interace speeds and snmp

RouterOS General
1

I have an rb433ah running 3.24 and can’t graph the true speeds through the box with mrtg/snmp.

I think it comes down to this. RouterOS isn’t sending accurate interface max speeds via snmp.

As you see here, ethernet interfaces are an accurate 100mbps.

However, the wireless interface is limited to 11mbps. I’m using a 48-54mbps modulation on the wireless link and it can do 30+mbps.

The vlans should be the same speed as the physical interface they are on.

The routerboard is older than 30 days, so I haven’t contacted support. Anybody else run into this?

Hello all,

I have a similar situation. Rb 433ah, RouterOS 4.16, atheros wireless interface (ubnt sr71a) configured to operate in 802.11n (NV2) and the snmp interface reports only 11Mbps.

Any ideas?
