8.8 Interface Setup

An IPv6 address is configured on a per-interface basis. The interface can be a physical interface (for
example, an Ethernet port) or a virtual interface (for example, a VLAN). The Switch supports the VLAN
interface type for IPv6 at the time of writing.
Use this screen to set IPv4 loopback interfaces for routing protocols or IPv6 interfaces on which you can
configure an IPv6 address to access and manage the Switch.
Click Basic Setting > Interface Setup in the navigation panel to display the configuration screen.

DESCRIPTION
A concentration of traffic on a port decreases port bandwidth and overflows buffer memory
causing packet discards and frame losses. Flow Control is used to regulate transmission of signals
to match the bandwidth of the receiving port.
The Switch uses IEEE 802.3x flow control in full duplex mode and backpressure flow control in half
duplex mode.
IEEE 802.3x flow control is used in full duplex mode to send a pause signal to the sending port,
causing it to temporarily stop sending signals when the receiving port memory buffers fill.
Back Pressure flow control is typically used in half duplex mode to send a "collision" signal to the
sending port (mimicking a state of packet collision) causing the sending port to temporarily stop
sending signals and resend later.
Select Tx Rx to allow the Switch port to send pause signal to the connected device, and for the
connected device to send a pause signal to the Switch. The Switch will temporarily stop sending
signals after receiving pause signal.
Select Tx to allow the Switch port to send pause signal to the connected device.
Select Rx to allow the connected device to send a pause signal to the Switch. The Switch will
temporarily stop sending signals.
Otherwise, select Disable.
This priority value is added to incoming frames without a (802.1p) priority queue tag.
Configure the way to treat BPDUs received on this port. You must activate bridging control
protocol transparency in the Switch Setup screen first.
Select Peer to process any BPDU (Bridge Protocol Data Units) received on this port.
Select Tunnel to forward BPDUs received on this port.
Select Discard to drop any BPDU received on this port.
Select Network to process a BPDU with no VLAN tag and forward a tagged BPDU.
You can insert either an SFP+ transceiver or an SFP+ Direct Attach Copper (DAC) cable into the
10 Gigabit interface of the Switch.
Select the media type (sfp_plus or dac10g) of the SFP+ module that is attached to the 10
Gigabit interface.
Click Apply to save your changes to the Switch's run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel to save
your changes to the non-volatile memory when you are done configuring.
Click Cancel to begin configuring this screen afresh.
