Read-only Argument	Type	Description
total-packet-cap (syscap=!prestera-cpss)	num	Total packet capacity. The maximum number of hardware packet descriptors that the device can store in all queues.
total-packet-use (syscap=!prestera-cpss)	num	Total packet usage. The current number of packet descriptors residing in the hardware memory.
total-byte-cap	num	Total tx memory capacity.
total-byte-use	num	Total tx memory usage. The current number of bytes occupied by the packets in all tx queues.
multicast-packet-cap (syscap=!prestera-cpss)	num	Multicast packet capacity. The maximum number of hardware packet descriptors that can be used by multicast/broadcast traffic. Depends on the multicast-buffers setting.
multicast-packet-use (syscap=!prestera-cpss)	num	Multicast packet usage. The hardware makes a copy of the packet descriptor for each multicast destination.
multicast-byte-cap (syscap=!prestera-ac3)	num	Multicast byte capacity.
multicast-byte-use (syscap=prestera-bc2)	num	Multicast byte usage.
mirror-ingress-packet-cap (syscap=!prestera-cpss)	num	Ingress mirror packet capacity. The maximum number of hardware packet descriptors that can be used by ingress mirrored traffic. Depends on the mirror-buffers setting.
mirror-ingress-packet-use (syscap=!prestera-cpss)	num	Ingress mirror packet usage.
mirror-ingress-byte-cap (syscap=prestera-bc2)	num	Ingress mirror byte capacity. Depends on the mirror-buffers setting.
mirror-ingress-byte-use (syscap=prestera-bc2)	num	Ingress mirror byte usage.
mirror-egress-packet-cap (syscap=!prestera-cpss)	num	Egress mirror packet capacity. The maximum number of hardware packet descriptors that can be used by egress mirrored traffic. Depends on the mirror-buffers setting.
mirror-egress-packet-use (syscap=!prestera-cpss)	num	Egress mirror packet usage.
mirror-egress-byte-cap (syscap=prestera-bc2)	num	Egress mirror byte capacity. Depends on the mirror-buffers setting.
mirror-egress-byte-use (syscap=prestera-bc2)	num	Egress mirror byte usage.
shared-packet-cap (syscap=prestera-ac3)	num	Shared packet capacity. The maximum number of hardware packet descriptors that can be shared between ports and tx queues. Depends on the shared-buffers setting.
shared-packet-use (syscap=prestera-ac3)	num	Shared packet usage. The current number of shared packet descriptors used by all tx queues.
shared-byte-cap (syscap=prestera-ac3)	num	Shared tx memory capacity. Depends on the shared-buffers setting.
shared-byte-use (syscap=prestera-ac3)	num	Shared tx memory usage. The current number of shared buffers occupied by the packets in all tx queues.
lossy-pool-packet-cap (syscap=prestera-bc2)	num	Shared packet capacity of the lossy pool.
lossy-pool-packet-use (syscap=prestera-bc2)	num	Shared packet usage of the lossy pool.
lossless-pool-packet-cap (syscap=!prestera-ac3)	num	Shared packet capacity of the lossless pool.
lossless-pool-packet-use (syscap=!prestera-ac3)	num	Shared packet usage of the lossless pool.
lossy-pool-byte-cap (syscap=!prestera-ac3)	num	Lossy pool byte capacity.
lossy-pool-byte-use (syscap=!prestera-ac3)	num	Lossy pool byte usage.
lossless-pool-byte-cap (syscap=!prestera-ac3)	num	Lossless pool byte capacity.
lossless-pool-byte-use (syscap=!prestera-ac3)	num	Lossless pool byte usage.
wred-packet-cap (syscap=prestera-bc2)	num	The maximum packet count that a queue can use above the shared cap to trigger a random tail drop (queueX-shared-packet-cap in /in/eth/sw/qos/port/print usage) . For example, if queue1-shared-packet-cap=3072 and wred-packet-cap=512, WRED triggers when queue1-packet-use exceeds 3072, reaching 100% drop rate at 3072+512=3584 packets.
wred-byte-cap (syscap=prestera-bc2)	num	The maximum byte count that a queue can use above the shared cap to trigger a random tail drop (queueX-shared-byte-cap). For example, if queue1-shared-byte-cap=768KiB and wred-byte-cap=128KiB, WRED triggers when queue1-packet-use exceeds 768KiB, reaching 100% drop rate at 768+128=896KiB.
