TCP/IP configuration at start-up from a server. You can configure the switch as a DHCP server or disable it. When configured as a server, the switch provides the TCP/IP configuration for the clients. If you disable the DHCP service, you must have another DHCP server on your LAN, or else the computer must be manually configured.
IP Multicast With IP multicast, the switch delivers IP packets to a group of hosts on the network - not everybody. In addition, the switch can send packets to Ethernet devices that are not VLAN- aware by untagging (removing the VLAN tags) IP multicast packets.
Page 32
DVMRP (Distance Vector Multicast Routing Protocol) is a protocol used for routing multicast data within an autonomous system (AS). DVMRP provides multicast forwarding capability to a layer 3 switch that runs both the IPv4 protocol (with IP Multicast support) and the IGMP protocol.
The ports allow the switch to connect to another Ethernet devices. Gigabit Ethernet Ports The ports allow the switch to connect to another WAN switch or daisy-chain to other switches. Mini-GBIC Slots Install SPF transceivers in these slots to connect to other Ethernet switches at longer distances than the Ethernet port.
This section shows a few examples of using the switch in various network environments. 1.4.1 Backbone Application In this application, the switch is an ideal solution for small networks where rapid growth can be expected in the near future. The switch can be used standalone for a group of heavy traffic users. You can connect computers directly to the switch’s port or connect other switches to the switch.
Figure 2 Bridging Application 1.4.3 High Performance Switched Example The switch is ideal for connecting two networks that need high bandwidth. In the following example, use trunking to connect these two networks. Switching to higher-speed LANs such as ATM (Asynchronous Transmission Mode) is not feasible for most people due to the expense of replacing all existing Ethernet cables and adapter cards, restructuring your network and complex maintenance.
In this example, only ports that need access to the server need belong to VLAN 1. Ports can belong to other VLAN groups too. Chapter 1 Getting to Know Your Switch ES-4024A User’s Guide Chapter 8, “VLAN,” on page...

5.1.1 Configuring an IP Interface On a layer-3 switch, an IP interface (also known as an IP routing domain) is not bound to a physical port. The default IP address of the switch is 192.168.1.1 with a subnet mask of 255.255.255.0.
6 Click Add. 5.1.2 Configuring DHCP Server Settings You can set the switch to assign network information (such as the IP address, DNS server, etc.) to DHCP clients on the network. For the example network, configure two DHCP client pools on the switch for the DHCP clients in the RD and Sales networks.
5.1.3 Creating a VLAN VLANs confine broadcast frames to the VLAN group in which the port(s) belongs. You can do this with port-based VLAN or tagged static VLAN with fixed port members. In this example, you want to configure port 10 as a member of VLAN 2. Figure 25 Initial Setup Network Example: VLAN 1 Click Advanced Application and VLAN in the navigation panel and click the Static VLAN link.

Chapter 8 on page 79 7.5 IGMP Snooping A switch can passively snoop on IGMP Query, Report and Leave (IGMP version 2) packets transferred between IP multicast routers/switches and IP multicast hosts to learn the IP multicast group membership. It checks IGMP packets passing through it, picks out the group registration information, and configures multicasting accordingly.
ES-4024A User’s Guide 7.6 Switch Setup Screen Click Basic Setting and then Switch Setup in the navigation panel to display the screen as shown. The VLAN setup screens change depending on whether you choose 802.1Q or Port Based in the VLAN Type field in this screen. Refer to the chapter on VLAN.
Use the next two fields to configure the priority level-to-physical queue mapping. The switch has four physical queues that you can map to the 8 priority levels. On the switch, traffic assigned to higher index queues gets through faster while traffic in lower index queues is dropped if the network is congested.
The factory default subnet mask is 255.255.255.0. On the switch, as a layer-3 device, an IP address is not bound to any physical ports. Since each IP address on the switch must be in a separate subnet, the configured IP address is also known as IP interface (or routing domain).

When auto-negotiation is turned on, a port on the switch negotiates with the peer automatically to determine the connection speed and duplex mode. If the peer port does not support auto-negotiation or turns off this feature, the switch determines the connection speed by detecting the signal on the cable and using half duplex mode.
The type of screen you see here depends on the VLAN Type you selected in the Switch Setup screen. This chapter shows you how to configure 802.1Q tagged and port-based VLANs. 8.1 Introduction to IEEE 802.1Q Tagged VLAN A tagged VLAN uses an explicit tag (VLAN ID) in the MAC header to identify the VLAN membership of a frame across bridges - they are not confined to the switch on which they were created.
GVRP (GARP VLAN Registration Protocol) is a registration protocol that defines a way for switches to register necessary VLAN members on ports across the network. Enable this function to permit VLANs groups beyond the local switch. Please refer to the following table for common IEEE 802.1Q VLAN terminology.
C, D and E; otherwise they will drop frames with unknown VLAN group tags. However, with VLAN Trunking enabled on a port(s) in each intermediary switch you only need to create VLAN groups in the end devices (A and B). C, D and E automatically allow frames with VLAN group tags 1 and 2 (VLAN groups that are unknown to those switches) to pass through their VLAN trunking port(s).

On each bridge, the root port is the port through which this bridge communicates with the root. It is the port on this switch with the lowest path cost to the root (the root path cost). If there is no root port, then this switch has been accepted as the root bridge of the spanning tree network.
ES-4024A User’s Guide 11.1.2 How STP Works After a bridge determines the lowest cost-spanning tree with STP, it enables the root port and the ports that are the designated ports for connected LANs, and disables all other ports that participate in STP. Network packets are therefore only forwarded between enabled ports, eliminating any possible network loops.
This switch may also be the root bridge. Bridge ID This is the unique identifier for this bridge, consisting of bridge priority plus MAC address. This ID is the same for Root and Our Bridge if the switch is the root switch. Hello Time...

This chapter shows you how to logically aggregate physical links to form one logical, higher- bandwidth link. 15.1 Overview Link aggregation (trunking) is the grouping of physical ports into one logical higher-capacity link. You may want to trunk ports if for example, it is cheaper to use multiple lower-speed links than to under-utilize a high-speed, but more costly, single-port link.
ES-4024A User’s Guide • You must connect all ports point-to-point to the same Ethernet switch and configure the ports for LACP trunking. • LACP only works on full-duplex links. • All ports in the same trunk group must have the same media type, speed, duplex mode and flow control settings.

39.2 VLAN Databases A VLAN database stores and organizes VLAN registration information useful for switching frames to and from a switch. A VLAN database consists of a static entries (Static VLAN or SVLAN table) and dynamic entries (Dynamic VLAN or DVLAN table).
ES-4024A User’s Guide 39.2.2 Dynamic Entries (DVLAN Table) Dynamic entries are learned by the switch and cannot be created or updated by administrators. The switch learns this information by observing what port, source address and VLAN ID (or VID) is associated with a frame. Entries are added and deleted using GARP VLAN Registration Protocol (GVRP), where GARP is the Generic Attribute Registration Protocol.
This section shows you how to configure and monitor the IEEE 802.1Q Tagged VLAN. 39.4.1 GARP Status Syntax: show garp This command shows the switch’s GARP timer settings, including the join, leave and leave all timers. An example is shown next. Figure 164 GARP STATUS Command Example...
<msec> leaveall <msec> This command sets the switch’s GARP timer settings, including the join, leave and leave all timers. Switches join VLANs by making a declaration. A declaration is made by issuing a Join message using GARP. Declarations are withdrawn by issuing a Leave message. A Leave All message terminates all registrations.
This command turns on GVRP in order to propagate VLAN information beyond the switch. 39.4.5 Disable GVRP Syntax: no vlan1q gvrp This command turns off GVRP so that the switch does not propagate VLAN information to other switches. 39.5 Port VLAN Commands You must configure the switch port VLAN settings in config-interface mode.

IP Addressing Routers “route” based on the network number. The router that delivers the data packet to the correct destination host uses the host ID. IP Classes An IP address is made up of four octets (eight bits), written in dotted decimal notation, for example, 192.168.1.1.
ES-4024A User’s Guide Since the first octet of a class “A” IP address must contain a “0”, the first octet of a class “A” address can have a value of 0 to 127. Similarly the first octet of a class “B” must begin with “10”, therefore the first octet of a class “B”...
Since the mask is always a continuous number of ones beginning from the left, followed by a continuous number of zeros for the remainder of the 32 bit mask, you can simply specify the number of ones instead of writing the value of each octet. This is usually specified by writing a “/”...
ES-4024A User’s Guide Note: In the following charts, shaded/bolded last octet bit values indicate host ID bits “borrowed” to form network ID bits. The number of “borrowed” host ID bits determines the number of subnets you can have. The remaining number of host ID bits (after “borrowing”) determines the number of hosts you can have on each subnet.
Example: Four Subnets The above example illustrated using a 25-bit subnet mask to divide a class “C” address space into two subnets. Similarly to divide a class “C” address into four subnets, you need to “borrow” two host ID bits to give four possible combinations of 00, 01, 10 and 11. The subnet mask is 26 bits (11111111.11111111.11111111.11000000) or 255.255.255.192.

The following table shows class C IP address last octet values for each subnet. Table 105 Eight Subnets SUBNET SUBNET ADDRESS FIRST ADDRESS...
Subnetting With Class A and Class B Networks. For class “A” and class “B” addresses the subnet mask also determines which bits are part of the network number and which are part of the host ID. A class “B” address has two host ID octets available for subnetting and a class “A” address has three host ID octets (see The following table is a summary for class “B”...
