Description: This object controls whether ICMP issues Destination Unreachable packets on this port.
What is a3IPicmpGenDestUnreach?
Controls whether the port generates ICMP Destination Unreachable messages when packets cannot be delivered. Enabling this provides diagnostic feedback to senders when routes fail or services stop. Disabling it silently drops unreachable packets, useful for preventing network scanning.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.43.2.6.18.1.3 snmpwalk -v2c -c public <target> A3COM-IPEXTNS-R5-MIB::a3IPicmpGenDestUnreach
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.43.2.6.18.1.3.1 snmpget -v2c -c public <target> A3COM-IPEXTNS-R5-MIB::a3IPicmpGenDestUnreach.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.43.2.6.18.1.3.1 i <value>
