14.3 Alarm Profile Screen

Alarm profiles define VDSL port alarm thresholds. The VES-1616FE-55A sends an alarm trap

and generates a syslog entry when the thresholds of the alarm profile are exceeded.

To open this screen, click Basic Setting > xDSL Profiles Setup > Alarm Profile.

Use the top part of the screen (with the Add and Cancel buttons) to add or edit alarm profiles.

The rest of the screen displays the configured alarm profiles.

Number of

Queues

Select the number of queues used to classify traffic. You can select 1, 2, 4 or 8

queues in an IPQoS profile depending on the number of applications you want to

classify.

Note: It’s highly recommended to use 8 queues for traffic

classification.

Queue Id This is the index number of queues listed in the following table according to what

you selected in the Number of Queues field.

PIR PIR is Peak Information Rate. Enter the maximum data rate (128~32768 kbps)

allowed to flow through this device at peak hour. You must enter the number which

is a multiple of 64. See Section 14.2 on page 117 for more information.

CIR CIR is Committed Information Rate. Enter the maximum data rate (64~16384

kbps) guaranteed to flow through this device all the time. You must enter the

number which is a multiple of 64. See Section 14.2 on page 117 for more

information.

Note: CIR < PIR <= two times of CIR in a queue. For example, CIR

is 1024, you must enter the PIR in the same queue equal or

less than 2048 (2 x 1024).

PBS PBS is Peak Burst Size. Enter the maximum packet size (3072~65536 bytes)

allowed to flow through this device at peak hour. You must enter the number which

is a multiple of 256. See Section 14.2 on page 117 for more information.

CBS CBS is Committed Burst Size. Enter the maximum packet size (3072~65536

bytes) guaranteed to flow through this device all the time. You must enter the

number which is a multiple of 256. See Section 14.2 on page 117 for more

information.

Note: The CBS should be equal or less than PBS in a queue.

Level Enter the priority level (0~7) for each queue. "0" is the lowest priority level and "7"

is the highest.

Weight Enter the queue weight (1~127) for each queue.

The VES-1616FE-55A services queues based on their priority level and queue

weight rather than a fixed amount of bandwidth. Queues with larger weights get

more service than queues with smaller weights. This queuing mechanism is highly

efficient in that it divides any available bandwidth across the different traffic

queues and returns to queues that have not yet emptied.

Add Click Add to save what you configured in this screen and creates an IPQoS profile

shown in the first section of the screen.

Cancel Click Cancel to start configuring the screen again.
