What is cntVL15Drop?

Cumulative count of dropped frames on VL15, the InfiniBand virtual lane reserved exclusively for subnet management traffic. Drops here can mean the subnet manager is losing control-plane messages to or from this port, which is more serious than ordinary data-lane drops.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.33049.2.2.1.2.1.1.16
snmpwalk -v2c -c public <target> MELLANOX-MIB::cntVL15Drop

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.33049.2.2.1.2.1.1.16.1
