What is hm2EtherNetIPMcastStartAddress?

The first multicast IPv4 address in the range the device allocates from when hm2EtherNetIPMcastAllocControl is set to defined(1); combined with hm2EtherNetIPMcastCount it defines the full reserved multicast block for EtherNet/IP I/O traffic.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.248.11.101.1.3.3.4
snmpwalk -v2c -c public <target> HM2-INDUSTRIAL-PROTOCOLS-MIB::hm2EtherNetIPMcastStartAddress

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.248.11.101.1.3.3.4.1
snmpget -v2c -c public <target> HM2-INDUSTRIAL-PROTOCOLS-MIB::hm2EtherNetIPMcastStartAddress.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.248.11.101.1.3.3.4.1 s <value>

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> hm2EtherNetIPMcastStartAddress.1
