Displaying Junos OS Information

You can display Junos OS version information and other status to determine if the version of Junos OS that you are running supports particular features or hardware.

1. Make sure you are in operational mode.
2. To display brief information and status for the kernel and Packet Forwarding Engine, enter the show version brief command. This command shows version information for Junos OS packages installed on the router. For example:

   user@host> show version brief 
   Hostname: host
   Model: m7i
   JUNOS Base OS boot [9.1R1.8]
   JUNOS Base OS Software Suite [9.1R1.8]
   JUNOS Kernel Software Suite [9.1R1.8]
   JUNOS Crypto Software Suite [9.1R1.8]
   JUNOS Packet Forwarding Engine Support (M/T Common) [9.1R1.8]
   JUNOS Packet Forwarding Engine Support (M7i/M10i) [9.1R1.8]
   JUNOS Online Documentation [9.1R1.8]
   JUNOS Routing Software Suite [9.1R1.8]
   
   user@host> 

   If the Junos Crypto Software Suite is listed, the router has Canada and USA encrypted Junos OS. If the Junos Crypto Software Suite is not listed, the router is running worldwide nonencrypted Junos OS.

3. To display detailed version information, enter the show version detail command. This command display shows the hostname and version information for Junos OS packages installed on your router. It also includes the version information for each software process. For example:
   user@host> show version detail
