Chapter 7 Managing Module Hardware

Note: Under normal circumstances, the early packet discard threshold should not be changed. Before attempting to change the thresholds, contact Avaya Technical Support.

The Cell Loss Priority (CLP) mechanism allows low priority cells (with CLP set to 1) to be discarded first. The CLP threshold cannot be set by the user.

Displaying the packet discard threshold for modules

To display the current packet discard thresholds for all modules, use the hardware packetdiscard command.

Command: M15-155s8:/>hardware packetdiscard

Output: EPD 80%

The information displayed is the percentage threshold that is currently set for Early Packet Discard (EPD). The default EPD threshold is 80%. When the switch’s buffers are more full than the EPD threshold then the switch module will discard NEW AAL5 frames on UBR circuits.

Changing the packet discard thresholds for modules

You can change the default thresholds for packet discard.

Decreasing the percentage will cause packets to be discarded at an earlier stage during congestion.

Increasing the percentage will cause the congestion to reach a higher level before the packet discard threshold is reached and packets are discarded.

To disable packet discard enter 0 for EPD.

Note: Under normal circumstances, the packet discard thresholds should not be changed. Before attempting to change the thresholds, contact Avaya Technical Support.

To change the packet discard thresholds for an module, use the hardware packetdiscard <epd%> command.

Command:

M15-155s8:/>hardware

packetdiscard

<epd%>

Example:

M15-155s8:/>hardware

packetdiscard

70

Parameters:

<epd%>

The new percentage threshold for EPD.
