Module: CMC-MIB
OID (symbolic): CMC-MIB::cmcIpFiltErrMsg
OID (numeric): 1.3.6.1.4.1.44.2.1.4.5.1.11

Description: Configuration object used to control the transmission of ICMP error messages when datagrams are administratively filtered.
What is cmcIpFiltErrMsg?
This INTEGER (enable/disable) controls whether the system sends ICMP error messages back to a sender whose datagrams are administratively filtered. An admin disables this when they don't want to reveal to blocked senders that their traffic was filtered, or enables it for normal ICMP feedback behavior. For example, an operator trying to silently drop traffic from a suspected attacker without tipping them off would set cmcIpFiltErrMsg to disable(2).
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.44.2.1.4.5.1.11 snmpwalk -v2c -c public <target> CMC-MIB::cmcIpFiltErrMsg
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.44.2.1.4.5.1.11.1 snmpget -v2c -c public <target> CMC-MIB::cmcIpFiltErrMsg.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.44.2.1.4.5.1.11.1 i <value>
