Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.15.2.3.1.22
snmpwalk -v2c -c public <target> MSTP-MIB::swMSTPInstTopChangesCount

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.15.2.3.1.22.1
snmpget -v2c -c public <target> MSTP-MIB::swMSTPInstTopChangesCount.1
