to the selected queue.
QoS > Bandwidth
The Queue Setting screen contains fields for defining the QoS queue forwarding types. Strict Priority Indicates that traffic scheduling for the selected queue is based strictly on the queue priority. WRR Indicates that traffic scheduling for the selected queue is based strictly on the WRR. Queue Displays the queue for which the queue settings are displayed. The possible field range is 1 - 4. WRR Weight Displays the WRR weights to queues.
8-Port 10/100 Ethernet Switch with Webview QoS > Bandwidth
The Bandwidth screen allows network managers to define the bandwidth settings for a specified egress interface.
Modifying queue scheduling affects the queue settings globally. The Bandwidth screen is not used with the Service mode, as bandwidth settings are based on services. Queue shaping can be based per queue and/or per interface. Shaping is determined by the lower specified value. The queue shaping type is selected in the Bandwidth screen. Interface Indicates the interface for which the queue shaping information is displayed. The possible field values are:
Ingress interfaces Source IP address and/or Source IP subnets.
ACE Filters in Access Control Lists (ACL) that determine which network traffic is forwarded. An ACE is based on the following criteria:
Protocol Protocol ID Source Port Destination Port Wildcard Mask Source IP Address Destination IP Address
ACL (Access Control List) Access Control Lists are used to grant, deny, or limit access devices, features, or applications. Auto-negotiation Allows 10/100 Mbps or 10/100/1000 Mbps Ethernet ports to automatically establish the optimal duplex mode, flow control, and speed. Back Pressure A mechanism used with Half Duplex mode that enables a port not to receive a message. Bandwidth The transmission capacity of a given device or network. Bandwidth Assignments Indicates the amount of bandwidth assigned to a specific application, user, and/or interface.
CoS (Class of Service) The 802.1p priority scheme. CoS provides a method for tagging packets with priority information. A CoS value between 0-7 is added to the Layer II header of packets, where zero is the lowest priority and seven is the highest. DDNS (Dynamic Domain Name System) Allows the hosting of a website, FTP server, or e-mail server with a fixed domain name (e.g., www.xyz.com) and a dynamic IP address. Default Gateway A device that forwards Internet traffic from your local area network. DHCP (Dynamic Host Configuration Protocol) A networking protocol that allows administrators to assign temporary IP addresses to network computers by leasing an IP address to a user for a limited amount of time, instead of assigning permanent IP addresses. DHCP Clients An Internet host using DHCP to obtain configuration parameters, such as a network address. DHCP Server An Internet host that returns configuration parameters to DHCP clients. DNS (Domain Name Server) The IP address of your ISPs server, which translates the names of websites into IP addresses. Domain A specific name for a network of computers. Download To receive a file transmitted over a network. DSL (Digital Subscriber Line) An always-on broadband connection over traditional phone lines. DSCP (DiffServ Code Point) Provides a method of tagging IP packets with QoS priority information. Dynamic IP Address A temporary IP address assigned by a DHCP server. EIGRP (Enhanced Interior Gateway Routing Protocol) Provides fast convergence, support for variablelength subnet mask, and supports multiple network layer protocols. Encryption Encoding data transmitted in a network. Ethernet IEEE standard network protocol that specifies how data is placed on and retrieved from a common transmission medium. Firmware The programming code that runs a networking device. Flow Control Enables lower speed devices to communicate with higher speed devices. This is implemented by the higher speed device refraining from sending packets. FTP (File Transfer Protocol) A protocol used to transfer files over a TCP/IP network.

7120510B-SM 8-Port 10/100 Ethernet Switch with Webview 80
Secure, reliable, intelligent, managed PoE switching for your growing business
Growing businesses require cost effective, networking solutions that can scale with ever changing business needs. The Linksys SRW208P WebView managed switch brings a whole new level of intelligence and security to the network infrastructure. The combination of its intelligence and small size make it ideal for a conference room or training room where security and uptime are important. It offers a two Gigabit copper or optical interfaces for connection to a core switch. For Wireless or VoIP deployments, the SRW208P supports IEEE802.3af standard for Power over Ethernet. With automatic load sensing, the power control circuitry automatically detects Power over Ethernet on end-device 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 4 ports or 7.5W per PoE port on 8 ports simultaneously. Independent overload and short-circuit protection for each port. LED indicators for power status per PoE port.
Network security is a top priority in any size business. Most business data networks, large and small, are unsecured. Unauthorized access to the network and mission critical data is a constant concern. The SRW208P is able to secure the network through 802.1X port authentication and MAC Filtering. 802.1X requires client to authenticate themselves before the port will pass data. Businesses are recognizing the benefits of doing Voice over IP (VoIP) and are quickly migrating their voice services to IP based platforms, requiring their local area networks to support both voice and data applications. In unmanaged IP networks, bursty data sessions can disrupt voice packet delivery, causing poor voice quality. With the enhanced QoS and traffic management features in the SRW208P, voice data can be prioritized, ensuring clear and reliable voice communications. Enabling the SRW208P advanced features further secures the integrity of your network. The WebView interface provides an intuitive, secure management interface enabling you to better utilize the comprehensive feature-set of the switch, resulting in a better optimized, more secure network.
Standards-based IEEE 802.3af PoE - Up to 4 ports at 15.4W or up to 8 ports at 7.5W. Dual gigabit uplinks provide increased bandwidth and redundancy. 802.1x port authentication and MAC address filtering brings network security down to the switch port level. Advance QoS enables the network to be optimized for your networked applications, including voice, video and data storage.
