Parameters on response.
ips_hdr
ips_hdrips_hdr
ips_hdr
IPS Header. For definition, see Section 6-1-1. Handles from request are
swapped.
6-3-14. CBI_M2_FLUSH_BUFFERS The L3 sends this message to L2 following a processor outage to request that
it discard any data messages pending transmission before the processor
outage occurred, and resume sending data messages to its peer L2 process.
This message is referred to as “clear buffers” in the ANSI version of the MTP2
spec.
There is no response to this message if the major version of the L2 is ITU.
If the major version of the L2 is ANSI, the L2 sends a CBI_M2_RTB_CLEARED
message when it has cleared the retransmission buffer, and a
CBI_M2_RB_CLEARED message when it has cleared the receive buffer. These
two response messages may be sent in either order.
