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).

Changing the administrator password 23

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.

From the main menu, click Conﬁguration > IP.

10 On the IP Conﬁguration page, enter the new IP address, subnet

mask and gateway IP address.

Click Submit.

—End—

No other conﬁguration changes are required at this stage, but Nortel recommends that you change the administrator password before you log off.

Changing the administrator password

Use the User Accounts page to change the switch access passwords.

Procedure steps

Step Action 1

From the main menu, choose Administration > Security > User Accounts.

In the Change Password table, enter the user name for the account whose password you want to change.

Type in the new password and retype the new password in the

Conﬁrm Password ﬁeld.

Click Change Password.

Variable Value

System Description Description of the switch. System Object ID This read-only parameter is the Management Information Base

(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.

Conﬁguring port security

Use the Port Security page to conﬁgure secure addresses for individual ports.

Using the port security feature, you can conﬁgure a switch port with one or more device MAC addresses authorized to access the network through that port.

To use port security, specify a maximum number of addresses to allow on the port and then let the switch dynamically learn the source pair—MAC address, VLAN—for frames received on the port. See "Conﬁguring 802.1X

port settings" (page 88). You can also manually add secure addresses to the

port by using the Static Address table. See "Setting static addresses" (page

85). When the port reaches the maximum number of MAC addresses, the

selected port stops learning. The MAC addresses already in the address table are retained and do not age out. Any other device that attempts to use the port is prevented from accessing the switch.

A secure port:

•

cannot use port monitoring

•

cannot be a multi-VLAN port

•

cannot be used as a member of a static or dynamic trunk

•

should not be connected to a network interconnection device

as the Element Manager. You can specify up to ﬁve management stations to receive authentication failure messages and other notiﬁcation messages from the switch.

By default, the switch issues notiﬁcations as trap messages. The recipient of a trap message does not send a response to the switch. Therefore, traps are not reliable as inform messages, which include a request for acknowledgement of receipt. Informs can be used to ensure that the host receives critical information. However, inform messages consume more system resources because they must be kept in memory until a response is received. Inform messages also add to network trafﬁc.

If you specify an SNMP version 3 host, then the Trap Manager Community String is interpreted as an SNMP user name. If you use SNMP version 3 authentication or encryption options (authNoPriv or authPriv), you must ﬁrst deﬁne the user name in the SNMP version 3 Users page to enable password authentication and SNMP access to the switch. However, if you specify a SNMP version 3 host with the no authentication (noAuth) option, an SNMP user account is automatically generated, and the switch authorizes SNMP access for the host.

Prerequisites

Setting a remote engine ID

Use the Remove Engine ID page to set the SNMP version 3 engine ID for a remote device.

To send inform messages to an SNMP version 3 user on a remote device, you must ﬁrst specify the engine identiﬁer for the SNMP agent on the remote device where the user resides. The remote engine ID is used to compute the security digest for authenticating and encrypting packets sent to a user on the remote host.

SNMP passwords are localized by using the engine ID of the authoritative agent. For inform messages, the authoritative SNMP agent is the remote agent. You therefore need to conﬁgure the remote agent SNMP engine ID before you can send proxy requests or inform messages to it.

Prerequisites

Creating trunk groups 57

Prerequisites

•

Before you make any physical connections between devices, use the Web-based user interface to specify the trunk on the devices at both ends.

•

To avoid creating loops, conﬁgure the port trunks completely before you connect the corresponding network cables between switches.

•

Conﬁgure the ports at both ends of a connection as trunk ports.

•

Ensure that static trunks on switches of different types are compatible with the IEEE802.3ad link aggregation standard.

•

Conﬁgure the ports at both ends of a trunk in an identical manner, including communication mode (speed, duplex mode, and ﬂow control), Virtual Local Area Network (VLAN) assignments, and Class Of Service (CoS) settings.

•

Ensure that all trunk ports have the same media type (for example, all 100BASE-T or all 1000BASE-TX).

• Treat all the portsin a trunk as a whole when moving, adding, or deleting them to or from a VLAN.

Conﬁguring a static trunk

Use this procedure to conﬁgure static trunks. You can create up to six trunks on the switch, with up to four ports for each trunk.

When you conﬁgure static trunks, keep in mind the following:

•

You may not be able to link switches of different types, depending on the manufacturer’s implementation.

• Spanning Tree Algorithm (STA), VLAN, and IGMP settings can only be conﬁgured for the entire trunk.

•

Static trunks on the BES50 are IEEE802.3ad link aggregationcompatible.

Prerequisites

•

To avoid creating a loop in the network: — Add a static trunk through the conﬁguration interface before you

connect the ports.

— Disconnect the ports before you remove a static trunk through the

conﬁguration interface.

Enabling LACP on selected ports

Use the LACP Conﬁguration page to select ports for dynamic LACP. Keep the following points in mind when you select ports for LACP conﬁguration:

•

To avoid creating a loop in the network, enable LACP before you connect the ports, and disconnect the ports before you disable LACP.

•

After LACP is enabled on the connected ports, the trunk is activated automatically.

•

A trunk formed with another switch by using LACP is automatically assigned to the next available trunk ID.

•

If more than four ports attached to the same target switch are LACP-enabled, the additional ports are placed in standby mode and are enabled only if one of the active links fails.

•

All ports on both ends of an LACP trunk must be conﬁgured for full duplex, either by forced mode or autonegotiation.

• Trunks dynamically established through LACP are shown in the Member List on the Trunk Membership listing.

Setting the switch power budget

Use this procedure to deﬁne the Power over Ethernet (PoE) power budget for the switch.

You can deﬁne a maximum PoE power budget for the switch (power available to all switch ports) so that power can be centrally managed, preventing overload conditions at the power source. If the power demand from devices connected to the switch exceeds the power budget setting, the switch uses port power priority settings to limit the supplied power.

Procedure steps

Step Action 1

From the main menu, choose Conﬁguration > PoE > Power Conﬁguration.

Type the desired power allocation.

ATTENTION

Nortel recommends that you leave this value at the default setting of 84 watts.

Variable Value

Priority Type the bridge priority used in selecting the root device, root port,

and designated port. The device with the highest priority becomes the STA root device. However, if all devices have the same priority, the device with the lowest MAC address becomes the root device. Lower numeric values indicate higher priority. (Default: 32 768. Range: 0 to 61 440 in increments of 1 for 802.1D format, or increments of 4 096 for 802.1t format. Options for 802.1t format: 0, 4 096, 8 192, 12 288, 16 384, 20 480, 24 576, 28 672, 32 768, 36 864, 40 960, 45 056, 49 152, 53 248, 57 344, 61 440)

When the Switch Becomes Root

Hello Time Type the interval (in seconds) at which this device transmits a

configuration message. (Default: 2. Minimum: 1. Maximum: The lower of 10 or [{Max. Message Age / 2} -1])

Maximum Age Type the maximum time (in seconds) a device can wait

without receiving a configuration message before attempting to reconfigure. All device ports (except for designated ports) should receive configuration messages at regular intervals. Any port that ages out STA information (provided in the last configuration message) becomes the designated port for the attached Local Area Network (LAN). If it is a root port, a new root port is selected from among the device ports attached to the network. (In this instance, the term

ports refers to both ports and trunks.) (Default:

20. Minimum: The higher of 6 or [2 x {Hello Time + 1}]. Maximum: The lower of 40 or [2 x {Forward Delay—1}])

Forward Delay Type the maximum time (in seconds) the device waits before

changing states. (For example, changing from discarding to learning to forwarding). Every device must receive information about topology changes before it starts to forward frames. In addition, each port needs time to listen for conflicting information that can cause it to return to a discarding state resulting in temporary data loops. (Default: 15. Minimum: The higher of 4 or [{Max. Message Age / 2} + 1]. Maximum: 30)

Advanced

Path Cost Method Select the best path between devices. (Default: Long)

This option determines the range of values that can be assigned to each interface:

•

Long: Specifies 32-bit based values ranging from 1 to 200 000 000.

•

Short: Specifies 16-bit based values ranging from 1 to 65 535.

Transmission Limit Type the minimum interval between the transmission of

consecutive protocol messages. This is the maximum transmission rate for Bridge Protocol Data Units (BPDUs). (Range: 1 to 10. Default: 3.)

Variable Value

Priority Type the priority to use for this port in the Spanning Tree Protocol.

If the path cost for all ports on a switch is the same, the port with the highest priority (lowest value) is configured as an active link in the Spanning Tree Protocol. This makes a port with higher priority less likely to be blocked if the Spanning Tree Protocol detects network loops. Where more than one port is assigned the highest priority, the port with lowest numeric identifier is enabled. (Default:

128. Range: 0 to 240, in increments of 16.)

Admin Path Cost Type the value to establish the best path between devices. Assign

lower values to ports attached to faster media, and assign higher values to ports with slower media. Path cost takes precedence over port priority. When the Path Cost Method is set to short, the maximum path cost is 65 535. Ranges:

•

Admin Edge Port (Fast Forwarding)

If the interface is connected to an end-node device, or to a LAN segment that is at the end of a bridged LAN, select to enable. Because end nodes cannot cause forwarding loops, they can pass directly through to the spanning tree forwarding state. Specifying edge ports provides quicker convergence for devices such as workstations or servers, retains the current forwarding database to reduce the amount of frame flooding required to rebuild address tables during reconfiguration events, does not cause the spanning tree to initiate reconfiguration when the interface changes state, and also overcomes other STA-related timeout problems.

Assigning ports to VLANs

Before you enable VLANs for the switch, you must ﬁrst assign each port to the VLAN groups in which it will participate. By default, all ports are assigned to VLAN 1 as untagged ports.

Add a port as a tagged port if you want the port to carry trafﬁc for one or more VLANs, and for any intermediate network devices, or for the host at the other end of the connection support VLANs. Assign ports on the other VLAN-aware network devices along the path to carry this trafﬁc to the same VLANs, either manually or dynamically by using Generic VLAN Registration Protocol (GVRP).

Add a port as an untagged port if you want the port to participate in one or more VLANs, but not on the intermediate network devices nor on the host at the other end of the connection support VLANs.

You can assign ports to:

•

multiple tagged VLANs on the BES50FE-12/24T and the BES50GE12/24T

• multiple untagged VLANs on the BES50FE-12/24T

•

only one untagged VLAN on the BES50GE12/24T

For BES50GE-12/24T, if a port is an untagged member of VLAN 1, making it an untagged member of VLAN 2 disassociates it from VLAN 1. The same result occurs from VLAN 2 to VLAN 1.

ATTENTION

VLAN-tagged frames can pass through VLAN-aware or VLAN-unaware network interconnection devices, but the VLAN tags should be stripped off before passing the VLAN-tagged frames on to any end-node host that does not support VLAN tagging.

PVID Type the VLAN ID assigned to untagged frames received on the

interface.

If an interface is not a member of VLAN 1 and you assign its PVID

to this VLAN, the interface is automatically added to VLAN 1 as

an untagged member. For all other VLANs, an interface must first

be configured as an untagged member before you can assign its

PVID to that group. (Default: 1) Acceptable Frame Type Select frame types accepted by the interface. When set to receive

all frame types, any untagged frames are assigned to the default

VLAN. (Option: All, Tagged; Default: All) Ingress Filtering Determines how to process frames tagged for VLANs for which

the ingress port is not a member:

•

Ingress filtering only affects tagged frames.

•

Ingress filtering does not affect VLAN independent BPDU frames, such as GVRP or STA. However, ingress filtering does affect VLAN dependent BPDU frames, such as GMRP.

Select to enable ingress filtering and to direct ports to discard

frames tagged for VLANs for which they are not a member. If

ingress filtering is disabled, frames tagged for VLANs for which

they are not a member are flooded to all other ports, except for

those VLANs explicitly forbidden on this port. (Default: Disabled) GVRP Status Select to enable GVRP for the interface. GVRP must be globally

enabled for the switch before this setting can take effect. When

disabled, any GVRP packets received on this port are discarded

and no GVRP registrations are propagated from other ports.

(Default: Disabled) GARP Join Timer Type the interval between transmitting requests and queries to

participate in a VLAN group. (Range: 20 to 1 000 centiseconds.

Default: 20) GARP Leave Timer Type the interval a port waits before leaving a VLAN group. Set

this time to more than twice the join time, to ensure that the

applicants can rejoin before the port actually leaves the group

after a Leave or LeaveAll message is issued. (Range: 60 to 3 000

centiseconds. Default: 60) GARP LeaveAll Timer Type the interval between sending out a LeaveAll query message

for VLAN group participants and the port leaving the group. Set

this interval to be considerably larger than the Leave Timer to

minimize the amount of traffic generated by nodes rejoining the

group. (Range: 500 to 18 000 centiseconds. Default: 1 000)
