Prior to accessing the switch from a Web browser, perform the following tasks:

— "Setting up the Web-based user interface" (page 18).

— If required, conﬁgure the switch with a valid IP address, subnet mask,

and default gateway. (Default: 192.168.1.128/255.255.255.0/0.0.0.0) See "Initial conﬁguration" (page 22).

— Set a new password by using the Web-based user interface.

Web-based user interface access is password controlled. (Default user name: nnadmin;default password : PlsChgMe!) See "Changing

the administrator password" (page 23).

ATTENTION

The Web pages of the Web-based user interface can load at different speeds depending on which Web browser you use.

ATTENTION

Web browser capabilities, such as page bookmarking, refresh, and page forward and page back, function as they would in any other Web site. However, these capabilities do not enhance the functionality of the Web-based user interface. Nortel recommends that you use only the navigation tools provided in the management interface.

Initial conﬁguration

Use this procedure to conﬁgure an IP address for the switch. To use the BES50 management features, you must ﬁrst conﬁgure the

BES50 with an IP address that is compatible with the network where it is being installed. For simplicity, conﬁgure the IP address before you permanently install the switch.

Procedure steps

Step Action 1

Place your switch close to the PC that you will use to conﬁgure it. It helps if you can see the front panel of the switch while you work on your PC.

Connect the Ethernet port of your PC to any port on the front panel of your switch.

Insert the power adapter into the DC power socket in front of the switch.

Plug the other end of the power adapter into a grounded, 3-pin socket, AC power source.

Check the front-panel LEDs as the device powers on to conﬁrm that the PWR LED is green. If not, check that the power cable is correctly plugged in.

If the PC IP address is different from the switch but is on the same subnet, go to the next step. (For example, if the PC and switch both have addresses that start with 192.168.1.x.) Otherwise, manually set the IP address for the PC. See "Changing a PC IP address"

(page 96).

The default IP address is 192.168.1.128, the default subnet mask is

255.255.255.0, and the default gateway is 0.0.0.0.

Open your Web browser and enter the address http://192.168.1.128. If you do not see the logon page, check your IP address and repeat step 3.

If you are using DHCP service, use the Element Manager to launch the BES50 Web-based user interface.

Enter the default user name nnadmin and default password PlsChgMe!, and click Login.

ATTENTION

If you are using DHCP service, skip the remaining steps.

(MIB) II object ID for the switch network management subsystem. System Up Time Length of time the management agent has been operational. System Contact Administrator responsible for the system. System Name Name assigned to the switch system. Location The system location.

Setting the IP address

You can use an IP address to manage access to the switch over your network. By default, the switch uses Dynamic Host Conﬁguration Protocol (DHCP) to assign IP settings to the management VLAN. (Default: VLAN

1.) If you want to manually conﬁgure IP settings, the IP address and subnet mask must be compatible with your network. You may also need to establish a default gateway between the switch and management stations that exist on another network segment.

You can manually conﬁgure a speciﬁc IP address or direct the device to obtain an address from a Bootstrap Protocol (BOOTP) or DHCP server. Valid IP addresses consist of four decimal numbers, 0 to 255, separated by periods. This is the only format that the Web-based user interface accepts.

Variable deﬁnitions

Variable Value

Management VLAN ID of the configured VLAN (Range: 1 to 4094).

This is the only VLAN through which you can gain management access to the switch. By default, all ports on the switch are members of VLAN 1, so a management station can be connected to any port on the switch. However, if other VLANs are configured and you change the management VLAN, you can lose management access to the switch. In this case, reconnect the management station to a port that is a member of the management VLAN.

IP Address Mode Select the configuration method.

If you select DHCP or BOOTP, the IP address does not function until a reply is received from the server. The switch periodically broadcasts a request for an IP address.

IP Address For Static IP Address Mode, enter the IP address of the

management access VLAN interface. Valid IP addresses consist of four numbers, 0 to 255, separated by periods. (Default: 192.168.1.128)

Subnet Mask For Static IP Address Mode, enter the host address bits used

for routing to specific subnets. (Default: 255.255.255.0)

Gateway IP address For Static IP Address Mode, enter the IP address of the

gateway router between this device and management stations

that exist on other network segments. (Default: 0.0.0.0) MAC Address The MAC address of this switch. Restart DHCP Requests a new IP address from the DHCP server.

Variable Value IP Configuration

Management VLAN ID of the configured Virtual Local Area Network (VLAN) (Range:

1 to 4094). This is the only VLAN through which you can gain management access to the switch. By default, all ports on the switch are members of VLAN 1, so a management station can be connected to any port on the switch. However, if other VLANs are configured and you change the management VLAN, you can lose management access to the switch. In this case, reconnect the management station to a port that is a member of the management VLAN.

IP Address Mode Select the configuration method.

If you select Dynamic Host Configuration Protocol (DHCP) or Bootstrap Protocol (BOOTP), the IP address does not function until a reply is received from the server. The switch periodically broadcasts a request for an IP address.

IP Address For Static IP Address Mode, enter the IP address of the

management access VLAN interface. Valid IP addresses consist of four numbers, 0 to 255, separated by periods. (Default: 192.168.1.128)

Subnet Mask For Static IP Address Mode, enter the host address bits used for

routing to specific subnets. (Default: 255.255.255.0)

Gateway IP address For Static IP Address Mode, enter the IP address of the gateway

router between this device and management stations that exist on other network segments. (Default: 0.0.0.0)

MAC Address The MAC address of this switch.

SNMP Community:

SNMP Community Capability The number of community strings supported by the BES50. Current List of currently configured community strings. Community String Type the name of the community string. The name acts like a

password and permits access to the SNMP protocol. Default strings: PlsChgMe!RO (read-only access), PlsChgMe!RW (read/write access). Range: 1 to 32 characters, case-sensitive.

Access Mode Select the access rights for the community string:

•

Read-Only—Authorized management stations can only retrieve Management Information Base (MIB) objects.

•

Read/Write—Authorized management stations can retrieve and modify MIB objects.

Trap Managers:

Trap Manager Capability The number of trap managers supported by the BES50. Current List of currently configured trap managers. Trap Manager IP Address Type the IP address of a new management station to receive

notification messages.

Trap Manager Community String

Specify a valid community string for the new trap manager entry. (Range: 1 to 32 characters, case-sensitive)

ATTENTION

Nortel recommends that you define this string in the SNMP

Configuratino page for version 1 or 2c clients, or define a

corresponding user name in the SNMPv3 Users page for

version 3 clients. Trap UDP Port The UDP port number used by the trap manager.

Trap Version Select the SNMP version. (Default: 1) Trap Security Level For trap version 3, specify one of the following security levels.

(Default: noAuthNoPriv)

•

noAuthNoPriv—SNMP communications do not use authentication or encryption.

•

AuthNoPriv—SNMP communications use authentication, but the data is not encrypted (only available for the SNMPv3 security model).

•

AuthPriv—SNMP communications use both authentication and encryption (only available for the SNMPv3 security model).

Trap Inform For version 2c and 3 hosts, notifications are sent as inform

messages. (Default: traps are used)

• Timeout—The number of seconds to wait for an acknowledgment before resending an inform message. (Range: 0 to 2147483647 centiseconds)

•

Retry times—The maximum number of times to resend an inform message if the recipient does not acknowledge receipt. (Range: 0 to 255)
