What is hmIGMPSnoopUnknownMode?

This object determines how the network switch handles multicast packets from sources it doesn't recognize, with options to discard, flood, or query known multicast ports. Switch administrators use it to tune multicast behavior and prevent unknown traffic from overwhelming the network or flooding all ports. The setting balances multicast service availability against network bandwidth protection.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.248.14.2.10.1.2.3
snmpwalk -v2c -c public <target> HMPRIV-MGMT-SNMP-MIB::hmIGMPSnoopUnknownMode

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.248.14.2.10.1.2.3.1
snmpget -v2c -c public <target> HMPRIV-MGMT-SNMP-MIB::hmIGMPSnoopUnknownMode.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.248.14.2.10.1.2.3.1 i <value>

Start monitoring Hirschmann modular industrial Ethernet switch (e.g. RSPE-Expandable/MACH104 series) with a free 30-day trial of IPNetwork Monitor. Create custom SNMP monitor using the HMPRIV-MGMT-SNMP-MIB::hmIGMPSnoopUnknownMode OID value, configure state conditions and alerts, and monitor any Hirschmann modular industrial Ethernet switch (e.g. RSPE-Expandable/MACH104 series) from a single console.
