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.
• Autonegotiation of port speed (10/100/1000) and duplex (full/half) is supported. Autonegotiation cannot
The following table lists the signals used on the Management LAN ports.
