hm2EtherNetIPMcastAllocControl
Module: HM2-INDUSTRIAL-PROTOCOLS-MIB
OID (symbolic): HM2-INDUSTRIAL-PROTOCOLS-MIB::hm2EtherNetIPMcastAllocControl
OID (numeric): 1.3.6.1.4.1.248.11.101.1.3.3.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Controls how the device shall allocate IP multicast addresses. A value of 0 means multicast addresses shall be generated using the default allocation algorithm. A value of 1 means multicast addresses shall be allocated according to the values specified in Num Mcast and Mcast Start Addr. The value 2 is reserved.
What is hm2EtherNetIPMcastAllocControl?
Chooses how the device allocates multicast addresses for EtherNet/IP I/O connections: default(0) uses the built-in algorithm, defined(1) uses the explicit range set via hm2EtherNetIPMcastCount/hm2EtherNetIPMcastStartAddress, and reserved(2) is unused. An admin sets defined(1) when multicast addressing needs to be predictable for network planning.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.248.11.101.1.3.3.2 snmpwalk -v2c -c public <target> HM2-INDUSTRIAL-PROTOCOLS-MIB::hm2EtherNetIPMcastAllocControl
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.248.11.101.1.3.3.2.1 snmpget -v2c -c public <target> HM2-INDUSTRIAL-PROTOCOLS-MIB::hm2EtherNetIPMcastAllocControl.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.248.11.101.1.3.3.2.1 i <value>
