Is it normal to lost packets on internal interface?

Thu Oct 09, 2008 4:17 pm

Hi all.
I'm wondering is it normal to lost packets on internal interface of Mikrotik?
I've run MTR from inside lan pinging internal interface of my Mikrotik and have got this result:

|------------------------------------------------------------------------------------------|
| MTR statistics |
| Host - % | Sent | Recv | Best | Avrg | Wrst | Last |
|------------------------------------------------|------|------|------|------|------|------|
| gateway.local - 1 | 1557 | 1553 | 0 | 12 | 391 | 0 |
|________________________________________________|______|______|______|______|______|______|

1 % lost and some packets time too long for local lan

I use 433AH and cpu load about 10 % most time without spike. Also no queues are red.
I've tried to ping other servers on the lan and no problem with this.

please check if you have any limitations on input queue.

also would be nice to know more about configuration, because usually it is - either you loose packets or you do not.

Thank you janisk for your reply.
I don't have any limitation on input queue when packet come from internal interface.
What details about configuration should I post?
Config simple: Mikrotik with two external interface, one interface works like backup interface. One internal interface. No hotspot, only Proxy, DNS and VPN server.
Also using Layer7 protocol to mangle p2p but this in forward queue.
Proxy use storage card as cache. Whith caching on storage card processor load is bigger but I've tryied to disable it and ping local interface without it. No change.

Hi,

I recently made a wireless network that connect 120 street video cameras. Using RB433AH as AP with two XR5 and Nanostation5 as CPE. In my study I found that the CPE lost packets, his queue overflow and begins to drop packets.

I would like to know if Mikrotik has any tool or command to know if the AP (RB433AH) is dropping packets too, becouse overflow his buffer or whatever.

I will wait for your answer. Thank You.

Fabian.
