What is onuIpHostSecondaryDNS?
This is the secondary (backup) DNS server address configured for the ONU's host/management interface, used if the primary DNS server in onuIpHostPrimaryDNS is unreachable. Admins set it for DNS redundancy on the ONU's management path. For example, its absence would mean a single DNS server outage breaks the ONU's ability to resolve hostname-based management services.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.17409.2.8.4.3.1.8 snmpwalk -v2c -c public <target> NSCRTV-FTTX-GPON-MIB::onuIpHostSecondaryDNS
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.17409.2.8.4.3.1.8.1 snmpget -v2c -c public <target> NSCRTV-FTTX-GPON-MIB::onuIpHostSecondaryDNS.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.17409.2.8.4.3.1.8.1 a <value>
