How to view SFP info and properties in JunOS machine

In order to find out info of SFP installed in the Junos machine without taking out the SFP module, do the following commands:

  • Log in to the shell of the relevant FPC. For this example I’ll use fpc4:

master@SW-QFX5100> start shell pfe network fpc4

  • show sfp list

(vty)# show sfp list

  • You can use only “show sfp <index of installed sfp>” and you’ll get those kind of information for example:

Cannot log to Space CLI after installation

First , in order to troubleshoot this issue , you need to be sure that ssh is enabled . How ?

  • power off the machine from VMware workstation or vSphere , or suspend it.
  • power it on
  • after entering user/pass , you’ll be asked to select which mode to enter , check security (5)
  • if appears disable ssh , then ssh is enabled . if not , then enable it .
  • if then is not your problem , then enter the debugging mode (7) and do the following:

write down the command : $ ls -al /etc/ssh/ssh*key

capture

if appears nothing , or zero as it shows in the picture , then you need to re-generate ssh key using the following command:

sudo ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key

and then click Enter twice .

This should solve your problem .

If not , back to “secuirty (5)” section , and try disabling firewall .
