hmIGMPSnoopUnknownLookupInterval
Module: HMPRIV-MGMT-SNMP-MIB
OID (symbolic): HMPRIV-MGMT-SNMP-MIB::hmIGMPSnoopUnknownLookupInterval
OID (numeric): 1.3.6.1.4.1.248.14.2.10.1.2.5
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: The frequency at which Unknown Multicast Groups dynamically learned with traffic snooping are traffic checked by the switch in seconds. So this is the time between periodic traffic checking in which unknown multicast groups being aged on the switch when it is acting as Trafficsnooper. Large values lead to traffic checking less often. The default is 125 seconds and the range is 2 to 3599 seconds.
What is hmIGMPSnoopUnknownLookupInterval?
This OID stores the interval in seconds between traffic checks for unknown multicast group streams on network switches. It controls how often the switch refreshes its knowledge of which multicast groups have active traffic. An operator would increase this value on a busy network to reduce CPU load from frequent checks, or decrease it to detect group changes faster.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.248.14.2.10.1.2.5 snmpwalk -v2c -c public <target> HMPRIV-MGMT-SNMP-MIB::hmIGMPSnoopUnknownLookupInterval
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.248.14.2.10.1.2.5.1 snmpget -v2c -c public <target> HMPRIV-MGMT-SNMP-MIB::hmIGMPSnoopUnknownLookupInterval.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.248.14.2.10.1.2.5.1 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::hmIGMPSnoopUnknownLookupInterval 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.
