Edge Router Module Features

1-7

Top ology Switching Using topology switching you can:

■

Switch the ONline Edge Router module among any of three Ethernet

networks (channels) on the hub backplane

■

Switch the ONcore Edge Router module among any of eight Ethernet

networks (channels) on the hub backplane

You perform topology switching using:

■

Network management module commands

Simple Network Management Protocol (SNMP)

You do not have to swap cables or move the Edge Router module to move

the routing or bridging functions to a different network within an ONline or

ONcore hub. You can enter a command through one of the 3Com

management modules and the network change is made automatically.

Network Reliability The Edge Router module lets you implement several levels of reliability in

your network as follows:

■

By routing the Edge Router module’s serial and auxiliary ports in parallel,

you can create up to three redundant links.

If the primary link fails, you can have up to two backup links in place to

ensure application availability.

These links can also implement load-balancing to enhance network

performance. An example of a reliable network configuration is shown in

Figure 1-3.

CHAPTER 3: CONFIGURING THE EDGE ROUTER MODULE

Carrier NVRAM Settings

The ONcore carrier can store configuration settings in its NVRAM

(non-volatile random access memory), which it can use when powering on

in either a managed or unmanaged hub. Two NVRAM DIP switches control

whether or not the carrier uses NVRAM settings. For information on setting

the NVRAM DIP switches, refer to Enabling or Disabling NVRAM

Configuration on page 2-10.

When the ONcore carrier ships from the factory, the NVRAM does not

contain any configuration settings.

The carrier stores configuration settings in NVRAM when either of the

following occurs:

■

You use a DMM configuration command or an SNMP manager to change a

carrier configuration setting. For example, if you use the SET PORT

NETWORK command to change a carrier port network assignment, the

carrier stores the new network assignment in its NVRAM.

The carrier stores the new setting as soon as you issue the command. The

SAVE command does not affect the contents of NVRAM.

■

The DMM sends configuration settings to the carrier during a hot swap. For

a definition of hot swap, refer to Hot Swapping an ONcore Module on

page 3-7.

Carrier DIP Switch Settings

The carrier contains a DIP switch that you can use to configure network

assignments. For more information on DIP switch settings, refer to

Configuring the ONcore Carrier DIP Switches on page 2-9.

Carrier Default Settings

In some cases, the carrier uses default configuration settings contained in its

software. The default network assignment for the ONcore carrier is Isolate_1.

swap. Whether or not you hot swap the Edge Router module affects which

configuration source the carrier uses.

When you perform a hot swap, the DMM transfers to the new carrier the

configuration used by the old carrier. The new carrier saves the settings in

its NVRAM.

The DMM transfers the configuration to the new carrier only if it has a saved

configuration for the old carrier installed in that slot. The DMM saves the

configuration when you perform one of the following:

■

Issue the SAVE command.

Use SNMP to make the configuration changes to the carrier. The DMM

automatically saves the changes.

■

Reset or power-cycle the DMM. The DMM automatically acquires and saves

the NVRAM configurations of all installed modules.

Swapping in a new carrier that contains a different engine from the old

carrier is still a hot swap. Only the carrier models must be the same.

* Use the SHOW DEVICE command to view the DIP configuration setting. Use the SET DEVICE

DIP_CONFIGURATION command to change the DIP configuration setting.

† If the carrier does not have configuration settings stored in NVRAM, it uses default settings.

If the DMM detects a problem with the NVRAM configuration, it forces the carrier to use

default settings. For example, if you install the carrier with ports assigned to Ethernet_8 into an

ONcore hub model that does not support Ethernet_8. If the configuration problem is port

level, the DMM forces only the affected ports to use default settings.

‡ The DMM must be fully initialized when you install the carrier module.

Selecting a Network The Edge Router engine connects to an Ethernet network through a

backplane port on the ONcore carrier. A base engine installed in ONcore

carrier engine bay 1 uses carrier backplane port 1. A base engine installed in

ONcore carrier engine bay 2 uses carrier backplane port 5.

You can assign a carrier backplane port to:

■

One of eight Ethernet backplane networks

One of four Isolated backplane networks

For details on backplane networks, refer to the ONcore Switching Hub

Installation and Operation Guide (Document Number 17-00362-5).

3-9

To assign a carrier backplane port to a network using network management

software, use the following command:

set port slot.port network {ethernet_1 ... ethernet_8}

{isolated_1 ... isolated_4}

For example, the following command sets backplane port 1 (engine 1) in

the carrier installed in slot 3 to Ethernet_2:

ONcore> set port 3.1 network ethernet_2

Port 03.01 network id set to ETHERNET_2
