globalRTTPortDiscovery
Module: F5-3DNS-MIB
OID (symbolic): F5-3DNS-MIB::globalRTTPortDiscovery
OID (numeric): 1.3.6.1.4.1.3375.1.2.1.1.1.40
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: Indicates whether the load-balancing DNS server uses the discovery factory to find an alternate port to be used by the probing factory, if probing on port 53 fails.
What is globalRTTPortDiscovery?
Reports whether 3DNS automatically searches for a working alternate port when probing on the default port 53 fails, rather than simply marking the target unreachable. Enabling it lets a service running DNS-style health checks on a non-standard port still be probed successfully.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.3375.1.2.1.1.1.40 snmpwalk -v2c -c public <target> F5-3DNS-MIB::globalRTTPortDiscovery
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.3375.1.2.1.1.1.40.1 snmpget -v2c -c public <target> F5-3DNS-MIB::globalRTTPortDiscovery.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> globalRTTPortDiscovery.1
