i connected PC with Sniffer to one of the port and can see traffic from all others ports - ISA server connected to other port and i can see requests to ISA server from all clients PCs.

Sond like all the ports are in the same VLAN. If this is the case. You will see all broadcast that are sent ou on that vlan. That is why you are seeing all the traffic.

Further investigation gave more detailed information. We have Microsoft cluster consisted of 2 servers which connected to 2 ports. They have one mac-address and that mac-address is absent in mac-address-table. I tryed to add static entries to table -
arp 10.20.0.1 02bf.0a14.0001 ARPA GigabitEthernet2/0/20
arp 10.20.0.1 02bf.0a14.0001 ARPA GigabitEthernet2/0/11
But it didn't help...
