8.0 Basic Configuration Steps

The following figure shows the default configuration with three SwitchModules installed in the hub:

This section uses network configuration examples to introduce important concepts about implementing CoreBuilder 5000 SwitchModules in your network. Your network configuration may be more or less complex than the network configuration examples that are shown here.

8.1 Default Configuration After Installation

After you install one or more SwitchModule into the CoreBuilder 5000 hub, the default configuration is as follows:

■ All SwitchModule ports are assigned to virtual bridge 1.

This assignment means that all SwitchModule ports can communicate with all other SwitchModule ports, regardless of the slot in which they reside, and subject to the slot restrictions that are described in Section 3.2, step 4.

■ All SwitchModule ports are automatically connected to

the switching backplane in the hub (either PacketChannel or PacketChannel with Cell-Switching). You do not need to enter a command to assign ports to the backplane, as other CoreBuilder 5000 media modules may require.

■ Ethernet Backplane SwitchModule backplane ports

(ports 17 through 24) are permanently connected to shared Ethernet backplanes 1 through 8.

■ All SwitchModule ports (except Ethernet Backplane

SwitchModule backplane ports 17 through 24) are enabled and capable of switching traffic if you attach devices to the ports. You must enable Ethernet Backplane SwitchModule ports 17 through 24 using the DMM command SET BPORT_MAU MODE ENABLE or SET PORT MODE ENABLE. For information about the special port numbering system that applies to these ports, see Chapter 4 in the

SwitchModule User Guide

■ The Spanning Tree Protocol is enabled on virtual

bridge 1 and on all SwitchModule ports. Spanning Tree parameters are set to their default settings, which are described in Chapter 7 in the

SwitchModule User Guide

■ Frame Tagging is disabled. For more information about

frame tagging, see Chapter 8 in the

SwitchModule User Guide

■ The maximum vbridge value is set to 32, which means

that you can assign ports to virtual bridges 1 through

32. To change this value, see Chapter 2 in the

CoreBuilder 5000 SwitchModule User Guide

CoreBuilder 5000

SwitchModules in slots 2, 3, and 4

DMM in

slot 1

Virtual bridge 1

8.2 Enabling SNMP Management Through the SwitchModule

Configure IP settings for a virtual bridge only if the DMM has no other means of IP connectivity.

For example, you do not need to configure IP settings if the hub contains an Ethernet media module with a network monitor card (NMC) attached to it. The NMC provides connectivity between SwitchModules and the DMM.

If you do not already have an in-band connection to the DMM, and you want to manage the hub from a network management station (NMS) that is connected to a SwitchModule port, use the instructions in this section.

CAUTION:

IP addresses, enable the interface for only one address per subnet (on the network that is attached to your default gateway). Enabling multiple IP interfaces on the same subnet may cause connectivity problems.

When a model A SwitchModule (the model number ends in -A) is installed in the hub, include at least one of its ports in the virtual bridge that is acting as the IP relay interface. For example, if there are five virtual bridges, and if you are managing the hub through virtual bridge 1, ensure that virtual bridge 1 includes at least one of the model A SwitchModule’s ports.

Although the DMM supports multiple

To manage the hub from the network management station in the previous figure:

Configure IP settings for virtual bridge 1 using the

commands in the following example (values shown are sample values):

> set ip subnet_mask ff.ff.ff.00 vbridge 1 > set ip ip_address 141.102.3.131 vbridge 1

set ip default_gateway 141.102.3.2 vbridge 1

For more information about IP configuration, see the

documentation CD-ROM that comes with this

on the

product.

8.3 Creating an Additional Virtual Bridge

A virtual bridge is a user-defined group of SwitchModule ports. This group of ports operates as a single logical bridge.

You can segment your network into more than one virtual bridge by creating new virtual bridges. You can assign any port on any SwitchModule to the new virtual bridge.

The following figure shows a SwitchModule network that is configured with two virtual bridges:

SwitchModules in slots 2, 3, and 4

DMM in slot 1

LAN

Assigning an IP address to a virtual bridge automatically enables the virtual bridge interface to the DMM.

Save the settings as follows:

> save ip

You can now access the DMM from the network management station. You can also send SNMP and RMON requests to the DMM. From the DMM, you can manage any network, virtual bridge, or module in the CoreBuilder 5000 hub.

If you have multiple subnetworks in your network, and you want to manage the hub in-band from each subnetwork, you must configure IP settings for each subnetwork.

If you already have an in-band connection to the DMM and if you still want to add in-band connectivity through a SwitchModule port, do one of the following:

■ Before you establish an in-band DMM interface through

the SwitchModule, assign the virtual bridge an IP address that is on a unique subnetwork.

■ Disable the existing in-band DMM interface.

NMS

Virtual bridge 1 Virtual bridge 2

To create the configuration in this figure:

Enter the commands in the following example (values

shown are sample values):

> set bridge_port 3.1 vbridge 2 > set bridge_port 3.2 vbridge 2 > set bridge_port 4.all vbridge 2

Save the settings as follows:

> save all

The new network configuration consists of two separate virtual bridges. Each virtual bridge maintains a separate Spanning Tree configuration. All ports on virtual bridge 2 are enabled by default.

The two virtual bridges that are described in this example cannot send traffic to one another at this point without an external connection. (See Section 8.4.) However, you can manage all ports on both virtual bridges using the DMM or other supported network management software, such as 3Com Transcend

Network Control Services.

8.4 Enabling Communication Between Virtual Bridges

9.0 Finding More Information

You can enable communication between virtual bridges by connecting ports on different virtual bridges through a front panel, through other physical connections (such as a router), crossover cables, or, if an Ethernet Backplane SwitchModule is installed in the hub, between virtual bridges over the CoreBuilder 5000 shared Ethernet backplane. For more information, see the
