253 B B. C onf igur ati on Ex am pl es This chapter contains information about how to configure the following features: • Virtual Local Area Networks (VLANs) • Access Control Lists (ACLs) • Differentiated Services (DiffServ) • 802.
254 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.
255 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.
256 GS752TP , GS728TP , and GS728TPP Gigabit Smart Switches Access Control Lists (A CLs) ACLs ensure that only authorized users have access to specific resources while blocking of f any unwarranted attempts to reach network resources.
257 GS752TP , GS728TP , and GS728TPP Gigabit Smart Switches • Destination MAC . 01:02:1A:BC:DE:EF • 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 191.
258 GS752TP , GS728TP , and GS728TPP Gigabit Smart Switches departments. T raf fic from the Finance department is identified by each packet’s network IP address. 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 195.
259 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.
260 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 p.
261 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 Dif fServ and ACL cannot co-exist on the same interface.
262 GS752TP , GS728TP , and GS728TPP Gigabit Smart Switches 3. Configure the following settings for Class1: • Protocol T ype . 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 .
263 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.
264 GS752TP , GS728TP , and GS728TPP Gigabit Smart Switches Access control is achieved by enforcing authentication of supplicants that are attached to a controlled ports of the authenticator . The result of the authentication process determines whether the supplicant is authorized to access services on that controlled port.
265 GS752TP , GS728TP , and GS728TPP Gigabit Smart Switches a force-authorized state and does not require any authentication. When the Port Control setting is Auto, the authenticator P AE sets the controlled port mode. 3. In the Guest VLAN field for ports g1–g8, enter 150 to assign these ports to the guest VLAN.
266 GS752TP , GS728TP , and GS728TPP Gigabit Smart Switches MSTP Spanning T ree Protocol (STP) runs on bridged networks to help eliminate loops. If a bridge loop occurs, the network can become flooded with traffic.
267 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.
268 GS752TP , GS728TP , and GS728TPP Gigabit Smart Switches In this example, ports g1–g5 are connected to host stations, so those links are not subject to network loops.
269 GS752TP , GS728TP , and GS728TPP Gigabit Smart Switches For more information, see CST Configuration on page 94. 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.
270 GS752TP , GS728TP , and GS728TPP Gigabit Smart Switches Configure VLAN R outing with Static Route VLAN R outing 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.
271 GS752TP , GS728TP , and GS728TPP Gigabit Smart Switches Note: Y ou can use the VLAN Routing Wizard for creating VLANs, adding ports, and enabling them for routing by assigning the IP address and mask.
