SNMP is not returning the right value, as explained in this link: 

https://community.tp-link.com/en/business/forum/topic/267000

I have 2 WAN configuration. I'm trying to set up SNMP in order to know when one of the WAN link is down 

According to the documentation, OID 1.3.6.1.2.1.2.2.1.8 + the number representing the WAN should show 1 if its up and 2 if its down. 

It always shows 1, no matter what. Here is an example

.1.3.6.1.2.1.2.2.1.8.1,Integer,1
.1.3.6.1.2.1.2.2.1.8.2,Integer,2
.1.3.6.1.2.1.2.2.1.8.3,Integer,2
.1.3.6.1.2.1.2.2.1.8.4,Integer,2
.1.3.6.1.2.1.2.2.1.8.5,Integer,2
.1.3.6.1.2.1.2.2.1.8.9,Integer,1
.1.3.6.1.2.1.2.2.1.8.11,Integer,1

the bold ones are suppose to be the WANs. I know this because if there are OIDs which shows MAC addresses

.1.3.6.1.2.1.2.2.1.6.1,OctetString,
.1.3.6.1.2.1.2.2.1.6.2,OctetString,
.1.3.6.1.2.1.2.2.1.6.3,OctetString,
.1.3.6.1.2.1.2.2.1.6.4,OctetString,
.1.3.6.1.2.1.2.2.1.6.5,OctetString,
.1.3.6.1.2.1.2.2.1.6.9,OctetString,  C0 C9 E3 DA 07 C4
.1.3.6.1.2.1.2.2.1.6.11,OctetString,  C0 C9 E3 DA 07 C3

Thank you very much in advance
