Bridged Ethernet operation

Model 6081RC Network Access Server Getting Started Guide
8 • Configuring for bridged
Basic assumptions
The bridged Ethernet network described in section
“Bridged Ethernet operation”
on page 62 is based on the
following basic assumptions:
•
Concerning the Ethernet interface:
-
You will connect a management workstation (such as a PC) to the 6081RC front panel Ethernet interface.
-
You will use the management workstation on the front panel Ethernet interface to configure the 6081RC
using a web browser.
•
Your workstation must reside within the same IP subnetwork as the 6081RC Ethernet interface in order to
connect to the 6081RC management interface via the factory-default IP address, which is 198.168.200.98.
In other words, the first three octets of your workstation’s IP address must be 198.168.200.
•
Once the 6081RC has been configured for operation, you may wish to connect the front Ethernet port to
the LAN. Doing so offers the following advantages:
-
Remote management—You can log in to the 6081RC’s management interface remotely using any work-
station connected to the LAN and standard http browser.
-
Multiple operators—Two or more operators can manage the 6081RC, at the same time or at different
times, using multiple workstations on the LAN.
•
Before moving the Ethernet Port to the LAN, you must first assign an IP address that has the same network
number as the LAN. For further instructions, see section
“IP address configuration”
on page 42.
Defaults settings
The bridged Ethernet configuration described in section “
“Basic assumptions”
operates using the 6081RC’s
factory default values for all configurable parameters. The 6081RC’s factory default parameter values are
described below:
•
Ethernet Interface A— By factory default the IP address assigned to Ethernet Interface A is
192.168.200.98/24 (The designation /24 indicates the IP address has a netmask of 255.255.255.0).
•
Ethernet Interface B — By factory default Ethernet Interface B is not assigned an IP address. Because the
interface is intended to handle bridged traffic only, no IP address is needed.
•
Ethernet Interface C— By factory default Ethernet Interface B is not assigned an IP address.
CPE configuration
The Patton Model 3201 Router Modems used in the Bridged Ethernet network in section
“Bridged Ethernet
operation”
on page 62 are factory-configured in customer premise (CP) mode—as opposed to central office
(CO) mode. If any Model 3201 used in this network has been changed to CO mode, you must re-configure
the device for CP mode.
Note
For information on configuring the Model 3201, refer to the Model
3201 Getting Started Guide or Administrator’s Reference Guide that
came with the device.
