    ES-305. 1.1 Overview The ES-305 is an intelligent five-port Ethernet switch. Use it to connect up to four devices to your network. The following figure shows the ES-305 (A) connecting several devices (1 ~ 4) and allowing them to communicate with one another and access the Internet through the Internet Service Provider’s network switch (B).

    Chapter 1 Introducing the ES-305 1.3 Good Habits for Managing the ES-305 Do the following things regularly to make the ES-305 more secure and to manage the ES-305 more effectively. • Change the username and password. Use a password that’s not easy to guess and that consists of different types of characters, such as numbers and letters.

    The management session automatically times out when the time period set in the Idle Time Out field in the Administrator Settings screen expires (default five minutes). Simply log back into the ES-305 if this happens. 2.3 Navigating the Web Configurator The bar at the top of the screen contains several icons.

    VLAN ID, or VID. 3.1.1 VLANs and the ES-305 The ES-305 lets you set up VLANs in two ways. In the VLAN > VLAN Group Settings screen, you can configure how the ES-305 deals with incoming frames by specifying which ports (LAN 1 ~ 4 and WAN) can belong to which VLANs (a port can accept frames from more than one VLAN).

  • Page 28: Figure 4 Tutorial: Vlan Group Settings Example

    The following figure shows how the Port VID Settings screen works. In this example, some of the data frames on the LAN 2 port arrive with VLAN information already in place, whereas other data frames do not have any. The ES-305 assigns a VLAN ID to the data frames without existing VLAN information.

  • Page 29: Example Scenario

    The following figure shows your network, and the VLANs you want to set up. The computer connected to the LAN 1 port on the ES-305 (A) can connect to the Internet, the IP phone connected to the LAN 2 port can connect to the VoIP service, and the computers connected to the LAN 2 and LAN 3 ports can communicate with one another.

  • Page 30: Figure 7 Tutorial: Three Vlans

    Take the following steps to configure this setup. 1 On a computer connected to the LAN 3 or 4 port, log into the ES-305 (see your Quick Start Guide for how to do this). Click VLAN > VLAN Group Settings. Here you can define which ports accept incoming traffic for each of your VLANs.

  • Page 31: Figure 8 Tutorial: Vlan Group Settings

    2 The first rule is the default preset rule that allows devices connected to any port to manage the ES-305 and freely exchange data. Do the following to modify the first rule to allow devices connected to the LAN 3 and 4 ports to communicate with one another and manage the ES-305.

  • Page 32: Figure 9 Tutorial: Vlan Group Settings Complete

    Figure 9 Tutorial: VLAN Group Settings Complete 6 Next, click VLAN > Port VID Settings. This screen allows you to specify the VLAN ID (VID) the ES-305 gives to data frames that arrive at each port without existing VLAN information.

  • Page 33: Figure 10 Tutorial: Port Vid Settings

    • In the WAN port’s PVID field, enter 600. In this scenario there should not be any traffic coming into the ES-305 on this port without a VLAN ID, but if there is it should be directed to LAN port 1. Furthermore, if you left the default PVID (1) the ES-305 could be managed through the WAN port.

  • Page 34: Using Snmp

    When you use the SNMP manager for the first time, or add a new device to your network, you must either scan the network for SNMP-capable devices (“nodes”) or specify each individual device’s IP address. In this example, you will scan for nodes. 1 Open the SNMP manager. Click Create New SNMP Node List. ES-305 User’s Guide...

    Subnet masks can be referred to by the size of the network number part (the bits with a “1” value). For example, an “8-bit mask” means that the first 8 bits of the mask are ones and the remaining 24 bits are zeroes. ES-305 User’s Guide...
