Overview

Configuring Ethernet Ports

The following features are found in the Ethernet ports of the Switch 7750:

■10BASE-T/100BASE-TX Gigabit Ethernet ports support MDI/MDI-X auto-sensing, and can be configured to operate in half/full duplex mode or auto-negotiation mode to negotiate the duplex mode and speed with other network devices. This also allows you to use the optimal mode automatically.

■100BASE-FX-MMF Ethernet ports operate in 100 Mbps full duplex mode. The duplex mode can be configured as full (full duplex) or auto (auto-negotiation). The speed can be set to 100 (100 Mbps) or auto (auto-negotiation).

■1000BASE-X Gigabit Ethernet ports work in gigabit full duplex mode. The duplex mode can be configured as full (full duplex) or auto (auto-negotiation). The speed can be set to 1000 (1000Mbps) or auto (auto-negotiation).

■10/100/1000BASE-T Gigabit Ethernet ports support MDI/MDI-X auto-sensing, and the modes are 1000 Mbps full duplex, 100 Mbps half/full duplex, and 10 Mbps half/full duplex. These modules also support auto-negotiation

■10GBASE-R-XENPAK 10-Gigabit Ethernet ports work in 10-gigabit full duplex mode. The duplex mode can be configured as full (full duplex) or auto (autonegotiation), and the speed can be set to 10000 (10000 Mbps) or auto (autonegotiation).
