  1. Create a Loopback

 

Conecte el puerto de transmisión al puerto de recepción.

Patillas cruzados 1 (TX +) y patillas 3 (RX +) juntas, y patillas 2 (TX-) y patillas 6 (RX-) juntos.

[edit interfaces interface-name (fastether-options | gigether-options)]

set loopback

show

commit

  1. Verify That the Fast Ethernet or Gigabit Ethernet Interface Is Up

show interfaces (fe-fpc/pic/port | ge-fpc/pic/port)

  1. Configure a Static Address Resolution Protocol Table Entry

show interfaces ge-fpc/pic/port

[edit interfaces interface-name unit logical-unit-number family inet address address]

set arp ip-address mac mac-address
show

commit

run show arp no-resolve

  1. Clear Fast Ethernet or Gigabit Ethernet Interface Statistics

clear interfaces statistics fe-fpc/pic/port | ge-fpc/pic/port

  1. Ping the Fast Ethernet or Gigabit Ethernet Interface
