Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.45.5.5.1.1.19
snmpwalk -v2c -c public <target> NORTEL-NETWORKS-MULTIPLE-SPANNING-TREE-MIB::nnMstTxHoldCount

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.45.5.5.1.1.19.1
snmpget -v2c -c public <target> NORTEL-NETWORKS-MULTIPLE-SPANNING-TREE-MIB::nnMstTxHoldCount.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.45.5.5.1.1.19.1 i <value>
