Auxiliary Port Signals
The RP Auxiliary (AUX) port is a RJ-45 interface for connecting a modem or other data communication
equipment (DCE) device (such as another router) to the RP. The AUX port supports hardware flow control
and modem control.
The following table lists the signals used on the Auxiliary port.

Management LAN Ports Connection Guidelines
The RP has two RJ45 media-dependent interface (MDI) Ethernet management LAN ports: MGT LAN 0 and
MGT LAN 1.
These ports are used for IEEE 802.3 10BASE-T (10 Mbps), IEEE 802.3u 100BASE-TX (100 Mbps), or
1000BASE-T (1000 Mbps) Ethernet connections.
The transmission speed of the management LAN ports is not user-configurable. The transmission speed is set
through an auto-sensing scheme on the RP; the speed is determined by the network to which that the Ethernet
port is connected. The combined total input rate of both MGT LAN 0 and MGT LAN 1 is about 12 Mbps.
Management port characteristics are:
• Maximum transmission unit (MTU) is fixed at 1514 and cannot be configured.
• Flow control is disabled and cannot be configured.
• Input unicast packets with an unknown destination address are filtered and dropped.
