This section provides information for connecting the GRP to an Ethernet network.
There are two RJ-45 Ethernet interface receptacles on the PRP, providing
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
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.
Only connect cables that comply with EIA/TIA-568 standards. (See
Table 3-9 for cable recommendations and specifications.)
To comply with Telcordia GR-1089 NEBS standard for electromagnetic
compatibility and safety, connect all console, auxiliary, Ethernet, and
BITS (PRP2) interfaces only to intrabuilding or nonexposed wiring or cabling.
The intrabuilding cable must be shielded and the shield must be grounded at both
ends.
The 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. Cisco strongly cautions
you to consider the security implications of switching on CEF routing functions
on these ports.
