Hi Folks

I’m sure this could be wrapped in a binding and would be of use to people with TP-Link routers or possibly other routers if they provide this OID table and the configuration is updated with the correct OID.

Not to derail this topic, but wanted to point you to a post I created in regards to SNMP for phone detection.

Leveraging SNMP to detect your mobile device

The TP-Link Archer VR9000 has a table of connected devices or ARP entries under the OID: 1,3,6,1,2,1,4,22,1,2,16 Dynamic entries with the IP as the dynamic portion of the key: eg. IP-MIB::ipNetToMediaPhysAddress.16.10.0.0.202 = STRING: 80:58:xx:xx:xx:xx or numerically: .1.3.6.1.2.1.4.22.1.2.16.10.0.0.202 = STRING: 80:58:xx:xx:xx:xx The expiry time on an ARP entry is very short, with the entry for the phone disappearing within seconds of an adminstrative disconnect (turning Wifi OFF on the…

Currently I am working on helping with the SNMP 2.x binding not working the same way as the 1.x binding.

SNMP 2.x issue

Unsure if this is the method to reporting this, but I have started testing SNMP 2 and come across an issues setting the thing as a switch value. While the onvalue works great, the offvalue is failing as the full OID is a dynamic one and just disappears, the parent OID of .1.3.6.1.2.1.3.1.1.3.800.1 reports all of the IPs from the ARP table. Type switch : phone_thing1 [ oid=".1.3.6.1.2.1.3.1.1.3.800.1.192.168.1.5", mode="READ", datatype="IPADDRESS", onvalue="192.168.1.5", offvalue…

If you want to throw up any success you have with the TP-Link router on the first link, I’m sure others would enjoy having this as another option rather than trying to get a hold of Cisco equipment just for SNMP purposes.
