• Traffic Management (CoS): Class of Service (CoS), also referred to as Quality of Service

(QoS), is a way of managing traffic in a network, by treating different types of traffic with

different levels of service priority. Higher priority traffic gets faster treatment during times of

switch congestion. Priority can be based on VLAN tags, ports, or Differentiated Service Code

Points (DSCP).

• Broadcast Control: The user can configure the threshold for the maximum broadcast packets

per port.

• VLANs: A Virtual Local Area Network (VLAN) is a means to electronically separate ports on

the same switch from a single broadcast domain into separate broadcast domains. By using

VLAN, users can group by logical function instead of physical location. There are 64 VLAN

supported on this switch.

• Spanning Tree Protocol (STP) ensures that only one path at a time is active between any two

network nodes. There are maybe more than two physical path between any two nodes for

redundant paths; STP ensures only one physical path is active and the others are blocked. STP

will prevent an inadvertent loop in a network, which can disable your network due to a

“Broadcast storm”, the result of a broadcast message traveling through the loop again and

again.

• MAC: MAC address table. This menu allows you to set the aging time, as well as entering

static MAC addresses to the switch.

• Multimedia Support (IGMP): The Internet Group Management Protocol (IGMP) is an Internet

protocol that provides a way for network devices to report multicast group membership to

adjacent routers.
