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 100
Mbps or 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 a port:
