--------------------------------------
Summary: camel-snmp v3 should provide pooling for multiple
endpoint / user authentication
Key: CAMEL-12132
URL: https://issues.apache.org/jira/browse/CAMEL-12132
Project: Camel
Issue Type: Improvement
Components: camel-snmp
Affects Versions: 2.20.1
Reporter: Ricardo Zanini
Priority: Minor
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.
