• Provide data security by restricting all traffic to the originating VLAN.
Traffic Prioritization – This switch prioritizes each packet based on the required
level of service, using four priority queues with Weighted Round Robin Queuing. It
uses IEEE 802.1p and 802.1Q tags to prioritize incoming traffic based on input from
the end-station application. These functions can be used to provide independent
priorities for delay-sensitive data and best-effort data.
This switch also supports a method of prioritizing layer 3/4 traffic to meet application
requirements. When this service is enabled, the priorities are mapped to a Class of
Service value by the switch, and the traffic then sent to the corresponding output
queue.
Link Layer Discovery Protocol (LLDP) – LLDP is used to discover basic
information about neighboring devices on the local broadcast domain. It uses
periodic broadcasts to advertise information about the sending device. Advertised
information can include details such as device identification, capabilities and
configuration settings. This information can be used by SNMP applications to
simplify troubleshooting, enhance network management, and maintain an accurate
network topology.
Power-over-Ethernet (PoE) – The switch’s eight RJ-45 ports support the
IEEE 802.3af PoE standard that enables DC power to be supplied to attached
devices over wire pairs in the connecting Ethernet cable. Any 802.3af compliant
device attached to a port can directly draw power from the switch over the Ethernet
cable without requiring its own separate power source. This capability gives network
administrators centralized power control for devices such as IP phones and wireless
access points, which translates into greater network availability.
A maximum PoE power budget for the switch (power available to all switch ports) is
defined so that power can be centrally managed, preventing overload conditions at
the power source. If the power demand from devices connected to the switch
exceeds the power budget, the switch uses port power priority settings to limit the
supplied power.
