So that just happened to me yesterday! let’s talk about it!
We had to connect one EX4200 switch to another EX4200 switch via the SFP port.
Now as you may know, the EX4200 had a 10gig SFP port , and we only had a 1000BASE-LX SFP Transceiver module (FTRJ1319P1BTL) . pluging that transceiver into the SFP port , but the port does not go up , no light , and when showing the interface we receive the following error: ‘device not found’ .
So, the temporary solution was, is to change the operating mode of the SFP port, using the following command:
# set chassis fpc 0 pic 1 sfpplus pic-mode 1g
First of all, There should two servers, SafeNet & LDAP/Radius server which is including all usernames and passwords. And SafeNet server should be configured to establish sync with LDAP/Radius server in order to pull out all usernames/password.
Second, check with which ports OTP is listening:
Now we should activate the username who’s going to establish the VPN connection via OTP .
Now we need to type the activation code received by the application:
>> >> >>
Now this is how to configure the OTP connection in the MAG:
- The shared secret is what you determine in the OTP server settings, e.g SafeNet
Now you configure realm with correct authentication methods:
And all other roles and page policies …
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
(vty)# show sfp list

info SFP information
- You can use only “show sfp <index of installed sfp>” and you’ll get those kind of information for example:
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
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 .
Note: For more information regarding ssh keys , visit the following site.
Within the Junos Space you can find all the .conf files ‘Configuration Files > Config Files Management’ path . But you want to back it up via bach/script file that runs automatically instead of exporting it from the Space GUI , and you don’t know where those files are stored in the JS directories :
First, good luck with that 🙂
Second, here is the path :
# cd /usr/local/jboss/domain/tmp/servers/server1/.conf/RCS/
This is a description to solve this problem in KB : KB28018
But beside that , lets talk about another situation were this error message might appear.
This error message will also appear when you’re trying to configure both VPN Tunneling and WSAM in the same rule and trying to connect via NC
While you’re trying to backup your Junos Space VM machine via the VMware Tools, and you receive the following error:
FTL – vfm_freeze: method: VMware_v2, type: FIM, function: VMware_v2_freeze
as part of my research in Junos space resources I can see that “Junos Space Network Management Platform is not certified to be used with VMware tools”
This should work From Junos Space Network Management Platform Release 16.1R1 onward.
