Description

The queue depth that, when crossed in a rising direction, triggers a hardware interrupt and a recording of the current system time.

The default value of 0 disables the functionality.

On J2 systems this parameter applies to a set of VOQs (and therefore to unicast traffic only). On TD3/TH3 systems this parameter applies to a unicast queue only; the configuration of this leaf is ignored when the queue-template is attached to a multicast-queue.

On TD3 the threshold is rounded up the nearest multiple of 2048 bytes. On J2 the threshold is rounded up to the nearest multiple of 4096 bytes. On TH3 the threshold is rounded up to the nearest multiple of 254 bytes.

Description

Maximum queue depth in bytes. MBS buffer space is not guaranteed.

On J2 systems this parameter applies to a set of VOQs and the default is 256 MB (268435456 bytes).

On TD3/TH3 systems this parameter applies to an egress queue and the default value is based on system-derived ‘alpha’ calculation.

Must be non-zero/non-default in order to add the active-queue-management presence container.
