ibSmaSwLinearFdbTop
Module: SMA-MIB
OID (symbolic): SMA-MIB::ibSmaSwLinearFdbTop
OID (numeric): 1.3.6.1.3.117.3.1.2.4
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: Indicates the top of the linear forwarding database. 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. For the latter cases a 0 is returned.
What is ibSmaSwLinearFdbTop?
The highest destination LID this switch's linear forwarding table currently covers; unicast packets addressed above this LID are dropped. Only meaningful on switches using a linear (rather than random) forwarding table, which report 0 here.
