[. . . ] From the ID drop-down list, select the static multicast ID that represents the multicast group that you want to view or modify. When you make your selection, the VID field and Multicast Entry fields change automatically. You can either assign all ports to or remove them from the static group in step 3, or assign individual ports to or remove them from the static multicast group in step 4. To assign all ports to or remove them from the static multicast group, select the check box to the left of Unit 1. To assign individual ports to or remove them from the static multicast group: a. To assign a port to or remove it from the static multicast group, select the check box under an individual port number. Switch Configuration The Switch Configuration menu lets you to enable or disable the Jumbo Frame support. When jumbo frame support is enabled, the frame size can vary from 64 to 9, 728 bytes. Address Table The Static Address table lists all the MAC addresses that you can specify. These addresses enable the switch to forward traffic from these MAC addresses. All source MAC addresses are trusted when the Trusted MAC list is empty. For information about the Trusted MAC list, see “Trusted MAC” on page 5-21. If the list includes MAC addresses, any incoming traffic with a source MAC address that is not included in the trusted MAC table is dropped. Select the check box to the left of the static address that you want to remove. Dynamic Address The Dynamic Address screen lets you to query the dynamically assigned MAC addresses by port, VLAN ID, and MAC address. Static MAC addresses might also be shown in the table entries that are returned by the query. The information that is returned from the query is displayed as follows: • ID. 0, December 2007 Configuring Switching Chapter 5 Configuring QoS and Security This chapter describes how to use the QoS tab and the Security tab: • • “Using the QoS Tab” “Using the Security Tab” Using the QoS Tab The navigation tabs on the top of the home page include a QoS tab that lets you manage your GS108T Gigabit Smart Switch using features under the following main menu commands and subcommnands: • “CoS” • “Basic—QoS Global Configuration” • “Basic—Rate Limit” • “Advanced—801. 1p to Queue Mapping” • “Advanced—DSCP Priority Mapping” The sections that follow in this chapter cover these features and tell you how to configure them in the GS108T Smart Switch. CoS The class of service (CoS) menu lets you classify specific traffic at the Layer 2 level by manipulating the CoS bits, thereby allowing you to configure quality of service (QoS). Basic—QoS Global Configuration There are two possible priority tag settings for the QoS; that is, there are two QoS modes: • 802. The QoS setting lets you map each of the eight priority levels to one of four internal hardware priority queues: High, Normal, Low, and Lowest. [. . . ] It is important that any untwisting be minimized to 3/8 inch (10 mm) for RJ-45 connections. If not correctly implemented, this can adversely affect all cabling settings. Near End Cross Talk Near End Cross Talk (NEXT) is a measure of the signal coupling from one wire to another, within a cable assembly, or among cables within a bundle. NEXT measures the amount of cross-talk disturbance energy that is detected at the near end of the link—the end where the transmitter is Network Cabling v1. [. . . ]
