SNMP - Wrong traffic values with td-w89970?
SNMP - Wrong traffic values with td-w89970?
Model : TD-W8970
Hardware Version : V1
Firmware Version : 0.6.0 2.12 v000c.0 Build 140613 Rel.31066n

Hi,
I'm trying to monitor incoming and outgoing traffic in my TD-W8970. I activated snmp in router settings and then set up a netxms server for monitoring. Added the router to netxms and after an interface polling I got a lot o interfaces: wifi0, sit0, ppp0, nas0_1, nas0, lo, ip6tnl0, ifb1, ifb0, gre0, eth1, eth0.5, eth0.4, eth0.3, eth0.2, eth0, br0, ath0. I didn't know exactly which interfaces to monitor, so at first I added all using OIDS .1.3.6.1.2.1.2.2.1.10 and .1.3.6.1.2.1.2.2.1.16
Then I started generating traffic between different nodes in order to test monitoring and check which interfaces I was really interested of. The fact is that, apart some exceptions, all tests I did didn't gave me correct values:
Tests:
- Download something from internet (ubuntu iso) connected in LAN with Ethernet Cable: According to my Laptop I reached 800KB/s (~7Mb/s) while in netxms I saw eth0 incoming traffic raising from ~0 to 18KB/s. All the other interfaces didn't see any change (neither ath0 and ppp0) and
- Transfer big file between two pcs directly connected in LAN with the router: 34MB/s on my laptop and... nothing different in netxms
- Send file from pc connected in LAN with Ethernet Cable to pc connected in WLAN: eth0 and br0 show the actual traffic speed, the others (also wifi0) nothing
- Upgrade firmware: I upgraded firmware to the latest version before doing any test and when I sent the new firmware file to the router I saw a peak (~8MB doesn't take a lot to upload) in netxms, but I don't remember on which interface
- Download something from internet (ubuntu iso) connected in WLAN: ath0 shows the correct traffic rate (even if out speed is download speed, and in is upload), ppp0 out and nas0_1 raised from ~0 to 18KB/s (ppp0) and 28KB/s(nas0_1). Actual speed was ~850KB/s
I don't know what to think. Here snmp support seems very bugged, but I read about some user with same router model (don't know hardware version) using it. Maybe I just do something wrong
Thank you for reading. I hope this test are useful for troubleshooting this behavior
Suggestions?
P.S. On linux I tried to do snmpwalk to ath0 out (.1.3.6.1.2.1.2.2.1.16.15) and saw similar values to Netxms ones, so I don't think it's Netxms' fault. Furthermore I use it at work for similar task and it works well
