Model 6081RC Network Access Server Getting Started Guide
4 • Configuring Ethernet ports
Introduction
The model 6081RC comes equipped with three 10/100Base-T Ethernet ports—one externally accessible and
two connected to the PICMG 2.16 backplane (with options for PMC Ethernet cards to route backplane inter-
faces to the front panel).
This chapter describes:
•
Configuring the Ethernet interfaces (see section
“Ethernet interface configuration”
for details)
•
Configuring IP addresses for the Ethernet interfaces (see section
“IP address configuration”
on page 42
for details)
Ethernet interface configuration
The Model 6081RC EdgeRoute Module provides three Ethernet ports, A, B and C. The EdgeRoute presents
Ethernet port A on a front panel RJ-45 connector. Ethernet ports B and C are presented on the Model 6081’s
rear connector which connects to the packet switched bus (PSB) Ethernet bus within the chassis mid-plane.
When the optional Fast-Ethernet Transition Module (rear-card, part number 6081TM/FENET/2/TX) is
installed in the chassis behind the Model 6081, Ethernet ports B and C will also be presented on the rear-panel
RJ-45 ports. However, conflicts can occur if traffic is routed to an Ethernet port from both the midplane bus
and a rear-panel connector simultaneously.
Optional Fast-Ethernet PMC Module for the 6081RC Front Module
Your EdgeRoute module may be shipped with a Fast-Ethernet PMC Module (part number
PEC1/FENET/2/TX) factory installed in PMC slot 2. You may also purchase the Fast-Ethernet PMC Module
separately for installation in the field (see section
“Installing the PMC Ethernet Access Module onto the
6081RC front blade”
on page 24 for the field-installation procedure).
The Fast-Ethernet PMC Module provides two front-panel RJ-45 connectors that can present the two internal
Ethernet ports. When the Fast-Ethernet PMC is installed, you may configure how the Model 6081 presents
Ethernet Ports B and C. When configuring Ethernet ports B and C, for each port you must select one of the
following options:
•
Backplane
—The EdgeRoute directs the internal Ethernet port simultaneously to both:
-
The Ethernet bus within the chassi mid-plane (PSB) and
-
The rear-panel RJ-45 connectors on the rear transition module (if it is installed).
Note
A ForeFront chassis containing a 6081RC with a rear transition mod-
ula and a 6511RC Matrix Switch card will have traffic conflict on
Ethernet ports A and B. Therefore, you must use the Fast-Ethernet
PMC module on the 6081RC for access to Ethernet ports A and B,
not the rear transition module.
