What is hm2DnsCacheFlushAction?
This read-write, deprecated HmActionValue object flushes the DNS cache when set to action, automatically resetting itself to noop afterward; it has been replaced by hm2DevMgmtActionFlushDnsClientCache/hm2DevMgmtActionFlushDnsCachingServerCache. An admin triggers this to force fresh DNS lookups after changing upstream DNS records, though new configurations should use the replacement objects instead. For example, an admin sets this to action after updating a DNS record upstream, to immediately clear any stale cached entry on this device.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.248.11.90.1.2.2 snmpwalk -v2c -c public <target> HM2-DNS-MIB::hm2DnsCacheFlushAction
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.248.11.90.1.2.2.1 snmpget -v2c -c public <target> HM2-DNS-MIB::hm2DnsCacheFlushAction.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.248.11.90.1.2.2.1 s <value>
