jsonrpc support on x440

daniel19 — Wed, 05 Apr 2017 20:23:00 GMT

Hi ,
I would like to know if it is possible to enable the jsonrpc in Extreme x440.
The firmware I am currently using is 16.1.3.6 patch1-8.

I get a 404 response from:
http:///jsonrpc/

404 Not Found
404 Not Found
The requested URL '/jsonrpc/' was not found on this server.
XOS 22nov2004
Can you confirm that it is supported only on the new EXOS 21.1 as mentioned here?
https://community.extremenetworks.com/extreme/topics/ansible-for-xos

It that is the case the the new os is not available for x440 . What can be an alternative solution?

Correct. JSONRPC support was introduced in EXOS 21.1.

For earlier EXOS releases, I have a kind of odd way to do JSONRPC over telnet session that I never published.
I have python code examples on how a server would use this.

Server:

connects to a switch via telnet

Authenticates (username/password)
starts a script tJSONRPC.py on the switch which takes over the connection.
communicates JSONRPC with the switch point to point over the dedicated session.

Switch:

authenticates telnet client connection
accepts command to start tJSONRPC.py (run script tJSONRPC.py)
session communicates JSONRPC (method=cli) until closed.

Would you be interested in trying this out?

I hesitated to talk about it, as this is work in progress, looks like I'm too conservative 🙂

Hi,

jsonrpc is available only starting from EXOS 21.1. It would require a big architectural modification to allow EXOS 16.x to support it and there're no plans afaik to do it.

You can pexpect, maybe?

@Stephane Grosjean is this still the case? Is there any way to enable JSONRPC server on an x440-24p-G1 switch that is stuck at verrsion 15 fw?

There's no way to do it prior to 21.1, sorry.
