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.
Page 33: Applications
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.
Page 34: High Performance Switched Example
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.

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.

Page 78: Chapter 8 Vlan
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.
Page 79: Automatic Vlan Registration
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.
Page 80: Port Vlan Trunking
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).

Page 95: How Stp Works
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.

This allows you to control the distribution of multicast services (such as content information distribution) based on service plans and types of subscription. You can set the switch to filter the multicast group join reports on a per-port basis by configuring an IGMP filtering profile and associating the profile to a port.
Page 125: Multicast Status
ES-2024 Series User’s Guide The switch forwards multicast traffic destined for multicast groups (that it has learned from IGMP snooping or that you have manually configured) to ports that are members of that group. IGMP snooping generates no additional network traffic, allowing you to significantly reduce multicast traffic passing through your switch.

Page 129: Types Of Mvr Ports
Figure 59 MVR Network Example 19.5.1 Types of MVR Ports In MVR, a source port is a port on the switch that can send and receive multicast traffic in a multicast VLAN while a receiver port can only receive multicast data. Once configured, the switch maintains a forwarding table that matches the multicast stream to the associated multicast group.
Page 130: General Mvr Configuration
When the subscriber changes the channel or turns off the computer, an IGMP leave message is sent to the switch to leave the multicast group. The switch sends a query to VLAN 1 on the receiver port (in this case, a DSL port on the switch). If there is another subscriber device connected to this port in the same subscriber VLAN, the receiving port will still be on the list of forwarding destination for the multicast traffic.

Page 244: Modify Static Vlan
34.3.4.2 Forwarding Process Example 34.3.4.2.1 Tagged Frames 1 First the switch checks the VLAN ID (VID) of tagged frames or assigns temporary VIDs to untagged frames. 2 The switch then checks the VID in a frame’s tag against the SVLAN table.
Page 245: Delete Vlan Id
The switch also does not forward frames to “forbidden” ports. 4 If after looking at the SVLAN, the switch does not have any ports to which it will send the frame, it won’t check the port filter.
Page 246: Disable Vlan
• VID is the VLAN identification number. • Status shows whether the VLAN is static or active. • Elap-Time is the time since the VLAN was created on the switch. • The section of the last column shows which ports are tagged and which are TagCtl untagged.

Page 262: Introduction To Ip Addresses
IP Addresses and Subnetting This appendix introduces IP addresses, IP address classes and subnet masks. You use subnet masks to subdivide a network into smaller logical networks. Introduction to IP Addresses An IP address has two parts: the network number and the host ID. Routers use the network number to send packets to the correct network, while the host ID identifies a single device on the network.
Page 263: Table 82 Classes Of Ip Addresses
ES-2024 Series User’s Guide The following table shows the network number and host ID arrangement for classes A, B and Table 82 Classes of IP Addresses IP ADDRESS OCTET 1 Class A Network number Class B Network number Class C Network number An IP address with host IDs of all zeros is the IP address of the network (192.168.1.0 for example).
Page 264: Table 84 "Natural" Masks
Subnet Masks A subnet mask is used to determine which bits are part of the network number, and which bits are part of the host ID (using a logical AND operation). A subnet mask has 32 bits. If a bit in the subnet mask is a “1” then the corresponding bit in the IP address is part of the network number.
