Release Information
For ATM2 IQ interfaces only, define the early packet discard (EPD) threshold on a
Description
VC. The EPD threshold is a limit on the number of transmit packets that can be
queued. Packets that exceed the limit are discarded. For interfaces configured in
trunk mode, you can also configure dual EPD thresholds depending on the packet
loss priorities (PLPs). For more information, see "Configuring Two EPD Thresholds
per Queue" on page 336.
Approximately 1 percent of the available cell buffers. If shaping is enabled, the default
Default
EPD threshold is proportional to the shaping rate according to the following formula:
The minimum EPD threshold value is 48 cells. If the default EPD threshold formula
results in an EPD threshold of less than 48 cells, the result will be ignored, and the
minimum value of 48 cells will be used.
