SLM248G - Packet loss only on VLAN 20

Hi and thanks for reading.

 

I have one SLM248G Swtich wich has two routers connected to: Router A in port e32 and Router B in port g1. The first one works just fine. But Router B has packet loss only for VLAN ID 20.

 

Traffic capture at Router B shows packets not arriving for several seconds (sometimes 1 packet gets lost and sometimes it lost up to 40 consecutive packets). This only happens with VLAN ID 20. VLAN ID 1, 10, 30, 54, 200, etc, etc has no problems at all.

 

I tried using MTR from linux, because i thought that it would show me the switch losing packets, but mtr doesn't see switch devices.

 

Web Interface show no error packets in g1 interface.

 

I set static routes so all traffic destinated to Router B address goes oug through g1 interface, but didn't help.

 

I'm a network newbie, so any suggestion is appreciated.
