Hello,

We're currently evaluating OpManager before we migrate from our existing solution, Some reason when we add network for layer-2 discovery it gives Invalid Credential error. 

- We're using Cisco ASA with routing mode.

- We already polled ASA without any issue with given SNMP Credentials, But if we try to run layer-2 discovery it throws a credential error.

- I check all SNMP traps and verify all are working fine but still giving error.
