Linear FDB Cap
|
Number of entries supported in the Linear
Unicast Forwarding Table (starting at LID=0x0000 going up). LinearFDBCap= 0
indicates that there is no Linear Forwarding Table.
|
Linear FDB Top
|
Indicates the top of the linear forwarding
table. Packets received with unicast DLIDs greater than this value are
discarded by the switch. A valid LinearFdbTop is less than LinearFdbCap. This
component applies only to switches that implement linear forwarding tables and
is ignored by switches that implement random forwarding tables.
|
Multicast FDB Cap
|
Number of entries supported in the Multicast
Forwarding Table (starting at LID=0xC000 going up).
|
Multicast FDB Top
|
Indicates the upper bound of the range of the
multicast forwarding table. Packets received with MLIDs greater than
MulticastFDBTop are considered to be outside the range of the Multicast
Forwarding Table. A valid MulticastFDBTop is less than MulticastFDBCap +
0xC000. This component applies only to switches that implement the optional
multicast forwarding service. A switch shall ignore the MulticastFDBTop
component if it has the value zero. The initial value for MulticastFDBTop shall
be set to zero. A value of 0xBFFF means there are no MulticastForwardingTable
entries.
|
Address Range Config Supported
|
A flag to indicate if address range for
multicast and collectives can be configured.
