    ParameterDescription
    Unicast
    • Sending a packet to a single host (network destination) identified by a unique address
    Broadcast
    • Sending a packet to all hosts (network destinations) simultaneously (broadcasting is done by specifying a special broadcast address on packets)
    Flood
    • Sending a packet along the same link multiple times (without specifying a destination address for the packets)
    • Several copies of the same packet would ultimately reach all nodes in the network in flooding
    STP
    • Spanning Tree Protocol - standardized as IEEE 802.1D
    • Creates a spanning tree within a network of connected layer-2 bridges (typically Ethernet switches) and disables those links that are not part of the spanning tree, leaving a single active path between any two network nodes
    • The value displayed in the Switch Statistics table represents the number of the packets blocked by the Spanning Tree Protocol
    Unreachable
    • The sender could not reach the specified network destination
    • The value displayed in the Switch Statistics table represents the number of the packets dropped because they flood to unreachable destination

    Firewall

    • A software or hardware-based network security system that controls the incoming and outgoing network traffic by analyzing the data packets and determining whether they should be allowed through or not, based on applied rules set
    • The value displayed in the Switch Statistics table represents the number of the packets dropped by the firewall system in the network
    Possible loop
    • A switching or bridging loop occurs in a network when there is more than one Layer 2 path between two endpoints
    • Because a physical topology that contains switching or bridging loops is needed for the redundancy reasons, the solution is to allow physical loops, but create a loop-free logical topology using the spanning tree protocol (STP) on the network switches
    • The value displayed in the Switch Statistics table represents the number of the packets dropped because they belong to a possible loop (more than one port declares same packet source)
    Discard
    • The value displayed in the Switch Statistics table represents the number of the packets dropped by the configuration (for example: "switch group N start [discard]")
    MAC Limit
    • MAC address-table limit reached (switch maxsources (MAXSOURCES|0) # default 5000)
    • The value displayed in the Switch Statistics table represents the number of the packets dropped because the limit of MAC address-table was reached
    Reverse
    • The value displayed in the Switch Statistics table represents the number of the packets dropped because they have the same source and destination port (the frame came to the unit through one port and according to the switching table it must leave through the same port)

    The performance test with “Use MINT” option is very useful in case you want option allows to get estimation about the best wireless link throughput (excluding the information about the bitrate, retries level, etc.), is activated by default.

    • "Priority (0-16)" - By default, it is 16, which is lower than the data traffic that has priority 15. You can increase the test priority by setting a lower value.

    The bitrates list on the "Performance test" tool consists of the bitrates that correspond to the channel bandwidth set on the unit (5/10/20/40MHz). To perform the tests for the bitrates related to the other channel bandwidth, you need to reconfigure the channel bandwidth (the “Channel Width” parameter in the "Radio Setting" section of the "Basic Settings" page) on both units within the tested link.
