AXLAPI addSNMPCommunityString - CUCM 12.5 and CUCM 14.0

[Mark Dugas]

We have over 400 servers that are "managed" by our field IT.  We need to reset all of the SNMP strings on all pub/sub.  I am attempting to do it via Python and the addSNMPCommunityString API.

1) In version 12.5 I can set the SNMP string on the publisher.  CUCM has an option on the GUI to Apply to All Nodes, but there is no option like that in the API. My API call will just set the Publisher because that is the server I create the Zeep client service with.  Question:  is it possible to set pub SNMP with API and somehow invoke an Apply to All Nodes

2) In version 14.0, using the 14.0 WSDL, the exact same code that works on 12.5 yields:  /usr/local/Snmpri/conf/temp.cnf (Read-only file system).  Has anyone run into something like this?

Thanks.

Mark

Hi Mark!

I believe you are right.
I've checked the scheme and haven't found a way to "apply Config" to all nodes.

Workaround:
In your place I would query the list of nodes and save the result in a LIST "nodes"
Then use a for loop (for node in nodes) to POST your snmp community (addSNMPCommunityString) to each node(s).

If you need an example of this in python, please let me know

BjeornMartin has the right idea   You can see the samples here for help with sending an AXL request to a specific host, e.g.:

# Create the Zeep client with the specified settings
client = Client( WSDL_FILE, settings = settings, transport = transport,
        plugins = plugin ) 

service = client.create_service( "{http://www.cisco.com/AXLAPIService/}AXLAPIBinding",
                                f'https://{os.getenv( "CUCM_ADDRESS" )}:8443/axl/' )

The error seen on v14 seems to be a defect, I've opened this to track the issue: CSCvz94894

FYI it looks like there is a known issue around AXL SNMP operations in general with v14: https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvy78363

This defect is internal at the moment (not publically viewable), but looks to have been fixed/verified and assume it will appear in the next v14 Service Release.  It may be possible to request the fix in an interim 'Engineering Special' release from TAC if required.
