[yxieca]

Description of PR

Refactoring the SNMP PDU controller code.

Summary:

Type of change

• Bug fix
• Testbed and Framework(new/improvement)
• Test case(new/improvement)

Approach

What is the motivation for this PR?

Clean up the SNMP PDU control code to be a generic SNMP controller controls the whole PDU.

How did you do it?

Making PDU controller more generic. It should manage the whole PDU controller instead of just for a single DUT.

For PDU models that know has lane concept. Make lane ID part of the outlet ID. And outlet ID is the portion of OID that can
uniquely identify an outlet on the particular PDU.

Label match is still supported by a passed in hostname.

Add support to query output power wattage
