11.14 Alarm ADSL Profile Screen
Click Profile> Alarm ADSL in the navigation panel to open the following screen. Use this screen to
configure alarm profiles for the ADSL ports. Later you can apply the alarm ADSL profiles to ADSL
ports in the
ADSL Port Setup screens.
Alarm ADSL profiles define ADSL port alarm thresholds. The system sends an alarm trap and
generates a syslog entry when the thresholds of the alarm profile are exceeded.
Cell Delay
Variation
Tolerance
[0~255] Cell Delay Variation Tolerance is the accepted tolerance of the difference between a cell’s
transfer delay and the expected transfer delay. Cell Delay Variation Tolerance applies with all
of the ATM traffic classes. Type the Cell Delay Variation Tolerance here.
Sustained Cell
Rate
[150~300000] The Sustained Cell Rate sets the average cell rate (long-term) that can be transmitted. Type
the Sustained Cell Rate, which must be less than the Peak Cell Rate. Sustained Cell Rate
applies with the variable bit rate traffic classes. You can type a number of (ATM) cells per
second in the first field or type a number of kilobytes per second in the second field to have
the system automatically compute the number of ATM cells per second.
Burst Tolerance
[0~255] Burst Tolerance sets a maximum number of cells that the port is guaranteed to handle
without any discards. Type the Burst Tolerance here. Burst Tolerance applies with the
variable bit rate
traffic classes.
Apply Click Apply to save the changes in this screen to the system’s volatile memory. The system
loses these changes if it is turned off or loses power, so use the Config Save link on the
navigation panel and then the Save button to save your changes to the non-volatile
memory when you are done configuring.
New While you are modifying a profile, you can click New to start configuring a fresh profile
without saving your changes.
Cancel Click Cancel to start configuring the screen again.
The bottom part of the screen lists the configured profiles.
Index This is the number of the ATM profile.
Name This name identifies the ATM profile.
Traffic Class This field displays the type of ATM traffic class: cbr (constant bit rate), vbr (real-time
variable bit rate), nrt (non-real time variable bit rate) or ubr (unspecified bit rate).
Modify Select a profile’s Select radio button and click Modify to edit the profile.
Delete Select a profile’s Select radio button and click Delete to remove the profile.
