PRP Ethernet Connection Equipment
There are two RJ-45 Ethernet interface receptacles on the PRP, p roviding media-dep endent
interface (MDI) Ethernet ports. These connections support IEEE 802.3 and IEEE802.3u
interfaces compliant with 10BASE-T and 100BASE-TX standards. The transmission speed
of the Ethernet ports is auto-sensing by default and is user configurable.
The RJ-45 receptacles on the PRP provide two physical connection options for Ethernet
interfaces. RJ-45 cables are not available from Cisco Systems; they are available from
outside commercial cable vendors. To connect cables to the PRPs Ethernet interfaces (ports
labeled ETH0 and ETH1), attach the Category 5 UTP cable directly to a RJ-45 receptacle
on the PRP.
The Ethernet interfaces on the PRP are end-station devices, not repeaters; therefore, you
must connect an Ethernet interface to a repeater or hub.
Note Only connect cables that comply with EIA/TIA-568 standards. (See Table3-7 and
Table3-9 for cable recommendations and specifications.)
Caution The Ethernet ports are primarily used as a Telnet port into the Cisco 12000 series
Internet 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. Cisco strongly cautions you to consider the
security implications of switching on CEF routing functions on these ports.
