Cabletron Systems 1200 Switch User Manual


 
EXAMPLE NETWORKS
54 CyberSWITCH
The interface name is a symbolic name given to the interface. For the WAN (RLAN) interface, you
should use a name that describes this interface. Type Satellites for this example.
You will then be asked for the IP address for the interface. In our example, the value you should
enter is 198.12.10.1. You will then be asked for the IP subnet mask value. In our example, we are
using a Class C address (without any subnetwork addressing) that requires 24 bits of the address
to define the network number. Therefore, press <return> to accept the default of “24” significant
bits. Press <return> to accept the default packet encapsulation type (Ethernet). Press <return> to
accept the default of 1500 as the MTU size. Press <return> to accept the default transmit broadcast
address.
The rest of the RLAN interface information requested pertains to the Proxy ARP and, if you have
not disabled RIP, the RIP feature. Accept all of the default values, or modify as needed.
The following screen will summarize the configured interfaces:

CONFIGURING THE SECURITY
This example has two remote devices, and the device information for each of those devices must be
configured. Device security is used, and the remote devices are configured in the on-node
authentication database. Device security using an on-node authentication database are the default
values.
Before beginning, note the following:
This is a system configuration using IP Routing and Bridge MAC Address Security. We will disable
IP routing so that the system will recognize particular devices as a remote bridges. When
configuring device-level bridging information for each remote bridge, we will provide the
following elements: Device Name, Device Type, Bridge Ethernet Address and associated
password, and the IP (Sub-) Network Number of the remote LAN.
Note that there may be multiple remote bridges and LAN segments on the subnetwork 198.12.10.0.
(Our example includes two.) When using the RLAN interface, you are only required to enter the
subnetwork address of the IP network when configuring each device. In this example, the host at
Carmel is 198.12.10.2, and the host at Monterey is 198.12.10.3; but when configuring each device
(i.e., bridge) you only enter the IP subnetwork number 198.12.10.0.
To begin the security configuration, press 3 at CFGEDIT’s Main Menu. The Security Configuration
Menu will then be displayed. The sections below provide instructions for configuring security
information.
