Setting Up for Management 19

Setting Up for Management

Methods of Managing a Switch

To make full use of the features offered by your switch, and to change and monitor the way it works, you have to access the management software that resides on the switch. This is known as managing the switch. Managing the switch can help you to improve the efficiency of the switch and therefore the overall performance of your network.
This section explains the initial set up of the switch and the different methods of accessing the management software to manage a switch. It covers the following topics:
Methods of Managing a Switch
Switch Setup Overview
Manually set the IP Address using the Console Port
Viewing IP Information using the Console Port
Setting Up Web Interface Management
Setting Up SNMP Management V1 or V2
Default Users and Passwords
To manage your switch you can use one of the following methods:

Web Interface Management

Web Interface
Management
SNMP Management
In addition, you can use the Command Line Interface through the Console port for basic operations of the switch including setting and viewing the IP address, configuring user accounts, upgrading switch firmware, and more. Refer to
“3Com CLI Reference Guide” on page 227.
Each switch has an internal set of web pages that allow you to manage the switch using a Web browser remotely over an IP network (see Figure 2).

CAUTION To protect your switch from unauthorized access, you must change the default password as soon as possible, even if you do not intend to actively manage your switch. For more information on default users and changing default passwords, see
“Default Users and
Passwords” on page 29.
22 CHAPTER 1: GETTING STARTED

IP Configuration The switch’s IP configuration is determined automatically using DHCP, or

manually using values you assign.
Automatic IP Configuration using DHCP
By default the switch tries to configure its IP Information without requesting user intervention. It tries to obtain an IP address from a DHCP server on the network.
Default IP Address If no DHCP server is detected, the switch will use its default IP information. The default IP address is 169.254.x.y, where x and y are the last two bytes of its MAC address.
Note: The switch’s default IP address is listed on a label located on the rear of the switch.
If you use automatic IP configuration it is important that the IP address of the switch is static, otherwise the DHCP server can change the switch’s IP addresses and it will be difficult to manage. Most DHCP servers allow static IP addresses to be configured so that you know what IP address will be allocated to the switch. Refer to the documentation that accompanies your DHCP server.
You should use the automatic IP configuration method if:
your network uses DHCP to allocate IP information, or
flexibility is needed. If the switch is deployed onto a different subnet, it
will automatically reconfigure itself with an appropriate IP address, instead of you having to manually reconfigure the switch.
If you use the automatic IP configuration method, you need to discover the automatically allocated IP information before you can begin management. Work through the
“Viewing IP Information using the
Console Port” on page 25.
Manual IP Configuration
When you configure the IP information manually, the switch remembers the information that you enter until you change it again.
You should use the Manual IP configuration method if:
You do not have a DHCP server on your network, or
You want to remove the risk of the IP address ever changing, or
Using the Command Line Interface (CLI) 23
Your DHCP server does not allow you to allocate static IP addresses.
(Static IP addresses are necessary to ensure that the switch is always
allocated the same IP information.)
For most installations, 3Com recommends that you configure the switch IP information manually. This makes management simpler and more reliable as it is not dependent on a DHCP server, and eliminates the risk of the IP address changing.
To manually enter IP information for your switch, work through the “Manually set the IP Address using the Console Port” on page 24.

Using the Command Line Interface (CLI)

Connecting to the
Console Port
You can access the switch through the Console port to manually set the IP address, or to view the IP address that was assigned automatically (for example, by a DHCP server).
For more information about the CLI, refer to “3Com CLI Reference Guide” on page 227.
This section describes how to connect to your switch through the Console port.
Prerequisites
A workstation with terminal emulation software installed, such as
Microsoft Hyperterminal. This software allows you to communicate
with the switch using the console port directly.
Documentation supplied with the terminal emulation software.
The console cable (RJ-45) supplied with your switch.
You can find pin-out diagrams for the cable in Appendix C on page 221.
24 CHAPTER 1: GETTING STARTED
Connecting the Workstation to the Switch
1 Connect the workstation to the console port using the console cable as
shown in
Figure 5 Connecting a Workstation to the Switch using the Console Port
To connect the cable:
a Attach the cable’s RJ-45 connector to the Console port of the switch.
b Attach the other end of the cable to the workstation.

Defining Access Control Lists

Access Control Lists (ACLs) allow network managers to define classification actions and rules for specific ingress ports. A network manager can configure an ACL on an ingress port so that packets are either admitted or denied entry. The user can also specify that when packets are denied entry, the ingress port is also disabled.
For example, an ACL rule is defined stating that port number 20 can receive TCP packets, however, if a UDP packet is received, the packet is dropped. ACLs are composed of access control entries (ACEs) that are made of the filters that determine traffic classifications.
The following are examples of filters that can be defined as ACEs:
Source Port IP Address and Wildcard Mask — Filters the packets
by the source port IP address and wildcard mask.
Destination Port IP Address and Wildcard Mask — Filters the
packets by the destination port IP address and wildcard mask.
ACE Priority — Filters the packets by the ACE priority.
Protocol — Filters the packets by the IP protocol.
DSCP — Filters the packets by the DiffServ Code Point (DSCP) value.
IP Precedence — Filters the packets by the IP Precedence.
Action — Indicates the action assigned to the packet matching the
ACL. Packets are forwarded or dropped. In addition, the port can be shut down, a trap can be sent to the network administrator, or packet is assigned rate limiting restrictions for forwarding.

Broadcast Storm limits the amount of Multicast and Broadcast frames accepted and forwarded by the device. When Layer 2 frames are forwarded, Broadcast and Multicast frames are flooded to all ports on the relevant VLAN. This occupies bandwidth, and loads all nodes on all ports.
A Broadcast Storm is a result of an excessive amount of broadcast messages simultaneously transmitted across a network by a single port. Forwarded message responses are heaped onto the network, straining network resources or causing the network to time out.
Broadcast Storm is enabled for all Gigabit ports by defining the packet type and the rate the packets are transmitted. The system measures the incoming Broadcast and Multicast frame rates separately on each port, and discards the frames when the rate exceeds a user-defined rate.
Packet threshold is ignored if Broadcast Storm Control is Disabled.
