Advanced

The Advanced page allows professional users to operate the more complicated features of the device, which include VLAN, Spanning Tree, Port
Trunking, Multimedia support (IGMP), traffic prioritization, SNMP, and port mirroring. These features are powerful and can degrade or damage a
network's performance if improperly used.
Port Mirroring: Users can designate a port for monitoring traffic from one or more other ports or of a single VLAN configured on the switch.
o
The switch monitors the network activity by copying all traffic from the specified monitoring sources to the designated monitoring port, to
which a network analyzer can be attached.
Port Trunking: a feature that allows multiple links between switches to work as one virtual link (aggregate link). Trunks can be defined for
o
similar port types only. For example, a 10/100/1000 port cannot form a Port Trunk with a GBIC port. Up to four trunks can be operating at
the same time.
Multimedia Support (IGMP snooping): The Internet Group Management Protocol (IGMP) is an Internet protocol that provides a way for
o
network devices to report multicast group membership. By using this protocol, networking devices can reduce broadcast traffic. IGMP
snooping is a way to participate in this protocol without interfering.
Traffic Prioritization (CoS): Class of Service (CoS), also referred to as Quality of Service (QoS), is a way of managing traffic in a network,
o
by treating different types of traffic with different levels of service priority. Higher priority traffic gets faster treatment during times of
switch congestion.
VLANs: A Virtual Local Area Network (VLAN) is a means to electronically separate ports on the same switch from a single broadcast
o
domain into separate broadcast domains. By using VLAN, users can group by logical function instead of physical location. This switch
supports up to 64VLAN's.
Spanning Tree Protocol (STP) ensures that only one path at a time is active between any two network nodes. There are maybe more
o
than one physical path between any two nodes for redundant paths; STP ensures only one physical path is active and any others are
blocked from forwarding traffic. 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 management
