Parameters Description
--queue_stat <value>
Specifies which priority queues have to be processed in cut-
through mode of operation. Bit 0 corresponds to priority 0, Bit
1 corresponds to priority 1 so on.
cbgen command
--device <ifname> Interface, such as eth0/sw0p0
--index <value>
Index entry number in this controller. Must have.
This value corresponds to “ tsnStreamIdHandle ” of
“ cbstreamidset ” command.
--iport_mask <value> INPUT_PORT_MASK: If the packet is from input port belonging
to this port mask, then it is a known stream and Sequence
generation parameters can be applied.
--split_mask <value> SPLIT_MASK: Port mask used to add redundant paths (or
ports) if split is enabled (STREAM_SPLIT) for a stream. This is
OR'ed with the final port mask determined by the forwarding
engine.
--seq_len <value>
SEQ_SPACE_LOG2: Min value is 1 and maximum value is 28.
tsnSeqGenSpace = 2**SEQ_SPACE_LOG2
For example, if this value is 12, the valid sequence numbers are
from 0x0 to 0xFFF.
--seq_num <value>
GEN_REC_SEQ_NUM: The sequence number to be used for
outgoing packet passed to SEQ_GEN function.
Note: Only lower 16 bits are sent in RED_TAG.
cbrec command
--device <ifname> Interface, such as eth0/sw0p0
--index <value>
index entry number in this controller. Must have.
This value corresponds to “ tsnStreamIdHandle ” of
“ cbstreamidset ” command.
--seq_len <value>
SEQ_SPACE_LOG2: Min value is 1 and maximum value is 28.
tsnSeqRecSeqSpace = 2**SEQ_REC_SPACE_LOG2
For example, if this value is 12, the valid sequence numbers are
from 0x0 to 0xFFF.
--his_len <value>
SEQ_HISTORY_LEN: Refer to SEQ_HISTORY, Min 1 and Max
32.
--rtag_pop_en REDTAG_POP: If True, then the redundancy tag is popped by
rewriter.
