Step 4 end 退回 . Step 5 show interfaces interfaceid description or show runningconfig 驗(yàn)證 . Step 6 copy runningconfig startupconfig 保存 Use the no description interface configuration mand to delete the description. This example shows how to add a description on Fast Ether interface 0/4 and to verify the description: Switch config terminal Enter configuration mands, one per line. End with CNTL/Z.
