Module: CNT251-MIB

OID (symbolic): CNT251-MIB::cnt2SysAdapterOsMajorVersion

OID (numeric): 1.3.6.1.4.1.333.2.5.1.11.1.12

Node type: OBJECT-TYPE

What is cnt2SysAdapterOsMajorVersion?

This read-only INTEGER reports the major version number of the operating system running on the adapter in this slot. An admin planning an OS upgrade rollout would check this value to know which adapters are already current and which still need updating. For example, an adapter reporting an older OS major version than the fleet standard would be prioritized for the next maintenance window.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.333.2.5.1.11.1.12
snmpwalk -v2c -c public <target> CNT251-MIB::cnt2SysAdapterOsMajorVersion

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.333.2.5.1.11.1.12.1
snmpget -v2c -c public <target> CNT251-MIB::cnt2SysAdapterOsMajorVersion.1
