The <get-network-information> equivalent command for show version CLI does not return a <junos-version> element in the response XML for EX2200 in version 12.3/12.3X.

When issuing the <get-network-information> RPC (remote procedure call) on Junos OS 12.3R12-S11 (12.3 code including 12.3X) there is no <junos-version> element in the response XML.  However, other this works fine in other Junos OS versions such as 14.1X53, 15.1X49, 15.1X53, 18.1R3.3, and 19.4R1.10.

Missing <get-network-information> .

Workaround 

The equivalent command to show version in a EX2200 version 12.3 code including 12.3X is  <get-software-information> as shown below:

[email protected]> show version |display xml rpc
<rpc-reply xmlns:junos="http://xml.juniper.net/junos/12.3R12/junos">
    <rpc>
        <get-software-information>
        
    
    <cli>
        <banner>{master:0}
    

The RPC is to see the request. The reply does not include it:

Upgrade to a version greater than 12.3/12.3X to use  <get-network-information> ​ as equivalent for show version.
