View Multicast Group Details
1. Enter the show ib sm multicast {subnet-prefix prefix | all} command.
Example
• View the subnet-prefix of the multicast group.
• View the Multicast Global ID (MGID), which is the 64-bit multicast GID address for the multicast
group.
• View the Queue Key (QKey), which is the 16-bit Q-Key of this multicast group. The queue key is
a construct that is used to validate a remote sender’s right to access.
• View the Local Identifier (MLID) for this multicast group. The LID is a 16-bit address that is
assigned to a port by the subnet manager. It is used to direct packets within the subnet.
• View the Maximum Transmission Unit (MTU) for the multicast group.
•View the TClass for the multicast group. Specifies the TClass to use in the Global Route Header
(GRH), if one is used. A GRH is used in packets that are assigned to destinations outside of a
sender’s local subnet.
• View the partitions to which the multicast group belongs in the PKey field. Refer to “About
Partitions” on page 53.
• View the traffic rate for the multicast group.
•View the packet life time of the multicast group.
