Device Status
he "Device Status" page is displayed by default after the authentication step. It displays the main parameters of the unit in real-time.
You can set the "Auto Refresh" option to refresh the statistics automatically. Refresh frequency can be set by the "Auto Refresh Time" parameter. The minimal possible value is “0” seconds and it updates the information instantly. These options are available in the bottom-left side of the "Device Status" screen. The device statistics can also be refreshed manually by clicking the «Refresh» button.
The "Device Status" page has the following sections:
"CPU load" - displays the load percentage of the CPU
"Memory load":
Memory (the data stored in volatile memory are valid only during the current session, until the system reset) displays in real-time the total memory available and the used memory by the running processes.
Flash memory (non-volatile memory) displays in real-time the total memory available and the used memory by the WANFleX and configuration files.
"Interface Statistics" - displays the main parameters of all configured interfaces (physical and logical)
"Switch Statistics" - displays counters of the frames which have been switched or dropped.
Interface Statistics
The software version is displayed in the right side of Interface Statistics section. Following parameters are displayed in the "Interface Statistics" section:
Status
Displays for each interface whether it is “up and running” or not
Packets
Displays the number of received and transmitted packets for each interface since the unit is operational. The local system packets are counted, too (and not only the ones that are passing through the switching groups - data traffic)
Mode
Displays the operation mode of each interface. For example:
10,100 or 1000 Mbps and half or full duplex for the Ethernet interface
Switch Group number for the SVI
MAC Address
Displays the MAC address of each interface
Load
Displays the packet flow through each interface in real-time (for the system and the data traffic)
Interface
Displays all physical and logical set interfaces
Errors
Displays the number of received and transmitted error packets for each interface since the unit is operational
All these counters can be reset by clicking the "Reset All Counters" button.
CAUTION Clearing these counters by clicking the "OK" button in the pop-up page means losing the history data about the functionality of your unit. Avoid this operation unless you are completely sure you don’t need these data in the future. If you are not sure you want to permanently delete all statistics of the device for previous periods without the possibility to recover, click the "Cancel" button.
Switch Statistics
This section displays the number of detected MAC addresses, unicast, broadcast and flood packets switched within each Switch group and also within kernel system (internal traffic), in real-time (since the last reboot). In addition, this section displays in real time statistics on dropped packets from the last configuration update. Total forwarded, dropped, ignored and buffer overflow packets are displayed in real-time below the table.
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
System Log
By clicking the "System Log" button, you can view the "System Log" section.
The "System Log" section allows browsing the unit’s system log. It is possible to minimize/enlarge the system log window by clicking the buttons: 
. You can delete all the information saved in the system log by clicking the "Clear System Log" button. You can hide the System Log section by clicking the "Hide System Log" button.

QoS Statistics
QoS characterizes the entire network performance which is defined by the parameters such as: throughput, latency, jitter, error rate, available bandwidth, etc. In order to provide the guaranteed Quality of Service for certain applications, users or data flows, different prioritization methods are used. The "QoS Statistics" tool displays the statistics of the MINT priority queues for the interface. Priority is one of the parameters which define in what sequence, different types of data traversing every Astrawireless device in MINT network are treated. Each channel may be assigned a priority (for example: P01, P02 … P16). 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 and Weighted Fair Queuing scheduling algorithms. Strict Priority 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 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 Shaping" section.

Table - MINT priorities
Transparent packet prioritization is a WANFleX feature which allows QM manager to transparently map 802.1p/TOS/DSCP priority to MINT priority for the ease of deployment. You have to make sure that “Dot1p Tags” and/or “IP ToS” options are enabled in the "QoS" section.

This section displays the number of inbound packets to each priority queue and the number of dropped packets. Of the 32 priority queues 17 are available for user configuration (from P00 to P16), where 0 is the highest priority. The rest are reserved for the system. Packets with 802.1p priority are distributed to queues with "cosX" values.
