Step 1 configure terminal 進入配置狀態.
Step 2 interface interface-id 進入連接埠配置狀態.
Step 3 speed {10 | 100 | 1000 | auto | nonegotiate} 設置連接埠速率 注 1000 只工作在千兆口. GBIC模組只工作在1000 Mbps下. nonegotiate 只能在這些GBIC上用 1000BASE-SX, -LX, and -ZX GBIC.
Step 4 duplex {auto | full | half} 設置全雙工或半雙工.
Step 5 end 退出
Step 6 show interfaces interface-id 顯示有關配置情況
Step 7 copy running-config startup-config 保存
