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 PRP Ethernet port does not provide external routing functions. Its primary roles are to act as a Telnet port into the router, and to boot or access Cisco software images over a network to which the PRP Ethernet port is directly connected.

Caution Cisco Express Forwarding (CEF) functions on these ports 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.
