FAQ- How does MA5200G Confirm the Interface is Optical or Electrical via Command?

A: Execute disp interface Ethernet */*/* verbose to check Card info/line type, as shown in the following red part:

[5200G]disp interface Ethernet 2/0/1 verbose

Ethernet2/0/1 current state: up

Line protocol current state: up

Hardware is WAN-FastEthernet,

Card info: 100BASE-TX-RJ45 //it represents the interface type is RJ45, viz. electrical interface

Line Type: Twisted-pair   //it represents for twisted-pair, viz. electrical interface

  Address is

  Description: to Eudemon100

  Internet address is 10.10.224.254/24 Is-Primary

  The Maximum Transmit Unit is 1500 bytes, the BandWidth is 100000 Kbits

  Send-frame-type is Ethernet_II, loopback not set

  Negotiation enabled, full-duplex, 100Mbps, No trust 802.1p , urpf disabled

[5200G]disp interface Ethernet 1/0/1 verbose

Ethernet1/0/1 current state: down

Line protocol current state: down

  Hardware is WAN-FastEthernet,

  Card info: 100BASE-FX-SM-IR-LC \\The last characters represent for that the interface type is LC, viz. LC optical interface

    Line Type: SingleMode, WaveLength: 1310nm, Transmission Distance: 15km //Here displays if the optical interface is single-mode or multimode, wavelength, transmission distance. Noticeably, not all optical interfaces could read the information

    Average Optical Output Power: -15~-8 (dBm)

    Receiver Overload: -8 (dBm)

    Optical Center Wavelength: 1310 (nm)

    Receiver Sensitivity: -31 (dBm)
