Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.562.36.2.1.115.16.100.1.1
snmpwalk -v2c -c public <target> Nortel-MsCarrier-MscPassport-VoiceNetworkingMIB::mscSigChanNcasDirection

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.562.36.2.1.115.16.100.1.1.1
snmpget -v2c -c public <target> Nortel-MsCarrier-MscPassport-VoiceNetworkingMIB::mscSigChanNcasDirection.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> mscSigChanNcasDirection.1
