Configuring Business Policy Switches with Optivity Quick2Config

Chapter 1 Configuring switch es

You can use Optivity Qu ick2Config 2.2 to view and modify conf igura tion da ta for Nortel Networks Business Policy Switch 2000 and BayStack 450, 410, and 350 Series switches.

Read this chapter for information about how to start working with configuration data, and instructions for setting or changing the properties of default switch configuration objects.

Configuring Business Policy Switches with Optivity Quick2Config

22 Chapter 1 Configuring switches

Prerequisites

Before you can use Optivity Quick2Config 2.2 to configure a Business Policy Switch 2000 or BayStack switch, the switch must be:

• Accessible to t he Op tivity configuration serv er through an estab li she d Si mple Network Management Protocol (SNMP) connection.

For the initial setup of a switch, you configure an IP address, subnet mask, and gateway address for the switch or stack. For a standalone switch, you enter the in-band IP address. For a stack configuration, you enter the stack IP address. For detailed information about setting up the initial network connection, see the documentation that came with your switch.

Note:

• Visible in the Quick2Config Configuration Data folder. You can import existing configurations to the Quick2Config database, or you

can create configurations off-line. For information about importing existing configuration data, see “Importing configurations,” next. For information about adding configuration data manually, see “Creating switch

configurations” on page 23.

The default management virtual LAN (VLAN) is VLAN 1.

Importing conf igu ratio ns

You can import existing con figuration data from the Business Policy Switch 2000 and BayStack 450 devices in your network to the Quick2Config database.

Business Policy Switch 2000 devices use SNMP to transfer configuration data; they do not support Trivial File Transfer Protocol (TFTP).

Note:

File menu is not disabled, this option does not work for Business Policy Switch 2000 and BayStack switches.

Although the Import > From TFTP option on the Quick2Config

311208-A Rev 00

For import procedures, see Using the Optivity Quick2Config 2.2 Client Software.

Before you attempt to import data from a switch, make sure that the switch SNMP agent is available, and that you can supply the device IP address and community string.

Quick2Config init ially determines system information from the switch. After you import a configuration to the Quick2Config database, you do not have to modify any system data unless you want to change something in the existing configuration.

Creating switch configurations

You can use the Configuration Data Palette to create new standalone switch and stack configurations.

The Palette lists templates by product group (Figure 1).

Configuring Business Policy Switches with Optivity Quick2Config

24 Chapter 1 Configuring switches

When you create standal one and st ack templa tes, Quick 2Conf ig cr eates def ault IP, MLT, SNMP, STP, and QoS (Business Policy Switch 2000 only) configuration objects in the navigation pane tree. Standalone switches also automatically include configuration objects for switch ports and a default port-based VLAN.

Note:

them from th e Palette.

To match the actual configuration of the device you are creating, you can use the Palette to add the following configuration objects to a standalone or stack system:

• 1 to 8 stack units (each in cl udes swit ch port s and a def aul t, port-b ased VLAN)

• Media-dependent adapter (MDA) hardware

• VLANs

• Internet Gateway Management Protocol (IGMP)

You cannot delete these default configuration objects, or create

Adding or changing system information

This section describes how to use Quick2Config to initially configure a switch that you created from the Configuration Data Palette, or to modify the imported system information for a managed switch.

Note:

in an imported configuration.

In most cases, you do not have to modify the system information

311208-A Rev 00

You can configure several system properties:

• To set or change the system name, contact, or location information, see

“Configuring basic properties,” next.

• To enable or disable Ethernet switch and MD A ports , or to conf i gure Eth ernet

line speed, see “Configuring Ether net ports” on page 26.

• To enable or disable ATM switch and MDA ports on a BayStack swit ch, or to configure the p ort ATM properties , see “Configuring ATM MDA ports

(BayStack 450 only)” on page 27.

Chapter 1 Configuring switches 25

• To set or change the switch IP address or subnet mask, see “Configuring IP”

on page 30.

• To supply the required SNMP community strings or to enable SNMP traps, see “Configuring SNMP” on page 31.

Configuring basic properties

When you import a switch, some general system information is added to the database. You can view or configure the system name, contact, and location strings for a switch.

To modify the basic system properties for a switch:

In the navigation pane, select the switch.

In the context-sensitive pane, click the Properties tab.

Click the Basic tab (Figure 2).

Figure 2 Basic tab system properties

In the System Contact, System Location, and System Name fields, enter ASCII strings to identify the switch.

Each string can be up to 56 characters.

Quick2Config queries the system management information base (MIB) to report the hardware, firmware, and software versions running on the switch, and the length of time since the last reset. You cannot edit these fields.

Configuring Business Policy Switches with Optivity Quick2Config

26 Chapter 1 Configuring switches

Configuring Ethernet ports

You can use Quick2Config to enable or disable switch and MDA ports, and to set the port speed for an Ethernet port.

To set basic Ethernet port properties:

In the navi gati on pane , open t he swit ch or Eth ernet MDA and select a port. To assign the same properties to a group of ports on the same switch, select multiple ports in the navigation pane.

The port Basic tab opens in the context-sensitive pane (Figure 3).

Figure 3 Basic port properties

311208-A Rev 00

The Operational Status field indicates the current link state of the port, as follows:

• Up indicates that the port is connected and operational.

• Down indicates that the port is not connected or is not operational.

The field is blank when you ar e working offl i ne to cre ate a new configurat i on.

From the Administration Status list, choose Enabled or Disabled to force the link up or down.

From the Port speed list, choose the Ethernet line speed and duplex mode combinations for the selected port; or, choose Autonegotiate to configure the port to match the best service provided by the connected station, up to 100 Mb/s Full Duplex.

Valid options depend on the MDA hardware. Fiber optic links do not use autonegotiation.

Chapter 1 Configuring switches 27

Full duplex operation is intended for directly connected links, such as between two switches or between a switch and an end station. Half duplex operation, where transmission occurs in one direction at a time, is usually the best choice for share d links that re quire ac cess contr ol and collisi on detecti on.

Note the foll owing:

• You can set gigabit MDA ports to Autonegotiate or 1000 Mb/s Full

Duplex only.

• Business Polic y Switch 2000 fiber optic ports sup port onl y 100 Mb/s Full

Duplex.

• BayStack 450 fiber optic ports support 100 Mb/s Half Duplex or

100 Mb/s Full Duplex.

You can also set the following additional properties at the port level:

• VLAN port properties — see “Configuring VLAN ports” on page 42

• Spanning tree protocol (STP) port properties — see “Configuring spanning

tree” on page 55

• Internet Group Management Protocol (IGMP) static router port property — see “Creating static router ports” on page 49

Configuring ATM MDA ports (BayStack 450 only)

On BayStack 450 switches running agent version 3.1 or later, you can use Quick2Config to configure the ATM ports on 2M3 and 2S3 MDA modules to participate in an emulated LAN (ELAN).

Using ATM Forum LAN emulation (LANE), the BayStack 450 switch can communicate transparently with ATM servers and other LAN clients. As LAN emulation clients (LECs), the MDA ports perform data forwarding, address resolution, and ATM control functions. A LAN Emulation server (LES) in the network provides MAC-to-ATM address translation for the LECs.

Configuring Business Policy Switches with Optivity Quick2Config

28 Chapter 1 Configuring switches

This section describes how to use the Basic properties tab to enable or disable ATM ports, set the port speed, enable or disable the LEC software, and to configure LEC failover.

To view or set basic ATM port properties:

In the navigation pane, open the MDA and select a port (Figure 4).

Figure 4 ATM MDA ports

To assign the same properties to a group of ports, select multiple ports in the navigation pane.

The port Basic tab opens in the context-sensitive pane (Figure 5).

Figure 5 ATM port properties

311208-A Rev 00

Chapter 1 Configuring switches 29

The Operational Status property indicates the current link state of the port, as follows:

• Up indicates that the port is connected and operational.

• Down indicates that the port is not connected or is not operational.

The LEC State field indicates whether the LAN emulation client is currently active.

From the Administration Status list, choose Enabled.

From the Port speed list, choose a line speed and duple x mode for the selected port, or choose Autonegotiate to match the best service available.

In the ELAN Name field, type the name of the ELAN.

To configure LEC Failover, see “Configuring LEC failover,” next.

You can also set VLAN and STP properties for each ATM port. For information, see:

• “Configuring VLAN ports” on page 42

• “Configuring spanning tree” on page 55

Configuring LEC failover

LEC Failover allows ELAN traffic to move from a failing port to another available port. A unique ATM address identifies each LEC, which the LANE protocol associates with one or more port MAC addresses, or LEC instances.

To configure LEC fail over:

From the LEC Status list, choose Disabled. You must disable the LEC before you can modify the failover properties.

From the Actual Ph ysica l Port lis t, cho ose A1 or A2 to id entif y the port that is currently carrying traffic.

From the Desired Physical Port list, choose the alternate port to use in a failover.

For example, if the Actual Physical Port is A1, choose A2.

From the LEC Fail Over list, choose Enabled.
