Description: Number of entries in the Linear Forwarding Data Base. This counts the number of entries supported in the Linear Unicast Forwarding Table (starting at LID=0x0000 and going up). The InfiniBand SwitchInfo component is called LinearFDBCap. When this count is 0, this indicates that there is no Linear Forwarding Database present.

What is ibSmaSwLinearFdbTableNum?

The number of entries this switch supports in its Linear Unicast Forwarding Database; a value of 0 means the switch has no linear forwarding table and instead uses random forwarding.
