Looking at the switch statistics I can see a huge number of UDP-other flows
(98,35% of total number of flows). Most of them (over a 99,99%) are of the
same type, which is:

SrclIPaddress DstIPaddress SrcPort DstPort
DNS_server NW_server 0035 1287 (these are HEX values of
port numbers)

Can anybody help me to find out why I have such a huge traffic between my
NetWare and DNS server (about 75% of WAN link capacity between them)?
