What is mitelDnsGrpFilterEnabled?
mitelDnsGrpFilterEnabled toggles DNS security filtering, and when enabled the device filters (rejects) DNS queries that don't originate from localhost. Admins enable this to lock down the device's DNS service so it only answers its own internal lookups rather than acting as an open resolver reachable by other hosts on the network. For example, setting this to enabled(1) on a device that shouldn't be providing DNS service to the broader LAN prevents it from being used as an open DNS relay.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1027.4.8.1.1.3.7 snmpwalk -v2c -c public <target> MITEL-DNSGROUP-MIB::mitelDnsGrpFilterEnabled
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.1027.4.8.1.1.3.7.1 snmpget -v2c -c public <target> MITEL-DNSGROUP-MIB::mitelDnsGrpFilterEnabled.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.1027.4.8.1.1.3.7.1 i <value>
