54.10.1 Port Setup Commands Examples
The following commands configure port 1 on a card installed in slot 6.
Select port 1 in slot 6 and name the port 2406.
Set the port to 1 Gb and full duplex.
flow-control
Enables flow control on the interface.
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 OLT uses IEEE 802.3x flow control in full duplex
mode and back pressure 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.
Backpressure 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
Flow Control to enable it.
C 13
bpdu-control
<peer|tunnel|discard|network>
Sets how Bridge Protocol Data Units (BPDUs) are
used in STP port states. Configure the way to
treat BPDUs received on this port. You must
activate bridging control protocol transparency
first.
peer
: process any BPDU (Bridge Protocol Data
Units) received on this port.
tunnel
: forward BPDUs received on this port.
discard
: drop any BPDU received on this port.
network
: process a BPDU with no VLAN tag and
forward a tagged BPDU.
