Max. file size

List box {1 kB, 10 kB, 50 kB, 100 kB, 500 kB, 1 MB, max (~2 MB)}, default = 100 kB

When the selected “Time period” expires or the “Max. file size” has been reached, whichever event occurs first, the file is closed. The file can be downloaded later. Monitoring to the file will be implemented in future FW versions.

Time period

List box {1 min, 2 min, 5 min, 10 min, 20 min, 30 min, 1 hour, 3 hours, 24 hours, Off}, default = 5 min

Show time difference

List box {On, Off}, default = Off

When On, the time difference between subsequent packets is displayed in the monitoring output.

Display

List box {HEX, HEX+ASCII, ASCII}, default = HEX

Show output {On, Off}

Rx enabled, Tx enabled

List boxes {On, Off}, default=On

A packet is considered a Tx one when it comes out from the respective software module (e.g. RADIO or Terminal Server) and vice versa. When an external interface (e.g. Interface COM) is monitored, the Tx also means packets being transmitted from the RipEX2 over the respective interface (Rx means “received”). Understanding the directions over the internal interfaces may not be that straightforward, please consult Fig. 8.1, “Interfaces” above for clarification.

All

List box {On, Off}, default On

Monitoring output can also be limited by IP protocol type. Select Off to be able to enable/disable specific protocol output individually – see next parameter(s).

UDP / TCP / ICMP / Other / ARP

List box {On, Off}, default Off

Monitoring output of specific IP protocol limitation.

Offset [B]

Default = 0

Number of bytes from the beginning of packet/frame, which will not be displayed – the monitoring output is truncated by ‘Offset’ bytes at the beginning of the message.

Length [B]

Default = 100

Number of bytes to be displayed from each packet/frame.

Example: Offset=2, Length=4 means, that bytes from the 3rd byte to the 6th (inclusive) will be displayed:

Data (HEX):                 01AB3798A28593CD6B96

Monitoring output:                        3798A285

Bandwidth

List box {LOW, NORMAL, HIGH, UNLIMITED}, default= NORMAL

Monitoring bandwidth limit to prevent overload of management link between client PC and the RipEX unit. LOW (up to ~300 kb/s), NORMAL (up to ~800 kb/s), HIGH (up to ~2 Mb/s), UNLIMITED (up to ~8 Mb/s)

Source port (from) (to)

TCP/UDP source port to be enabled/disabled in the monitoring output. Use “… (to)” parameter to specify range of ports <from – to>.

Destination port (from) (to)

TCP/UDP destination port to be enabled/disabled in the monitoring output. Use “… (to)” parameter to specify range of ports <from – to>.

Dropped frames

List box {On, Off}, default Off

When On, monitoring shows packets which are dropped (e.g. CRC is not valid, buffer overflow, …).

Include management traffic

List box {On, Off}, default = Off

Enable/disable management packets monitoring output.

Include ETH headers

List box {On, Off}, default = Off

Enable/disable ETH headers monitoring output

Include reverse

List box {On, Off}, default = Off

Enable/disable reverse traffic (e.g. TCP reply to a request) monitoring.

Source IP / mask, Destination IP / mask

Monitoring output can also be limited to a specific address range – Source and Destination IP address and mask can be used to define the required range.

Corrupted frames

List box {On, Off}, default = On

Corrupted (“header CRC error”, “data CRC error”, etc.) received frames monitoring output can be suppressed. This can be useful when the communication in the channel is heavily disturbed by interference or noise, resulting in „garbage” messages which can make the monitoring output difficult to read.

Other modes

List box {On, Off}, default = Off

When Promiscuous mode is enabled, the unit is capable to monitor (receive) frames from the other RipEX units even if the other unit(s) is(are) working in the other Unit mode (Bridge versus Router).

Frames transmitted under other Unit mode may not be properly ‘analyzed’. In such a case frames are displayed in raw data format.

Include headers

List box {None, Packet (IP), Frame (ETH)}, Default= None

Promiscuous mode

List box {On, Off}, default = Off

Link Control Frames

List box { On, Off}, default = Off

Source IP / mask, Destination IP / mask (router)

Monitoring output can also be limited to a specific address range – Internal (router) Source and Destination IP address and mask can be used to define the required range.

Source IP / mask, Destination IP / mask (radio)

Monitoring output can also be limited to a specific address range – Radio interface Source and Destination IP address and mask can be used to define the required range.
