Chapter 1 Switch Management

1.1 Management Options

After purchasing the switch, the user needs to configure the switch for network management. Switch provides two management options: in-band management and out-of-band management.

1.1.1 Out-Of-Band Management

Out-of-band management is the management through Console interface. Generally, the user will use out-of-band management for the initial switch configuration, or when in-band management is not available. For instance, the user must assign an IP address to the switch via the Console interface to be able to access the switch through Telnet.

The procedures for managing the switch via Console interface are listed below: Step 1: setting up the environment:

Connect with serial port

Out-of-band Management Configuration Environment

As shown in above, the serial port (RS-232) is connected to the switch with the serial cable provided. The table below lists all the devices used in the connection.

	Device Name			Description
	PC machine			Has functional keyboard and RS-232, with terminal emulator
				installed, such as HyperTerminal included in Windows
				9x/NT/2000/XP.
	Serial port cable			One end attach to the RS-232 serial port, the other end to the
				Console port.
	Switch			Functional Console port required.

Step 2: Entering the HyperTerminal

Switch>

The user can now enter commands to manage the switch. For a detailed description for the commands, please refer to the following chapters.

1.1.2 In-band Management

In-band management refers to the management by login to the switch using Telnet, or using HTTP, or using SNMP management software to configure the switch. In-band management enables management of the switch for some devices attached to the switch. In the case when in-band management fails due to switch configuration changes, out-of-band management can be used for configuring and managing the switch.

1.1.2.1 Management via Telnet

To manage the switch with Telnet, the following conditions should be met: 1. Switch has an IPv4/IPv6 address configured;

The host IP address (Telnet client) and the switch’s VLAN interface IPv4/IPv6 address is in the same network segment;

If 2. is not met, Telnet client can connect to an IPv4/IPv6 address of the switch via other devices, such as a router.

The switch is a Layer 2 switch that can be configured with several IP addresses, the configuration method refers to the relative chapter. The following example assumes the shipment status of the switch where only VLAN1 exists in the system.

The following describes the steps for a Telnet client to connect to the switch’s VLAN1 interface by Telnet(IPV4 address example):

Connected with cable

Manage the switch by Telnet

Step 1: Configure the IP addresses for the switch and start the Telnet Server function on the switch.

First is the configuration of host IP address. This should be within the same network segment as the switch VLAN1 interface IP address. Suppose the switch VLAN1 interface IP address is

10.1.128.251/24. Then, a possible host IP address is 10.1.128.252/24. Run “ping 10.1.128.251” from the host and verify the result, check for reasons if ping failed.

The IP address configuration commands for VLAN1 interface are listed below. Before in-band management, the switch must be configured with an IP address by out-of-band management (i.e. Console mode), the configuration commands are as follows (All switch configuration prompts are assumed to be “Switch” hereafter if not otherwise specified):

Switch>

Switch>enable

[phone] www.qtech.ru

Москва, Новозаводская ул., 18, стр. 1

21

Switch#config Switch(config)#interface vlan 1

Switch(Config-if-Vlan1)#ip address 10.1.128.251 255.255.255.0 Switch(Config-if-Vlan1)#no shutdown

To enable the Telnet Server function, users should type the CLI command telnet-server enable in the global mode as below:

Switch>enable

Switch#config

Switch(config)# telnet-server enable

Step 2: Run Telnet Client program.

Run Telnet client program included in Windows with the specified Telnet target.

Run telnet client program included in Windows

Step 3: Login to the switch.

Login to the Telnet configuration interface. Valid login name and password are required, otherwise the switch will reject Telnet access. This is a method to protect the switch from unauthorized access. As a result, when Telnet is enabled for configuring and managing the switch, username and password for authorized Telnet users must be configured with the following command: username <username> privilege <privilege> [password (0|7) <password>]. To open the local authentication style with the following command: authentication line vty login local. Privilege option must exist and just is 15. Assume an authorized user in the switch has a username of “test”, and password of “test”, the configuration procedure should like the following:

Switch>enable

Switch#config

[phone] www.qtech.ru

Москва, Новозаводская ул., 18, стр. 1

22

Switch(config)#username test privilege 15 password 0 test Switch(config)#authentication line vty login local

Enter valid login name and password in the Telnet configuration interface, Telnet user will be able to enter the switch’s CLI configuration interface. The commands used in the Telnet CLI interface after login is the same as that in the Console interface.

Telnet Configuration Interface

1.1.2.2 Management via HTTP

To manage the switch via HTTP, the following conditions should be met: 1. Switch has an IPv4/IPv6 address configured;

The host IPv4/IPv6 address (HTTP client) and the switch’s VLAN interface IPv4/IPv6 address are in the same network segment;

If 2. is not met, HTTP client should connect to an IPv4/IPv6 address of the switch via other devices, such as a router.

Similar to management the switch via Telnet, as soon as the host succeeds to ping/ping6 an IPv4/IPv6 address of the switch and to type the right login password, it can access the switch via HTTP. The configuration list is as below:

Step 1: Configure the IP addresses for the switch and start the HTTP server function on the switch.

For configuring the IP address on the switch through out-of-band management, see the telnet

23

management chapter.

To enable the WEB configuration, users should type the CLI command IP http server in the global mode as below:

Switch>enable

Switch#config Switch(config)#ip http server

Step 2: Run HTTP protocol on the host.

Open the Web browser on the host and type the IP address of the switch, or run directly the HTTP protocol on the Windows. For example, the IP address of the switch is “10.1.128.251”;

Run HTTP Protocol

When accessing a switch with IPv6 address, it is recommended to use the Firefox browser with 1.5 or later version. For example, if the IPv6 address of the switch is 3ffe:506:1:2::3. Input the IPv6 address of the switch is http://[3ffe:506:1:2::3] and the address should draw together with the square brackets.

Step 3: Login to the switch.

Login to the Web configuration interface. Valid login name and password are required, otherwise the switch will reject HTTP access. This is a method to protect the switch from unauthorized access. As a result, when Telnet is enabled for configuring and managing the switch, username and password for authorized Telnet users must be configured with the following command: username <username> privilege <privilege> [password (0|7) <password>]. To open the local authentication style with the following command: authentication line web login local. Privilege option must exist and just is 15. Assume an authorized user in the switch has a username of “admin”, and password of “admin”, the configuration procedure should like the following:

Switch>enable

25

Main Web Configuration Interface

Notice: When configure the switch, the name of the switch is composed with English letters.

1.1.2.3 Manage the Switch via SNMP Network Management Software

The necessities required by SNMP network management software to manage switches: 1. IP addresses are configured on the switch;

The IP address of the client host and that of the VLAN interface on the switch it subordinates to should be in the same segment;

If 2. is not met, the client should be able to reach an IP address of the switch through devices like routers;

SNMP should be enabled.

The host with SNMP network management software should be able to ping the IP address of the switch, so that, when running, SNMP network management software will be able to find it and implement read/write operation on it. Details about how to manage switches via SNMP network management software will not be covered in this manual, please refer to “Snmp network management software user manual”.

1.2 CLI Interface

The switch provides thress management interface for users: CLI (Command Line Interface) interface, Web interface, Snmp netword management software. We will introduce the CLI interface and Web configuration interface in details, Web interface is familiar with CLI interface function and will not be covered, please refer to “Snmp network management software user manual”.

[phone] www.qtech.ru

Москва, Новозаводская ул., 18, стр. 1

26

CLI interface is familiar to most users. As aforementioned, out-of-band management and Telnet login are all performed through CLI interface to manage the switch.

CLI Interface is supported by Shell program, which consists of a set of configuration commands. Those commands are categorized according to their functions in switch configuration and management. Each category represents a different configuration mode. The Shell for the switch is described below:

Configuration Modes

Configuration Syntax

Shortcut keys

Help function

Input verification

Fuzzy match support

1.2.1 Configuration Modes

Shell Configuration Modes

1.2.1.1 User Mode

On entering the CLI interface, entering user entry system first. If as common user, it is defaulted to User Mode. The prompt shown is “Switch>“, the symbol “>“ is the prompt for User

Mode. When exit command is run under Admin Mode, it will also return to the User Mode. Under User Mode, no configuration to the switch is allowed, only clock time and version

[phone] www.qtech.ru

Москва, Новозаводская ул., 18, стр. 1

27

information of the switch can be queries.

1.2.1.2 Admin Mode

To Admin Mode sees the following: In user entry system, if as Admin user, it is defaulted to

Admin Mode. Admin Mode prompt “Switch#” can be entered under the User Mode by running the enable command and entering corresponding access levels admin user password, if a password has been set. Or, when exit command is run under Global Mode, it will also return to the Admin Mode. Switch also provides a shortcut key sequence "Ctrl+z”, this allows an easy way to exit to Admin Mode from any configuration mode (except User Mode).

Under Admin Mode, the user can query the switch configuration information, connection status and traffic statistics of all ports; and the user can further enter the Global Mode from Admin Mode to modify all configurations of the switch. For this reason, a password must be set for entering Admin mode to prevent unauthorized access and malicious modification to the switch.

1.2.1.3 Global Mode

Type the config command under Admin Mode will enter the Global Mode prompt

“Switch(config)#”. Use the exit command under other configuration modes such as Port Mode,

VLAN mode will return to Global Mode.

The user can perform global configuration settings under Global Mode, such as MAC Table, Port Mirroring, VLAN creation, IGMP Snooping start and STP, etc. And the user can go further to Port Mode for configuration of all the interfaces.

1.2.1.4 Interface Mode

Use the interface command under Global Mode can enter the interface mode specified. Switch provides three interface type: 1. VLAN interface; 2. Ethernet port; 3. port-channel, accordingly the three interface configuration modes.

	Interface Type			Entry			Operates			Exit
	VLAN			Type interface vlan <Vlan-			Configure switch IPs,			Use the exit
	Interface			id> command under Global			etc			command to return to

1.2.1.5 VLAN Mode

Using the vlan <vlan-id> command under Global Mode can enter the corresponding VLAN Mode. Under VLAN Mode the user can configure all member ports of the corresponding VLAN. Run the exit command to exit the VLAN Mode to Global Mode.

1.2.1.6 DHCP Address Pool Mode

Type the ip dhcp pool <name> command under Global Mode will enter the DHCP Address

Pool Mode prompt “Switch(Config-<name>-dhcp)#”. DHCP address pool properties can be configured under DHCP Address Pool Mode. Run the exit command to exit the DHCP Address Pool Mode to Global Mode.

1.2.1.7 ACL Mode

	ACL type			Entry			Operates			Exit

	Extended IP			Type ip access-list			Configure parameters for			Use the exit
	ACL Mode			extanded command under			Extended IP ACL Mode.			command to return
				Global Mode.						to Global Mode.

1.2.2 Configuration Syntax

Switch provides various configuration commands. Although all the commands are different, they all abide by the syntax for Switch configuration commands. The general commands format of Switch is shown below:

cmdtxt <variable> {enum1 | … | enumN } [option1 | … | optionN]

Conventions: cmdtxt in bold font indicates a command keyword; <variable> indicates a variable parameter; {enum1 | … | enumN } indicates a mandatory parameter that should be selected from the parameter set enum1~enumN; and the square bracket ([ ]) in [option1 | … | optionN] indicate an optional parameter. There may be combinations of “< >“, “{ }” and “[ ]” in the command line, such as [<variable>], {enum1 <variable>| enum2}, [option1 [option2]], etc.

Here are examples for some actual configuration commands:

show version, no parameters required. This is a command with only a keyword and no parameter, just type in the command to run.

vlan <vlan-id>, parameter values are required after the keyword.
