ibSmSwitchInfoLinearFdbTop
Module: IB-SM-MIB
OID (symbolic): IB-SM-MIB::ibSmSwitchInfoLinearFdbTop
OID (numeric): 1.3.6.1.3.117.7.1.4.1.1.6
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: Indicates the top of the linear forwarding table. Packets received with unicast DLIDs greater than this value are discarded by the switch. This component applies only to switches that implement linear forwarding tables and is ignored by switches that implement random forwarding tables.
What is ibSmSwitchInfoLinearFdbTop?
The top of the linear forwarding table: packets with unicast DLIDs above this value are discarded, and switches using random tables ignore it. If it is too low, nodes with higher LIDs become unreachable.
Examples
Walk all instances (SNMPv2c):
