ibIfPortStatVL15Dropped
Module: IB-IF-MIB
OID (symbolic): IB-IF-MIB::ibIfPortStatVL15Dropped
OID (numeric): 1.3.6.1.3.117.2.1.1.1.15
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: Number of incoming VL15 packets dropped due to resource limitations on the selected port (e.g., lack of buffers).
What is ibIfPortStatVL15Dropped?
This counter tracks incoming management traffic on virtual lane 15 that was dropped due to resource limitations such as insufficient buffers. Since VL15 carries InfiniBand subnet management traffic, dropped packets here can disrupt fabric management operations like subnet discovery or routing updates. An admin seeing this counter climb would investigate whether the port's management traffic buffering needs to be increased to avoid impacting subnet manager communication.
