Issue With Adding SNMP RO String

adammmorton — Fri, 01 Mar 2019 12:37:21 GMT

I'm trying to add a RO community string for discovery in the APIC-EM controller and get the following error:

Unable to add Read Community; 400:undefinded

My community string has a @ < > and ! character in it. I'm assuming this is causing the issue as I can put numbers and letters only in there and it works. We have several hundred devices that use this community string and I would rather not have to change it one every device we have. Is there a way to fix this? I'm running version 1.3.3.126

Hi Adam,

that will be the input validation to prevent XSS attacks.

It is the "<" character that is a problem.

Not sure if there is a work around to escape it.

One possible workaround would be to define a new SNMP string on APIC-EM, then use the admin->settings->Device Controllability -> SNMP Autoconfig option to try to provision the new credential?
