Model: ER605 (TL-R605)  
Hardware Version: V1
Firmware Version: 1.1.0 Build 20210512 Rel.47886

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

 

Perhaps I'm doing something wrong, could someone bring light? 

Thank you very much in advance

@parosen 

How about checking with this instruction? https://www.tp-link.com/us/support/faq/3043/

@John1234 

 

Thank you very much for you answer

 

Actually the link you posted is one of the documentation I was referring to.

 

According to this document, Status info should be provided in odin .1.3.6.1.2.1.2.2.1.8 tree.

 

Using smnpwalk in my router the tree returns this:


.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

 

I can tell 9 and 11 are the WANs, because if I look in the whole odin tree that is returning, I can find their mac addresses

.1.3.6.1.2.1.2.2.1.6.2,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

 

if there is a  link down, .1.3.6.1.2.1.2.2.1.8.9 or .1.3.6.1.2.1.2.2.1.8.11, depending on which one is down, should be returning something different to 1

 

As I tried to configured this with the last firmware already, I don't if this is a problem introduced by the last firmware version, or it was always like this or I'm doing something wrong
