Basic Ethernet Port Configuration
Three types of duplex modes are available to Ethernet ports:
z Full-duplex mode (full). Interfaces operating in this mode can send and receive packets
simultaneously.
z Half-duplex mode (half). Interfaces operating in this mode can either send or receive packets at a
given time.
z Auto-negotiation mode (auto). Interfaces operating in this mode determine their duplex mode
through auto-negotiation.
Similarly, if you configure the transmission rate for an Ethernet port by using the speed command with
the auto keyword specified, the transmission rate is determined through auto-negotiation too. For a
Gigabit Layer 2 Ethernet port, you can specify the transmission rate by its auto-negotiation capacity. For
details, refer to. Configuring an Auto-negotiation Transmission Rate .
Follow these steps to configure an Ethernet port:
