Sw1#show interfaces fastEthernet 0/0
FastEthernet0/0 is up, line protocol is down (monitoring)
  Hardware is Fast Ethernet, address is cc00.0e20.f000 (bia cc00.0e20.f000)
  MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec,
     reliability 255/255, txload 1/255, rxload 1/255
  Encapsulation ARPA, loopback not set

Answer 2

肯定了。

监控口的机器一般是不允许做业务的。
