B. Configuration Examples This chapter contains information about how to configure the following features: • Virtual Local Area Networks (VLANs) • Access Control Lists (ACLs) • Differentiated Services (DiffServ) • 802.
GS752TP, GS728TP, and GS728TPP Gigabit Smart Switches Virtual Local Area Networks (VLANs) A local area network (LAN) can generally be defined as a broadcast domain. Hubs, bridges, or switches in the same physical segment or segments connect all end node devices. End nodes can communicate with each other without the need for a router. Routers connect LANs together, routing the traffic to the appropriate port.
GS752TP, GS728TP, and GS728TPP Gigabit Smart Switches • Packets leaving the switch are either tagged or untagged, depending on the setting for that port’s VLAN membership properties. A U for a given port means that packets leaving the switch from that port are untagged. Inversely, a T for a given port means that packets leaving the switch from that port are tagged with the VLAN ID that is associated with the port.
GS752TP, GS728TP, and GS728TPP Gigabit Smart Switches Access Control Lists (ACLs) ACLs ensure that only authorized users have access to specific resources while blocking off any unwarranted attempts to reach network resources. ACLs are used to provide traffic flow control, restrict contents of routing updates, decide which types of traffic are forwarded or blocked, and provide security for the network.
GS752TP, GS728TP, and GS728TPP Gigabit Smart Switches • Destination MAC Mask. 00:00:00:00:FF:FF • Source MAC. 02:02:1A:BC:DE:EF • Source MAC Mask. 00:00:00:00:FF:FF • VLAN ID. 2 For more information about MAC ACL rules, see MAC Rules on page 192. 3. In the MAC Binding Configuration screen, assign the Sales_ACL to Ethernet ports 6, 7, and 8 and click APPLY. For more information, see MAC Binding Configuration on page 194.
GS752TP, GS728TP, and GS728TPP Gigabit Smart Switches 1. In the IP ACL screen, create an IP ACL with an IP ACL ID of 1. For more information, see IP ACL on page 196. 2. In the IP Rules screen, create a rule for IP ACL 1 with the following settings: • Rule ID. 1 • Action. Deny • Match Every. False • Source IP Address. 192.168.187.0 • Source IP Mask. 255.255.255.0 For more information about IP ACL rules, see IP Rules on page 198. 3. Click Add. 4.
GS752TP, GS728TP, and GS728TPP Gigabit Smart Switches Differentiated Services (DiffServ) Standard IP-based networks are designed to provide best effort data delivery service. Best effort service implies that the network delivers the data in a timely fashion, although there is no guarantee that it will. During times of congestion, packets might be delayed, sent sporadically, or dropped.
GS752TP, GS728TP, and GS728TPP Gigabit Smart Switches • Layer 4 protocol (such as TCP or UDP) • Layer 4 source and destination ports • Source and destination IP addresses From a DiffServ point of view, there are two types of classes: • DiffServ traffic classes • DiffServ service levels or forwarding classes DiffServ Traffic Classes With DiffServ, you define which traffic classes to track on an ingress interface.
GS752TP, GS728TP, and GS728TPP Gigabit Smart Switches • Dropping. Drops a packet upon arrival. This is useful for emulating access control list operation using DiffServ, especially when DiffServ and ACL cannot co-exist on the same interface. • Marking IP DSCP. Marks and remarks the DiffServ code point in a packet with the DSCP value representing the service level associated with a particular DiffServ traffic class. • Marking CoS (802.1p). Sets the 3-bit priority field in the first or only 802.
GS752TP, GS728TP, and GS728TPP Gigabit Smart Switches 3. Configure the following settings for Class1: • Protocol Type. UDP • Source IP Address. 192.12.1.0 • Source Mask. 255.255.255.0 • Source L4 Port. Other, and enter 4567 as the source port value • Destination IP Address. 192.12.2.0 • Destination Mask. 255.255.255.0 • Destination L4 Port. Other, and enter 4568 as the destination port value For more information about this screen, see Class Configuration on page 147. 4. Click APPLY. 5.
GS752TP, GS728TP, and GS728TPP Gigabit Smart Switches Also the confirmed action on this flow is to send the packets with a committed rate of 10,000 Kbps and burst size of 128 KB. Packets that violate the committed rate and burst size are dropped. 802.1x Local area networks (LANs) are often deployed in environments that permit unauthorized devices to be physically attached to the LAN infrastructure, or permit unauthorized users to attempt to access the LAN through equipment already attached.
GS752TP, GS728TP, and GS728TPP Gigabit Smart Switches A port access entity (PAE) is able to adopt one of the following roles within an access control interaction: • Authenticator. A port that enforces authentication before allowing access to services available through that port. • Supplicant. A port that attempts to access services offered by the authenticator. • Authentication server.
GS752TP, GS728TP, and GS728TPP Gigabit Smart Switches You can configure more settings to control access to the network through the ports. See Port Security Interface Configuration on page 184 for information about the settings. 4. Click APPLY. 5. In the 802.1x Configuration screen, set the port-based authentication state and guest VLAN mode to Enable and click APPLY. For more information, see Port Security Interface Configuration on page 184.
GS752TP, GS728TP, and GS728TPP Gigabit Smart Switches MSTP Spanning Tree Protocol (STP) runs on bridged networks to help eliminate loops. If a bridge loop occurs, the network can become flooded with traffic. IEEE 802.1s Multiple Spanning Tree Protocol (MSTP) supports multiple instances of spanning tree to efficiently channel VLAN traffic over different interfaces. Each instance of the spanning tree behaves in the manner specified in IEEE 802.
GS752TP, GS728TP, and GS728TPP Gigabit Smart Switches receive and transmit MSTP BPDUs. The MST configuration identifier has the following components: 1. Configuration identifier format selector 2. Configuration name 3. Configuration revision level 4.

Use the VLAN Configuration screen to create VLANs 300 and 500. For more information, see VLAN Configuration on page 82. 2.
GS752TP, GS728TP, and GS728TPP Gigabit Smart Switches 5. In the CST Port Configuration screen, select ports g1–g8 and select Enable from the STP Status list. For more information, see CST Port Configuration on page 96. 6. Click APPLY. 7. Select ports g1–g5 (edge ports), and select Enable from the Fast Link list. Since the edge ports are not at risk for network loops, ports with Fast Link are enabled transition directly to the forwarding state. 8. Click APPLY.
GS752TP, GS728TP, and GS728TPP Gigabit Smart Switches Configure VLAN Routing with Static Route VLAN Routing Overview VLANs divide broadcast domains in a LAN environment. Whenever hosts in one VLAN need to communicate with hosts in another VLAN, the traffic must be routed between them. This is known as inter-VLAN routing. On NETGEAR switches it is accomplished by creating Layer 3 interfaces (switch virtual interfaces [SVI]).
GS752TP, GS728TP, and GS728TPP Gigabit Smart Switches Note: You can use the VLAN Routing Wizard for creating VLANs, adding ports, and enabling them for routing by assigning the IP address and mask.
