Management LAN Ports Connection Guidelines
Each RSP/RP card has two RJ-45 media-dependent interface (MDI) Ethernet management LAN ports: MGT
LAN 0 and MGT LAN 1. These ports are used for 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 autosensing scheme on the RSP/RP; the speed is determined by the network that the Ethernet port
is connected to. 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 (100/1000) and duplex (full/half) is supported. Autonegotiation cannot be
disabled.
This table lists the signals used on the Management LAN ports.
