Interfaces interface-name (fastether-options Simply including the loopback statement at the [edit There is no option to use a local or remote statement. On anĮthernet interface, you cannot create a remote loopback, therefore Of the PIC but does not test the transmit and receive ports. A local loopback tests the interconnection When you create a local loopback, you create an internal loop In configuration mode, go to the following hierarchy level: edit interfaces interface-name (fastether-options | gigether-options)Ĭonfigure the local loopback: [edit interfaces interface-name (fastether-options | set loopbackįor example: [edit interfaces fe-1/0/0 showįor example: [edit interfaces fe-1/0/0 commit The transmit port to the receive port, follow these steps: To configure a local loopback without physically connecting Perform Steps 2 through 8 from Diagnose a Suspected Hardware Problem with a Fast Show interfaces (fe- fpc/pic/port | ge- fpc/pic/port ) extensive Interface (fe- fpc/pic/port | ge- fpc/pic/port count 100 rapidĬheck for Fast Ethernet or Gigabit Ethernet Interface Ping the Fast Ethernet or Gigabit Ethernet Interface Interface-name unit logical-unit-number family inet addressĬlear Fast Ethernet or Gigabit Ethernet InterfaceĬlear interfaces statistics fe- fpc/pic/port | ge- fpc/pic/port
