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
SwitchModules in
slots 2, 3, and 4
DMM in
slot 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 CoreBuilder 5000
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 CoreBuilder 5000
SwitchModule User Guide.
■
Frame Tagging is disabled. For more information about
frame tagging, see Chapter 8 in the CoreBuilder 5000
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.
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: Although the DMM supports multiple
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.

For more information about IP configuration, see the
CoreBuilder 5000 SwitchModule User Guide on the
DocsOnCD documentation CD-ROM that comes with this
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.
LAN
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:
NMS
SwitchModules in
slots 2, 3, and 4
To manage the hub from the network management station
in the previous figure:
DMM in
slot 1
1 Configure IP settings for virtual bridge 1 using the
commands in the following example (values shown are
sample values):
LAN
> 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
Assigning an IP address to a virtual bridge automatically
enables the virtual bridge interface to the DMM.
NMS
2 Save the settings as follows:
Virtual bridge 1
Virtual bridge 2
> 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.
To create the configuration in this figure:
1 Enter the commands in the following example (values
shown are sample values):
> set bridge_port 3.1 vbridge 2
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.
> set bridge_port 3.2 vbridge 2
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:
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.
■
■
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.
> set bridge_port 4.all vbridge 2
2 Save the settings as follows:
> save all
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.

COREBUILDER® 5000 S WITCHMODULE Q UICK START AND REFERENCE
Enabling Communication Between
Virtual Bridges
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
CoreBuilder 5000 SwitchModule User Guide.
