31:24
IMA_OAM_LABEL
IMA OAM label value for the group. This
indicates the IMA version for the current group,
and is used to compare against the IMA
version number carried in octet 6 of the
incoming ICP cells.
23:22
GROUP_SYM_MODE
Group symmetry mode. This is programmed
by PM during group configuration. It is then
used by RIPP to compare against the Group
Symmetry mode field in the incoming ICP cells
during group start-up process. If the two
values do not match, the start-up process will
be aborted. This field is also inserted into
outgoing ICP cells.
The supported values for this field are:
“00”: Symmetrical configuration and operation
“01”: Symmetrical configuration and
asymmetrical operation
“10”: Asymmetrical configuration and
asymmetrical operation
“11”: Reserved
21
GROUP_ICP_FWD_EN
Group ICP cell forwarding enable.
‘0’: Disable ICP cell forwarding to PM.
‘1’: Enable ICP cell forwarding to PM. An
interrupt will be generated upon each ICP cell
to be forwarded to PM, and the content of the
ICP cell will be copied to microprocessor’s
directly accessible registers.
