Executing vty commands in Juniper routers using PyEZ

Question

I have a requirement where, a python script running in a Juniper router shell needs to execute some commands in vty console of the FPC. I cannot use vty ­c because it may not work properly in all platforms. However, I can use vty fpc0 and then execute the command and exit from there.

Is there a way to execute vty command using PyEZ? If yes, please provide the syntax.

Answer 1

The StartShell class assumes the ability to make a new SSH connection to the target device using port 22. That might not always be a good assumption.

An alternative to using StartShell is to use the RPC equivalent to the request pfe execute command. Here's an example:

>>> resp = dev.rpc.request_pfe_execute(target='fpc0', command='show version')
>>> print resp.text

SENT: Ukern command: show version
