2 Operation of Web-based Management
Initial Configuration
This chapter instructs you how to configure and manage the GS-2300 series through the web user interface. With this facility, you can easily access and monitor through any one port of the switch all the status of the switch, including MIBs status, each port activity, spanning tree status, port aggregation status, multicast traffic, VLAN and priority status, illegal access record, etc.
The default values of the GS-2300 series are listed in the table below:
172.23.56.250IP Address
255.255.255.0Subnet Mask
172.23.56.254Default Gateway
adminUsername
Password
After the switch has finished the configuration of the interface, you can browse it. For instance, type http://172.23.56.250 in the address row in a browser, it will show the following screen and ask you to input your username and password in order to login and access authentication.
The default username is “admin” and the password is "admin". For the first time, please use the default username and password, and then click the <Login> button. The login process now is completed. In the login menu, you have to use the complete username and password respectively, the GS-2300 series will not give you a shortcut to a username automatically. This looks inconvenient, but is more secure.
In the GS-2300 series, the user management allows only one administrator to configure the system at the same time. If there are two or more users using administrator access, it will allow the one who logins first to configure the system. The rest of the users, even with administrator access, can only monitor the system. Those who have no administrator access can only monitor the system regardless. Only a maximum of three users are able to login simultaneously in the GS-2300 series.
When you first login on the Switch using the web to manage you must use the Username "admin". Default
5
password is "admin".
Both IPv4 and IPv6 is supported for management functions.
To optimize the display effect, we recommend you use Microsoft IE 6.0 above, Netscape V7.1 above or Firefox V1.00 above and have a resolution of 1024x768. The switch supports a neutral web browser interface.
admin
The GS-2300 series is set to DHCP by default. If you do not have a DHCP server to provide an ip address to the
5
switch, the default ip is 172.23.56.250

2.1 Connecting network devices

The switch is designed to be connected to 10, 100 or 1000Mbps network cards in PCs and servers, as well as to other switches and hubs. It may also be connected to remote devices using optional SFP transceivers.

2.2 Twisted-pair devices

Each device requires an unshielded twisted-pair (UTP) cable with RJ45 connectors at both ends. Use Category 5, 5e or 6 cable for 1000BASE-T connections, Category 5 or better for 100BASE-TX connections.

2.3 Cabling guidelines

The RJ45 ports on the switch support automatic MDI/MDI-X pin-out configuration, so you can use standard straight-through twisted-pair cables to connect to any other network device (PCs, servers, switches, routers, or hubs).
See Appendix B for further information on cabling.
CAUTION: Do not plug a phone jack connector into an RJ45 port. This will damage the switch. Use only twisted-pair
5
cables with RJ45 connectors that conform to FCC standards.
CONNECTING TO PCS, SERVERS, HUBS AND SWITCHES
Step 1: Attach one end of a twisted-pair cable segment to the device’s RJ45 connector.
Figure 16: Making Twisted-Pair Connections
Step 2: If the device is a network card and the switch is in the wiring closet, attach the other end of the cable segment to a modular wall outlet that is connected to the wiring closet. (See the section “Network Wiring Connections.”) Otherwise, attach the other end to an available port on the switch.
Make sure each twisted pair cable does not exceed 100 meters (328 ft) in length.
Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem. Otherwise
5
back pressure jamming signals may degrade overall performance for the segment attached to the hub.
Step 3: As each connection is made, the Link LED (on the switch) corresponding to each port will light green (1000 Mbps) or amber (100 Mbps) to indicate that the connection is valid.
NETWORK WIRING CONNECTIONS
Today, the patch-down block is an integral part of many of the newer equipment racks. It is actually part of the patch panel. Instructions for making connections in the wiring closet with this type of equipment follows.
10
Step 1: Attach one end of a patch cable to an available port on the switch, and the other end to the patch panel.
Step 2: If not already in place, attach one end of a cable segment to the back of the patch panel where the punch-down block is located, and the other end to a modular wall outlet.
Step 3: Label the cables to simplify future troubleshooting. See “Cable Labeling and Connection Records” .

The GS-2300 series access control list (ACL) is probably the most commonly used object in the IOS. It is used for packet filtering but also for selecting types of traffic to be analyzed, forwarded, or influenced in some way. The ACLs are divided into EtherTypes. IPv4, ARP protocol, MAC and VLAN parameters etc. Here we will just go over the standard and extended access lists for TCP/IP. As you create ACEs for ingress classification, you can assign a policy for each port, the policy number is 1-8. However, each policy can be applied to any port. This makes it very easy to determine what type of ACL policy you will be working with.
The section describes how to configure the ACL parameters (ACE) of the each switch port. These parameters will affect frames received on a port unless the frame matches a specific ACE.
Web Interface
To configure the ACL Ports in the web interface:
1. Click Configuration, ACL, then Ports
2. To scroll the specific parameter value to select the correct value for port ACL setting.
3. Click save to save the setting
4. If you want to cancel the setting then you need to click the reset button. It will revert to previously saved values.
5. After your configuration is complete you can see the counter of the port. Then you could click refresh to update the counter or clear the information.

3.2.3 Access Control List

The section describes how to configure Access Control List rules. An Access Control List (ACL) is a sequential list of permit or deny conditions that apply to IP addresses, MAC addresses, or other more specific criteria. This switch tests ingress packets against the conditions in an ACL one by one. A packet will be accepted as soon as it matches a permit rule, or dropped as soon as it matches a deny rule. If no rules match, the frame is accepted. Other actions can also be invoked when a matching packet is found, including rate limiting, copying matching packets to another port or to the system log, or shutting down a port.

3.3 Aggregation

You can bundle more than one port with the same speed, full duplex and the same MAC to be a single logical port, thus the logical port aggregates the bandwidth of these ports. This means you can apply your current Ethernet equipment’s to build the bandwidth aggregation. For example, if there are three Fast Ethernet ports aggregated in a logical port, then this logical port has bandwidth three times as high as a single Fast Ethernet port has.

3.3.1 Static Trunk

The Aggregation Configuration is used to configure the settings of Link Aggregation. You can bundle more than one port with the same speed, full duplex and the same MAC to be a single logical port, thus the logical port aggregates the bandwidth of these ports. This means you can apply your current Ethernet equipment’s to build the bandwidth aggregation.
3-3.1.1 Static Trunk
Ports using Static Trunk as their trunk method can choose their unique Static GroupID to form a logic “trunked port”. The benefit of using Static Trunk method is that a port can immediately become a member of a trunk group without any handshaking with its peer port. This is also a disadvantage because the peer ports of your static trunk group may not know that they should be aggregate together to form a “logic trunked port”. Using Static Trunk on both end of a link is strongly recommended. Please also note that low speed links will stay in “not ready” state when using static trunk to aggregate with high speed links.
Web Interface
To configure the Trunk Aggregation Hash mode and Aggregation Group in the web interface:
1. Click Configuration, Static Trunk, and then Aggregation Mode Configuration.

3.3.2 LACP

Ports using Link Aggregation Control Protocol (according to IEEE 802.3ad specification) as their trunking method can choose their unique LACP GroupID to form a logic “trunked port”. The benefit of using LACP is that a port makes an agreement with its peer port before it becomes a ready member of a “trunk group” (also called aggregator). LACP is safer than the other trunking method - static trunk.
3-3.2.1 Configuration
This page allows the user to inspect the current LACP port configurations, and possibly change them as well An LACP trunk group with more than one ready member-ports is a “real trunked” group. An LACP trunk group with only one or less than one ready member-ports is not a “real trunked” group.
