Universal Network Terminal TAU-32M.IP 151
'Backup port'
and
'Preemption'
are used for direction reservation. In this case, main and backup
ports are connected to a single switch with Ethernet cables. Backup port should be connected only
when switch settings has been applied and saved.
–
Hubmode
–Ethernet switch operation in hub mode. In hub mode, Ethernet switch will not learn МАС
addresses of devices, that send packets, and all packets will be transferred to all switch ports. We
recommend using this mode for network traffic mirroring from the switch ports to PC (tracing) only.
Update Switch
and
Commit
buttons allow to retain access to the gateway when switch settings are applied.
Click the
Commit
button in 30 seconds interval to confirm newly applied settings, or the previous settings will be
restored.
–
Update Switch
– apply switch settings without restart;
–
Commit
– confirm applied settings.
Use the
Defaults
button to set default parameters (the figure below shows default values).

Tracing, Network Traffic Mirroring
To perform tracing, you should do the following:
1.
Configure hub mode – in
'Switch'
tab, select
'Hubmode'
checkbox, then click
'Update Switch' and 'Commit'
buttons consequently.
2.
Connect a PC to perform the tracing directly to TAU Ethernet port.
3.
Run the application on the PC that captures network traffic. In the application, select Ethernet interface
connected to TAU-32M.IP as a traffic capture interface.
4.
After tracing, save captured traffic into a file.

The '802.1q' submenu
In the
'802.1q'
submenu, you may define the configuration of packet routing rules for switch operation in
802.1q mode.
Gateway switch is equipped with 3 electrical Ethernet ports, 1/2 optic port and 1 port for CPU interactions:
–
Port0, port1, port2 –
electrical Ethernet ports of the device;
–
CPU
– internal port linked to the device CPU;
–
SFP0, SFP1
– optical (SFP) Ethernet ports of the device.
