Description
Supports inhibited, failed, fault, or
misconnected report causes for unusable
links.
User can increase the minimum number of
links in a group to keep it from entering an
alarm (nonoperational) state if constituent
links fail.
User can configure the values of alpha (), beta
(), and gamma () per link set (links 1 through
8, 9 through 16, or 17 through 24) to control
the IMA Frame Sync procedure.
Transitions from any state to HUNT state
when cells are no longer being received from
the physical layer.
Maintains IMA frame synchronization when
one of the two stuff ICP cells has a header
error control (HEC) or CRC error.
Out-of-IMA-frame anomalies maintained.
Far-end transmit failure count maintained.
Far-end receive failure count maintained.
Count stuff events inserted in transmit or
receive directions.
Far-end group failure count maintained.
IMA performance parameters are accessible
via SNMP for 15-minute and 24-hour
intervals, and since startup. (Only total
statistics are provided because startup
statistics are available from the command
line.)
Implementation-specific transmit fault or
receive fault conditions are declared at the
near end.
