Ethernet Interface Operational Mode Commands

Table 23 summarizes the command-line interface (CLI) commands you can use to monitor and troubleshoot aggregated Ethernet, Fast Ethernet, Gigabit Ethernet, and 10-Gigabit Ethernet interfaces. Commands are listed in alphabetical order.

Table 23: Ethernet Interface Operational Mode Commands

Task	Command
Display status information about aggregated Fast Ethernet or Gigabit Ethernet router interfaces.	show interfaces (Aggregated Ethernet)
