OABR1 / OABR 2:
Role
: Indicates whether the OABR port is set to Master or Slave. The setting can be changed via
the hardware switch <INSERT switch>. See chapter 2.7.
Flow Control
:
-
force:
FC for RX and TX is activated
- auto:
FC is deactivated, because no Auto-Negotiation is made
Speed: 100Mbps or 10Mbps
100BaseTX: Specifies the settings of the Ethernet interface.
Auto-Negotiation
: initiates automatically the maximum possible transmission speed for the
Ethernet-Networkport and as well as negotiation and configuration of the Duplex-mode.
Precondition is that the connected network port also supports auto-negotiation.
Duplex Modus
: Enables the network port to be switched to half-duplex mode to allow compatibility
with certain network devices.
Flow Control
:
-
force FC
: FC for RX and TX is activated, regardless of the result of
Auto-Negotiation
-
auto FC
: FC is negotiated at auto-negotiation. The switch supports RX-FC
and TX-FC. The result depends on what the link partner offers
during the auto-negotiation.
Speed
: Enables the network port to be switched to 10Mbps to allow compatibility with certain
network devices.
USB:
The settings of the USB port are made automatic by the <Ethernet 2 USB driver> and can not be
changed.
2.6.4. VLAN
The VLAN Panel provides the folling configuration functionality
• switch ports can be combined to VLAN-like port groups,
• frame forwarding can be controlled by modifying the Static MAC Table,
• dynamically learned MAC addresses can be displayed.
Future software versions will support the setup of IEEE 802.1q compliant VLANs.
Port Based VLAN
Using Port Based VLANs port groups can be set up. Frames are only forwarded between ports
belonging to the same group.
The group membership is assigned in a matrix where each field represents a communication
direction. The row indicates the source, the column indicates the destination.
For enabling bi-directional communication both corresponding fields must be checked. Arbitrary
combinations can be set up. Inside a port group the other forwarding rules (MAC address lookup)
apply.
