How to Use this User Guide The User Guide to the WebView Switches has been designed to make understanding networking with the switch easier than ever. [. . . ] Indicates the number of packets that arrived on the interface in single-host mode, from a host whose MAC address is not the supplicant MAC address. Figure 5-34: Security - Multiple Hosts Security Tab - Storm Control Port. Indicates whether broadcast packet types are forwarded on the specific interface. The possible field values are: · Unknown Unicast, Multicast & Broadcast. The maximum rate (packets per second) at which unknown packets are forwarded. Figure 5-35: Security - Storm Control Chapter 5: Using the Web-based Utility for Configuration Security Tab - Storm Control 60 WebView Switches QoS 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: · The ingress interface · Packet content · A combination of these attributes Providing various mechanisms for determining the allocation of network resources to different handling classes, including: · The assignment of network traffic to a particular hardware queue · 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 handles per-flow settings, even within a single traffic class. QoS Tab - CoS Settings The CoS Settings screen contains fields for enabling or disabling CoS. The Trust mode relies on predefined fields within the packet to determine the egress queue settings. Figure 5-36: QoS - CoS Settings Chapter 5: Using the Web-based Utility for Configuration QoS 61 WebView Switches CoS Mode. Specifies the CoS priority tag values, where zero is the lowest and 7 is the highest. Defines the traffic forwarding queue to which the CoS priority is mapped. The Restore Defaults button restores the device factory defaults for mapping CoS values to a forwarding queue. CoS Default Interface. Determines the default CoS value for incoming packets for which a VLAN tag is not defined. Restores the device factory defaults for mapping CoS values to a forwarding queue. LAG to which the CoS configuration applies. QoS Tab - Queue Settings The Queue Setting screen contains fields for defining the QoS queue forwarding types. Indicates that traffic scheduling for the selected queue is based strictly on the queue priority. Indicates that traffic scheduling for the selected queue is based strictly on the WRR.
