| title | Table - Switch statistics parameters |
|---|
| | Parameter | Description |
|---|
| ID | - The ID of a switch group or Kernel
| | MAC Count | - The MAC addresses number involved in data transmission within this switch group
| | 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)

Once assigned, a priority is automatically recognized by every node inside the MINT network. Each priority value corresponds to a device queue. Once in a queue, every packet is scheduled according to the queuing algorithm set on the device. QM manager supports " Strict Priority Queuing" Queuing and "Weighted Fair Queuing" scheduling scheduling algorithms. "Strict Priority Queuing" Queuing means that the packets from queue with lower priority are not processed until the queue with higher priority is not empty. "Weighted Fair Queuing" uses uses weights for every queue of an interface and allows different queues to have different service shares, depending on that weight.
Every channel is also characterized by the latency parameter. This parameter determines the maximum time for the packets to stay in the channel. If a packet is waiting in a queue of the channel more than the time specified in the latency parameter, then it is discarded. Latency can be set for each channel in the "Traffic ShapingShaping" section.
