Description

we want to use camel with multiple polling endpoints of type SNMP. The restrictions we have are:

• snmp version 3 with authentication and privacy
• each endpoint might have different credentials und securityName (user).

When we configure two endpoint with the URIs

snmp:192.168.56.101:161?snmpVersion=3&type=POLL&oids=1.3.6.1.2.1.7.5.1&authenticationPassphrase=11111111&authenticationProtocol=SHA1
&privacyPassphrase=11111111&privacyProtocol=PrivAES128&securityName=secname111&securityLevel=3

and

snmp:192.168.56.102:1612?snmpVersion=3&type=POLL&oids=1.3.6.1.2.1.7.5.1&authenticationPassphrase=22222222&authenticationProtocol=SHA1
&privacyPassphrase=22222222&privacyProtocol=PrivAES128&securityName=secname222&securityLevel=3

We get exceptions when polling the first endpoint

It seems that after configuration of the second endpoint the security information of the first endpoint is not found/used anymore.
