Hello,
I have an RB3011 v.6.47
On sfp1 the rx-too-long counter increasing rapidly. But i cant understand why.
On the top of this interface there is a vlan + mpls+vpls + pppoe.
MTU and L2MTU are the same on both ends:
I captured some packet, but the longhest packet is 1532 (ethernet frame size):
So why the counter is growing? Did you experienced similar problem or point me to a way for debug it?
Thanks!
no one had similar issue? Can mikrotik support explain when the “rx-too-long” counter is increased?
The rx-too-long is one of the error counters. All the rx error counters count frames that the interface has dropped at arrival, so it didn’t let them through to the software layer. Hence sniffing on the interface itself cannot show them.
So if you have control about the sending side of the link, sniffing there might give a clue - the frame hasn’t appeared out of blue, something must have sent it.
Did you found the solution? I Have the same problem with RB4011 on sfp1+ port…
My mtu config:
L3MTU=1500
L2MTU=2040
MPLSMTU=1600
I can see also when I’m sniffing packets at TX way 1532B…
Does anyone got it done?
