Replacements for obsolete SNMP OIDs for M4350-8X8F

I'm using SNMP to query some properties of a M4350-8X8F switch.  One of the properties I need is the current authenticator PAE state for a give interface. I see there is an OID agentDot1xClientAuthPAEstate in the NETGEAR-DOT1X-ADVANCED-FEATURES-MIB that seems to do what I need, but its status is obsolete and no alternatives are listed.

I would also like to query the current Guest VLAN ID of a given port.  The OID agentDot1xGuestVlanId in the same MIB looks promising, but it is also obsolete and I can't find the alternate OID it is referencing agentAuthMgrNoResponseVlanId in any of the MIB files. 

Does anyone know which OIDs I can use to get these properties, or if it is simply not possible to do this anymore with SNMP?
