2 Use VLANS for Traffic Segmentation This chapter covers the following topics: • • • • • • • • VLAN overview Create basic port-based VLANs Assign ports to multiple port-based VLANs Create 802.1Q-based VLANs in a basic configuration Create 802.1Q-based VLANs in an advanced configuration Add tagged or untagged ports to an 802.1Q-based VLAN Specify a port PVID for an 802.
48-Port Gigabit Ethernet Plus Switch with 2 SFP Ports Model GS750E VLAN overview Virtual LANs (VLANs) are made up of networked devices that are grouped logically into separate networks. You can group ports on a switch to create a virtual network made up of the devices connected to the ports. Ports can be grouped in VLANs using port-based or 802.1Q criteria: • Port-based VLANs. Assign ports to virtual networks. Ports with the same VLAN ID are placed in the same VLAN.
48-Port Gigabit Ethernet Plus Switch with 2 SFP Ports Model GS750E The default password is password. The password is case-sensitive. The Switch Information page displays. 5. Select VLAN. The Basic Port-based VLAN Status page displays. 6. If this is the first time that you are accessing this page or if you are changing the VLAN assignment method, select the Enable radio button and continue with Step 7. Otherwise, see Step 9. A pop-up window opens, informing you that the current VLAN settings will be lost.
48-Port Gigabit Ethernet Plus Switch with 2 SFP Ports Model GS750E Assign ports to multiple port-based VLANs A port-based VLAN configuration lets you assign ports on the switch to a VLAN. The number of VLANs is limited to the number of ports on the switch. In an advanced port-based VLAN configuration, you can assign a single port to multiple VLANs. By default, all ports are members of VLAN 1. To assign ports to multiple port-based VLANs: 1. Connect your computer to the same network as the switch.

3 Optimize Performance With Quality of Service This chapter covers the following topics: • • • • Enable 802.
48-Port Gigabit Ethernet Plus Switch with 2 SFP Ports Model GS750E Enable 802.1p/DSCP-based quality of service 802.1p/DSCP-based priority uses a field in the data packet header that identifies the class of data in the packet (for example, voice or video). When 802.1p/DSCP-based priority is used, the switch reads information in the packet header to determine the priority to assign to the packet. The switch reads both 802.1p tag information and DSCP/ToS tag information.
48-Port Gigabit Ethernet Plus Switch with 2 SFP Ports Model GS750E Configure port-based quality of service You can assign a priority to all data passing through a particular port. Data with a higher priority is transmitted faster. If packets arrive at several ports at the same time, the ports configured as higher priority transmit their packets first. You must determine which ports will carry delay-sensitive data. To configure port-based QoS: 1. Connect your computer to the same network as the switch.
48-Port Gigabit Ethernet Plus Switch with 2 SFP Ports Model GS750E Your settings are saved and the Port Priority table displays. 9. To set the port priority for one or more ports, do the following: a. Select one or more ports. b. In the Priority menu, select the priority. c. Click the Apply button. Your settings are saved. The same priority is applied to all ports that you selected. 10. To set a different port priority for one or more other ports, repeat Step 9.
48-Port Gigabit Ethernet Plus Switch with 2 SFP Ports Model GS750E If you do not know the IP address of the switch, see Access the switch using a web browser on page 7. The login page displays. 4. Enter the switch password. The default password is password. The password is case-sensitive. The Switch Information page displays. 5. Select QoS > Rate Limit. 6. Set the ingress (incoming) and egress (outgoing) traffic rates by doing the following: a. Select one or more ports. b.
48-Port Gigabit Ethernet Plus Switch with 2 SFP Ports Model GS750E you to select a storm control rate for each port. Others assign a predetermined storm control rate for all ports on the switch. If broadcast traffic on any port exceeds the threshold that you set, the switch temporarily blocks (discards) the broadcast packets. To set up broadcast filtering: 1. Connect your computer to the same network as the switch.
48-Port Gigabit Ethernet Plus Switch with 2 SFP Ports Model GS750E Your settings are saved and the Storm Control Rate table displays. 8. Set the storm control rate by doing the following: a.
