Hello,

I am trying to monitor the traffic on the router. Long time ago I learnt you should not trust that the ifIndex will not change, so I usually check the the WAN interface checking the default route interface, using IP-MIB::ip.ipRouteTableipRouteEntry.ipRouteIfIndex.0.0.0.0 (.1.3.6.1.2.1.4.21.1.2.0.0.0.0), but to my surprise this value is continously changing, actually it seems to be some counter. The rest of the IP-MIB::ip.ipRouteTableipRouteEntry tree seems to be right.

Do you know if this is a bug or simply TP-Link is using non-standard MIBs?

On the other hand, I expected to see at least four interfaces (wan-ethernet, lan-ethernet, wlan, 4G), but I can only see three ones, and also the admin/oper status of one of them is down, so, only two?

IF-MIB::ifDescr.2 = STRING: ifb0
IF-MIB::ifDescr.18 = STRING: ra2
IF-MIB::ifDescr.22 = STRING: eth1.5.0
IF-MIB::ifAdminStatus.2 = INTEGER: down(2)
IF-MIB::ifAdminStatus.18 = INTEGER: up(1)
IF-MIB::ifAdminStatus.22 = INTEGER: up(1)
IF-MIB::ifOperStatus.2 = INTEGER: down(2)
IF-MIB::ifOperStatus.18 = INTEGER: up(1)
IF-MIB::ifOperStatus.22 = INTEGER: up(1)
 

Can you give me a hint?

Thanks
