Instant On - Wired

hi,

we have mpls network here and one of our remote site has strange promlem. There is  3 networks vlan 2,20,10. Others works just fine but vlan 20 will irregular freeze(link on router to switch) .
link show green light (not plinking). it will work x days and then hang. Switch does not show any information or alert etc. on logs.
Way to fix this is plug cable off and back to on. network operator has already change that router. I change cable and also port.
Other our sites are working just fine with same kind of devices and configurations.
Any ideas what causes that?

Hi,

I used wireshark to examine the network traffic and I noticed that in one wlan ap port, I had not configured vlan 2 (guest network) traffic at all, instead only vlan 1 traffic, but from that wlan ap, the client asked for an address to the guest network and it was operating on the vlan 1 network (on ap management there was visitor network configured, so ap was showing visitor network). seems to me like vlan traffic was flueted.
