Re: Unicast traffic control

In networks, unicast is the sending of information packets to a single destination. "Unicast" , that's is normal host2host traffic.

Re: Unicast traffic control

Do you have a voice vlan configured on the ports the phones are plugged into? This may give you priority to voice traffic over normal data traffic. Are the phones on their own vlan? How many devices do you have on your vlans. sounds like a QoS problem. Unicast traffic is very normal.
