DLP-A421 Provision G-Series Flow Control Watermarks
DLP-A421 Provision G-Series Flow Control Watermarks
Step 1
In the node view, double-click the G-Series card graphic to open the card.
Step 2
Click the

Port
tabs.
Step 3
In the Water Marks column, click the cell in the row for the appropriate port.
Step 4
To provision the Low Latency flow control watermark:
a.
Choose
Low Latency
from the drop-down list.
The Flow Ctrl Lo and Flow Ctrl Hi values change.
b.
Click
Apply
.
Step 5
To provision a Custom flow control watermark:
a.
Choose
Custom
from the drop-down list.
b.
In the Flow Ctrl Lo column, click the cell in the row for the appropriate port.
c.
Enter a value in the cell. The Flow Ctrl Lo value has a valid range from 1 to 510 and must be lower
than the Flow Ctrl Hi value.
This value sets the flow control threshold for sending the signal to the attached Ethernet device to
resume transmission.
d.
In the Flow Ctrl Hi column, click the cell in the row for the appropriate port.
e.
Enter a value in the cell. The Flow Ctrl Hi value has a valid range from 2 to 511 and must be higher
than the Flow Ctrl Lo value.
This value sets the flow control threshold for sending the signal to the attached Ethernet device to
pause transmission.
f.
Click
Apply
.
Note
Low watermarks are optimum for low latency subrate applications, such as voice-over-IP (VoIP)
using an STS-1. High watermarks are optimum when the attached Ethernet device has
insufficient buffering, best effort traffic, or long access line lengths.
Step 6
Return to your originating procedure (NTP).
Purpose
This task provisions the buffer memory levels for flow control on G-Series
Ethernet ports.
