“Display” button then shows chosen data below. “Download Selected Data” button generates CSV

(UTF-8 encoded) file of all chosen systems’ data and downloads them as files without displaying them.

Both "Display" and "Download ..." buttons send a request for the required set of statistics data to the

unit. Retrieving and transferring of the data (over the radio channel) takes some time. Downloading

the data is practical when the user needs to process them in a spreadsheet and wants to save some

bandwidth. It is also recommended to use spreadsheet editor like Microsoft Excel or Apple Numbers

to process statistics on mobile devices due to better user experience provided by the specialized apps.

8.3.2. Radio interface statistics

Radio interface statistics provides set of data monitoring the interface between the Router module (IP

routing engine in the unit) and the Radio protocol module. It corresponds to monitoring Radio - Router.

Tx direction: from the Router module to the Radio protocol module. Rx direction: from the Radio protocol

module to the Router module.

MAC address - MAC address of the IP packet. Source for Rx or destination for Tx packets.

IP address – translated MAC address when available. Address 0.0.0.0 is used as a placeholder if the

translation is not available. If the Transparent protocol is used, the translation is not available at all.

UDP, TCP, ICMP, ARP - Packet count and amount of data in Bytes [B] for different protocol types.

Amount of data is summed over the whole Layer 2 Ethernet frame (i.e. all IP headers are counted).

Other – Packets not handled by the previous counters (e.g. VLAN, services, GRE, IPsec (ESP), ...)
