APAR status
Closed as program error.
Error description
Even though the packet rate (or PKEY, MTU, q_key) is specified by the Subnet Manager in IPoIB environment, AIX is not using the specified value and this may block other infiniband interfaces from joining the multicast groups in the same subnet.
Local fix
N/A
Problem summary
If a customer requires to change the packet rate value in the Subnet Manager, the AIX interfaces will not use this value and they will create a multicast groups with the maximum rate available in the line. This will cause ofther members in the network that follow this rule, to fail the join to the multicast group.
Problem conclusion
During the process to join the multicast group in the IPoIB code, verify if the query of the multicast group had the packet rate and other values set, if so, use this values and set the mask to indicate the SM that we will be using those values.
Temporary fix
