Juniper show the SFP information

We use SFP in different devices Cisco, Juniper and other vendor as well. The small form-factor pluggable (SFP) is a compact, hot-pluggable optical module transceiver. SFP transceivers are supporting SONET, Gigabit Ethernet, Fibre Channel, and other communications standards.

Usually, we use SFP in different devices and we need to know the detail information about SFP, Like which port are using which type of SFP, also sometimes we use non brand SFP and then we need to know that SFP is supported this device or not.

Meanwhile, we need to know the cable type model for which speed are using this SFP, like is it 10G SFP or 1G SFP something like this. And we can check the SFP status of is this Single Mode or Multi Mode SFP. Finally most of the time we need to know the wavelength of the SFP. That information we can show from Juniper Devices.

First step, you need to confirm the fpc-slot and pic-slot number. Because, when you want the SFP information of any particular port then you have to be clear about chassis and connected pic slot and fpc slot information. Below giving you the command for collecting the chassis information:

noc# run show chassis hardware

Here you can show the FPC number is 0 and PIC number is 0 after that 0-10 number ports are available here. So we have found now the FPC and PIC number. Now use bellow command for SFP detail information:
noc# run show chassis pic fpc-slot 0 pic-slot 0
FPC slot 0, PIC slot 0 information:
  Type                             32x 1G/10G SFP/SFP+ Builtin

Now, here you find the WaveLength, SFP type Single Mode (SM) / Multi Mode (MM), Speed Type 10G / 1G, Vendor name of SFP Module.
