Chapter 1 Switch Management
1.1 Management Options
After purchasing the switch, the user needs to configure the switch for network management.
SS2GR50i/26i series 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.
The procedures for managing the switch via Console interface are listed below:
Step 1: setting up the environment:
Fig 1-1 Out-of-band Management Configuration Environment
As shown in Fig 1-1, 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

Switch Configuration SS2GR50i / SS2GR26i / SS2GR26ip

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
Open the HyperTerminal included in Windows after the connection established. The example below
is based on the HyperTerminal included in Windows XP.
1）Click Start menu - All Programs -Accessories -Communication - HyperTerminal.
Fig 1-2 Opening HyperTerminal 1
2) Type a name for opening HyperTerminal, such as ‘Switch’.

Switch Configuration SS2GR50i / SS2GR26i / SS2GR26ip

Fig 1-3 Opening HyperTerminal 2
3) In the ‘Connecting using’ drop-list, select the RS-232 serial port used by the PC, e.g. COM1, and
click ‘OK’.
Fig 1-4 Opening HyperTerminal 3
4) COM1 property appears, select ‘9600’ for ‘Baud rate’, ‘8’ for ‘Data bits’, ‘none’ for ‘Parity
checksum’, ‘1’ for stop bit and ‘none’ for traffic control; or you can also click ‘Restore default’ and
click ‘OK’.

Step 3: Entering switch CLI interface
Power on the switch, the following appears in the HyperTerminal windows, that is the CLI
configuration mode for SS2GR50i/26i series Switch.
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 via Telnet ,HTTP protocol, or
using the snmp network management software developed by Amer.com or other parties 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:

Switch Configuration SS2GR50i / SS2GR26i / SS2GR26ip
5
1) Switch has an IPv4/IPv6 address configured
2) The host IP address (Telnet client) and the switch’s VLAN interface IPv4/IPv6 address is in
the same network segment.
3) If not 2), Telnet client can connect to an IPv4/IPv6 address of the switch via other devices,
such as a router.
SS2GR50i/26i series switch is a Layer 3 switch that can be configured with several IPv4/IPv6
addresses. 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 for example).
Fig 1-6 Manage the switch by Telnet
Step 1: Configure the IP addresses for 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 VLAN interface IP address 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’ here after if not otherwise specified):
Switch>
Switch>enable
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
Step 2: Run Telnet Client program.

Switch Configuration SS2GR50i / SS2GR26i / SS2GR26ip
6
Run Telnet client program included in Windows with the specified Telnet target.
Fig 1-7 Run telnet client program included in Windows
Step 3: Login to the switch
Login 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 <user> password {0|7} <password>.
Assume an authorized user in the switch has a username of ‘test’, and password of ‘test’, the
configuration procedure should like the following:
Switch>en
Switch#config
Switch(Config)#telnet-user test password 0 test
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
2) The host IPv4/IPv6 address (HTTP client) and the switch’s VLAN interface IPv4/IPv6
address are in the same network segment;
3) 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 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 relevant
chapter.
To enable the WEB configuration, users should type the CLI command ip http server in the global
mode as below:
Switch>en
Switch#config
Switch(Config)#ip http server
Step 2: Using 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’.

Fig 1-9 Connect through 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’, enter the switch
address at the address bar: http://[3ffe:506:1:2::3], where the address should be in the square
brackets.
Step 3: Logon to the switch
To logon to the HTTP configuration interface, valid login user name and password are required;
otherwise the switch will reject HTTP access. This is a method to protect the switch from the
unauthorized access.
Consequently, in order to configure the switch via HTTP, username and password for authorized
HTTP users must be configured with the following command in the global mode:
username <username> password <show_flag> <password>.
Suppose an authorized user in the switch has a username as ‘test’, and password as ‘test’. The
configuration procedure is as below:
Switch>en
Switch#config
Switch(Config)#web-user admin password 0 digital
1.1.2.3 Management via snmp network management software
To manage the switch with snmp, the following conditions should be met:

Switch Configuration SS2GR50i / SS2GR26i / SS2GR26ip

1) Switch has an IP address configured
2) As the client, the host IP address and the switch’s VLAN interface IP address is in the same
network segment.
3) If not 2), client can connect to an IP address of the switch via other devices, such as a
router.
4) Open the snmp function.
Management via snmp network management software, the host succeeds to ping an IP address of
the switch, then run the switch, snmp network management software will be found by SS2GR50i/26i
series, and operate it with read-write permission. For more detail please refer to the ‘Snmp Network
Management Software Usage Guide’.
1.2 CLI Interface
SS2GR50i/26i series switch provides three management interfaces: CLI(Command Line Interface),
Web interface and Snmp network management software.
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:
zConfiguration Modes
zConfiguration Syntax
zShortcut keys
zHelp function
zInput verification
zFuzzy match support
