ES-3100 Series Switch Support Notes Separating a physical network into many virtual networks What is Virtual LAN? • VLAN Overview A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into multiple logical networks. Stations on a logical network belong to one group called VLAN Group. A station can belong to more than one group. The stations on the same VLAN group can communicate with each other.
ES-3100 Series Switch Support Notes outgoing ports allowed for each port when using port-based VLANs. Note that VLAN only governs the outgoing traffic, in the other word, it is unidirectional. Therefore, if you wish to allow two subscriber ports to talk to each other, e.g., between conference rooms in a hotel, you must define the egress (outgoing port) for both ports. An egress port is an outgoing port, that is, a port through which a data packet leaves.
ES-3100 Series Switch Support Notes Port-based VLAN definition: • • • • • • Egress port for port 1: port 2, port 4, port 5 Egress port for port 2: port 1, port 3 Egress port for port 3: port 2 Egress port for port 4: port 1, port 5 Egress port for port 5: port 1, port 4 Port-based VLAN across different switch Port-based VLAN is specific only to the switch on which it was created. Definitely, Port-based VLAN can't across different switches.
ES-3100 Series Switch Support Notes For Switch-2, port 1, port 2, and port 3 are allowed to communicate back and forth with uplink port 4, but not with other ports. • Switch-2 VLAN 1 member port: port 1 and port 4 • Switch-2 VLAN 2 member port: port 2 and port 4 • Switch-2 VLAN 3 member port: port 3 and port 4 For Switch-3, port 2, port 3, and port 4 are allowed to communicate back and forth with uplink port 1, but not with other ports.
ES-3100 Series Switch Support Notes For Switch-1, port 1, port2, and port 3 are allowed to communicate back and forth with uplink port 4, but not with other ports. • Switch-1 VLAN 1 member port: port 1 and port 4 • Switch-1 VLAN 2 member port: port 2 and port 4 • Switch-1 VLAN 3 member port: port 3 and port 4 How to configure Port-Based VLAN Port-based VLANs are VLANs where the packet forwarding decision is based on the destination MAC address and its associated port.
ES-3100 Series Switch Support Notes Scenario In this scenario, Port Based VLAN is used to separate one physical Switch into two smaller logical Switches. Port 1~4 and 9, 10 are in one group. And Port 5~10 are in another group. Port-based VLANs are specific only to the switch on which they were created. 34 All contents copyright (c) 2006 ZyXEL Communications Corporation.
ES-3100 Series Switch Support Notes Configuring your Switch to fulfill this scenario (GUI) 1. 2. 3. 4. Connect port 1 with a PC or Notebook via the RJ45 Cable. By default the MGMT IP on every port is 192.168.1.1/24 Set your NIC to 192.168.1.2/24 Open an Internet browser such as IE and give http://192.168.1.1 on the URL. 5. By default you will need to put “admin” as the username and “1234” as the password. 6. After you login successfully, you will see a similar screen like below. 7.
ES-3100 Series Switch Support Notes 8. Now, you need to tell the Switch how you are going to separate the physical Switch into some logical small Switches. Thus, we click “Advanced Application” then “VLAN”. On the right screen, check the boxes to suit your need. In this case, we need to make port 1~4 and port 9, 10 in a group in order for them to communicate in both ways. And port 5~10 in another group but these two groups cannot talk with each others.
ES-3100 Series Switch Support Notes 9. Finally, you can now verify your result. If everything works fine, PC A can ping PC B and PC Z. But it cannot ping PC C or PC D. On the same time, this should work vice versa. 10. For example, PC A: 192.168.1.4/24 PC B: 192.168.1.5/24 PC C: 192.168.1.6/24 PC D: 192.168.1.7/24 PC Z: 192.168.1.99/24 11.

ES-3100 Series Switch Support Notes Configuring your Switch to fulfill this scenario (CLI) 1. Connect the Switch Console port with your PC or Notebook. 2. Open your Terminal program.(Ex, Hyper Terminal in Windows System) 3. Make sure that your port settings are bps:9600 Data bits:8 Parity: None Stop bits:1 Flow control: None: 4. After you connected successfully, give the correct user name and password. 5. Put “en” or “enable” to go into the privileged mode.
ES-3100 Series Switch Support Notes scenario. 7. When all of the above are done, do not forget to give the “write memory” command under the enable mode to save your configuration. What is IEEE 802.1Q Tag-based VLAN? • Tag-based VLAN Overview Regarding IEEE 802.1Q standard, Tag-based VLAN uses an extra tag in the MAC header to identify the VLAN membership of a frame across bridges. This tag is used for VLAN and QoS (Quality of Service) priority identification.
ES-3100 Series Switch Support Notes process the frame across the network. A tagged frame is four bytes longer than an untagged frame and contains two bytes of TPID (Tag Protocol Identifier, residing within the type/length field of the Ethernet frame) and two bytes of TCI (Tag Control Information, starts after the source address field of the Ethernet frame). • TPID: TPID has a defined value of 8100 in hex. When a frame has the EtherType equal to 8100, this frame carries the tag IEEE 802.1Q / 802.1P.
ES-3100 Series Switch Support Notes • How 802.1Q VLAN works According to the VID information in the tag, the switch forward and filter the frames among ports. These ports with same VID can communicate with each other. IEEE 802.1Q VLAN function contains the following three tasks, Ingress Process, Forwarding Process and Egress Process. 1. Ingress Process: Each port is capable of passing tagged or untagged frames.
ES-3100 Series Switch Support Notes untagged frame is received, Ingress Process insert a tag contained the PVID into the untagged frame. Each physical port has a default VID called PVID (Port VID). PVID is assigned to untagged frames or priority tagged frames (frames with null (0) VID) received on this port. After Ingress Process, all frames have 4-bytes tag and VID information, and then go to Forwarding Process. 2.
ES-3100 Series Switch Support Notes 4. • Forbidden registration: This port is forbidden to be the egress port of specified VID.. • Fixed registration: While ad control is fixed registration, it means this is a static registration entry. This port is the egress port of the specified VID (a member port of the specified VLAN). The frames with specified VID tag can go through this port. • Normal registration: While ad control is normal registration, it means this is a dynamic registration entry.
ES-3100 Series Switch Support Notes Filtering Database. If the value is tagged, the outgoing frame on the egress port is tagged. If the value is untagged, the tag will be removed before frame leaves the egress port. How to connect two switches using VLAN? I want to make VLAN on two layer 2 switches, and I want to connect first switch to second switch with trunk port. There will be 5 VLAN on first Switch and there will be 7 VLAN on second switch. Trunk port will be port 25 on both switches as well.
ES-3100 Series Switch Support Notes ------------------------------------2. Configuration of VLAN on switch B Answer: ------------------------------------In switch A, add port 25 in each VLAN VID:101 (port 1,2,3,"25 TAG") VID:102 (port 4,5,6,,"25 TAG") VID:103 (port 7,8,9,10,"25 TAG") VID:104 (port 23,24,"25 TAG") VID:105 (port 11,12,13,14,"25 TAG") VID:106 (port 15,16,17,"25 TAG") VID:107 (port 18,19.
ES-3100 Series Switch Support Notes VID:102 (port 6,7,8,9,10,"25 TAG") VID:103 (port 11,12,13,14,"25 TAG") VID:104 (port 15,16,17,18,"25 TAG") VID:105 (port 19,20,21,23,22"25 TAG) Clients in same VLAN on both switches can communicate each other.
ES-3100 Series Switch Support Notes Setting up VLAN Trunking With the benefit of deploying VLAN trunking, we can connect two switches by a port that is configured as VLAN trunking port. PC1 with each VLAN tag frames from switch 1 can communicate with PC2 with another VLAN tag frames in switch 2 via VLAN trunking port. In our example, we set up port 5 in switch 1 as the VLAN Trunking port while in switch 2, we set up port 10 as the VLAN Trunking port.
ES-3100 Series Switch Support Notes In the switch 2, the configuration is In the switch 1, we set port 2 as VLAN 2 untag 49 All contents copyright (c) 2006 ZyXEL Communications Corporation.
ES-3100 Series Switch Support Notes In the switch 2, we set port 6 as VLAN 2 untag. The switch 1 IP address: 192.168.1.31 The switch 2 IP address: 192.168.1.21 After the configuration, we can observe that in the switch 1, the PC1 running on port 2 can find the PC2 running on port 6 in the switch 2. 50 All contents copyright (c) 2006 ZyXEL Communications Corporation.
ES-3100 Series Switch Support Notes How to configure GVRP? Description: In this scenario, PCs belong to different divisions within a single corporation can not communicate with each other, and we leave some ports of switches for GVRP-aware PC and others for VLAN-unaware PC.

ES-3100 Series Switch Support Notes IP Multicasting How to setup IGMP snooping in your switch? Figure 1: IGMP and IGMP snooping IGMP snooping is designed for application with deployment of multicast traffic. It operates on the underlying IGMP mechanism where a layer two switch passively listens to the IGMP Query, Report and Leave (IGMP version 2) packets transmitted between the IGMP router and clients and collects passing IGMP messages.
ES-3100 Series Switch Support Notes Configuration of IGMP snooping by web In this example, we enable the IGMP function on the GS-4024 (an IGMP router) to connect to a multimedia server. Also, we enable IGMP snooping function on the ES-3124 or other ZyXEL L2 Switch to connect to the multimedia clients. Figure 2: IGMP snooping Example Step one: In the GS-4024, click the IP Application, select IGMP where, IGMP function can be enabled and we can select either IGMP-v1 or IGMP-v2.
ES-3100 Series Switch Support Notes Step two: In the L2 Switch, click Basic Setting and then Switch Setup where we can enable IGMP snooping function with WEB-GUI. Figure 4: IGMP Snooping Setup Configuration of IGMP and IGMP snooping by CLI Step one: Enable IGMP function In the configure mode GS-4024(config)# router igmp Step two: Enable IGMP snooping 59 All contents copyright (c) 2006 ZyXEL Communications Corporation.

ES-3100 Series Switch Support Notes Overview of MVR MVR refers to Multicast VLAN Registration that enables a media server to transmit multicast stream in a single multicast VLAN while clients receiving multicast VLAN stream can reside in different VLANs. Clients in different VLANs intend to join or leave the multicast group simply by sending the IGMP Join/leave message to a receiver port. The receiver port belongs to one of the multicast group can receive multicast stream from media server.
ES-3100 Series Switch Support Notes Figure 2 MVR Mode Dynamic Mode If we select the dynamic mode in MVR setting, IGMP report message transmitted from the receiver port will be forwarded to a multicast router through its source port. Multicast router knows which multicast groups exist on which interface dynamically. Compatible mode If we select the dynamic mode in MVR setting, IGMP report message transmitted from the receiver port will not be transmitted to a multicast router.
ES-3100 Series Switch Support Notes configured multicast MAC address. If matches, the switch CPU modifies the hardware address table to include this receiver port and VLAN as a forwarding destination of the MVLAN Leave Operation Subscriber sends an IGMP leave message to the switch to leave the multicast. The switch CPU sends an IGMP group-specific query through the receiver port VLAN. If there is another subscriber in the VLAN, subscriber must respond within the max response time.
ES-3100 Series Switch Support Notes Scenario of MVR In the following section, we will provide an example to illustrate how to configure MVR. In this scenario, the media stream from the media servers will be transmitted from port 24 of GS-4024 (as an IGMP Router) to ES-3124 (L2 edge Switch) and GS-4012F.(work as L2 edge Switch). On Switch ES-3124 and GS4012F, we enabled the MVR function to allocate the multicast traffic from GS-4024 to separate VLAN hosts located on ES-3124 and GS-4012F.
ES-3100 Series Switch Support Notes Configuration via Web [GS-4024] 1. First of all, you need to create all those IP domains on the GS-4024 Switch. Once you completed those VLANs, your VLAN status should looks like the same as below. 2. Below are their related PVID settings. 65 All contents copyright (c) 2006 ZyXEL Communications Corporation.
ES-3100 Series Switch Support Notes 3. Right after the VLAN, you should add the IP domains to the related VLANs. 4. Since this GS-4024 works as an IGMP Router, you need to enable IGMP V2 on the multicast ip interface (which is the dummy interface). Please notice that since GS-4024 works here as an IGMP Router, you cannot enable IGMP Snooping on the same time because IGMP Snooping is a L2 feature. 66 All contents copyright (c) 2006 ZyXEL Communications Corporation.

ES-3100 Series Switch Support Notes To ring a network by building reducdent links and connections between Switch What is Spanning Tree Protocol • Spanning Tree Overview Spanning-Tree Protocol (STP) is a Layer 2 protocol designed to run on bridges and switches. The specification for STP is defined in IEEE 802.1d. The main purpose of STP is to ensure that you do not run into a loop situation when you have redundant paths in your network.
ES-3100 Series Switch Support Notes 2. Filtering Database Instability: When multiple copies of a frame arrive at different ports of a switch, the MAC entry instability in Filtering Database will occur. 1. 2. 3. Host sends an unicast frame to Router (source MAC address is Host's MAC, destination MAC address is Router's MAC). Both Switch A and Switch B will receive this frame and learn MAC address of Host on Port 2. Switch A has not yet learned the MAC address of Router.
ES-3100 Series Switch Support Notes How STP Works Spanning Tree provide a loop-free network. When a switch supported STP recognize a loop in the network topology, it blocks one or more redundant ports. Spanning Tree Protocol continually explore the network, so when the network topology changes, STP automatically reconfigure switch ports to avoid the failure by blocking certain port. Spanning tree algorithm aware switches (bridges) exchange configuration messages periodically.
ES-3100 Series Switch Support Notes 2. The bridge ID includes two parts, bridge priority (2 bytes) and bridge MAC address (6 bytes). The 802.1d default bridge priority is 32768. For example, a switch with default priority 32768 (8000 hex), MAC address is 00:A0:C5:12:34:56, its bridge ID is 8000:00A0:C512:3456. 3. On the root bridge, all its ports are designated ports. Designated ports are always in the forwarding state. While in forwarding state, a port can receive and send traffic. 2.
ES-3100 Series Switch Support Notes For each LAN segment (collision domain), there is a designated port. The designated port has the lowest cost to the root bridge. Designated ports are normally in the forwarding state to forward and receive traffic to the segment. If more than one port in the segment have the same path cost, the port on which bridge has lowest bridge ID is selected as a designated port. 1.
ES-3100 Series Switch Support Notes 1. Switch A bridge ID = 8000:00A0:C511:1111, Switch B bridge ID = 8000:00A0:C522:2222, Switch C bridge ID = 2. 3. 0001:00A0:C533:3333. Switch C has the lowest bridge ID, so Switch C is the root bridge. All ports of the root bridge are designated ports, so Port 1 is designated port. For non-root bridge Switch A, Port 1 path cost to root bridge is 19, Port 2 path cost is 119, 100 (Switch A Port 2) + 19 (Switch B Port 1).

ES-3100 Series Switch Support Notes Setting up Classifier & Policy rule to perform Access Control on your Switch Introduction on ACL ACL (Access Control List) is the name of a combination of Classifier and Policy Rule. A classifier groups traffic into data flows according to specific criteria such as the source address, destination address, source port number, destination port number or incoming port number.
ES-3100 Series Switch Support Notes higher weight of parameter just gets the highest weight at all. For example, you have defined the first classifier to have “Source Port” plus “Source Socket” as your rule parameters; and your second classifier has only “Destination Socket” as your rule parameter; at this time, since “Destination Socket” has a relative high weight comparing to “Source Port” or “Source Socket”, thus the second classifier will have a higher weight.

ES-3100 Series Switch Support Notes Overview of RMON Remote Monitoring (RMON) is a standard monitoring specification that enables various network monitors and console systems to exchange network-monitoring data. RMON provides network administrators with more freedom in selecting network-monitoring probes and consoles with features that meet their particular networking needs. RMON was originally developed to address the problem of managing LAN segments and remote sites from a central location.
ES-3100 Series Switch Support Notes requirements. Each group is optional so that vendors do not need to support all the groups within the Management Information Base (MIB). Some RMON groups require support of other RMON groups to function properly. Table 1 summarizes the nine monitoring groups specified in the RFC 1757 Ethernet RMON MIB.

ES-3100 Series Switch Support Notes Event (1.3.6.1.2.1.16.9) All groups in this MIB are optional. (MIB-II is mandatory) Scenario (ES-3100 Series supports RMON 1.2.3.9) In this illustration, SNMPc Enterprise Edition Version 5.1.6c is installed on the PC. And this PC is defined as “RMON management console”. This PC can ping both ZyXEL ES-3148 (both Switch A & Switch B). And there are some probes / networking devices to generate the traffic to the ZyXEL Switches in order to verify the RMON result.
ES-3100 Series Switch Support Notes In this scenario, we are going to monitor the Broadcast Packets by using the RMON MIB. The following will demonstrate the steps to monitor the Broadcast Packets by using SNMPc Enterprise Edition Version 5.1.6c. 1. Methodology of Scenario Verification 1.Open your SNMPc program first, then pick the ZyXEL-3148 Switch (it is first named as device “root”) and give it the correct IP information to get the SNMP information. Also, you can rename it to whatever you want.
