Connecting PRP Route Processor Cables
Connecting to the PRP Ethernet Ports
Two RJ-45 Ethernet interface receptacles on the PRP provide media-dependent
interface (MDI) Ethernet ports. These connections support IEEE 802.3 and
IEEE 802.3u interfaces compliant with 10BASE-T and 100BASE-TX standards.
The transmission speed of the Ethernet ports is autosensing by default and is
user-configurable.
The RJ-45 receptacles on the PRP provide two physical connection options for
Ethernet interfaces. To connect cables to the PRP Ethernet interfaces (ports
labeled ETH0 and ETH1), attach the Category 5 UTP cable directly to a RJ-45
receptacle on the PRP.
“GRP Ethernet Port Connections” section on page 2-26
for additional
information about the Ethernet ports.
Note
RJ-45 cables are not available from Cisco Systems; they are available from
outside commercial cable vendors. Use cables that comply with EIA/TIA-568
standards.
Caution
Ethernet ports are primarily used as a Telnet port into the Cisco 12000 series
router, and for booting or accessing Cisco IOS software images over a network to
which an Ethernet port is directly connected. Cisco Express Forwarding (CEF)
functions are switched off by default for security reasons. We strongly caution you
to consider the security implications of switching on CEF routing functions on
these ports.
Use the following procedure to connect an Ethernet cable to the PRP RJ-45
Ethernet receptacle:
Step 1
Plug the cable directly into the RJ-45 receptacle.
Step 2
Connect the network end of your RJ-45 cable to a switch, hub, repeater, DTE, or
other external equipment.
