Node type: OBJECT-TYPE
Type: InetAddressIPv4
Access: read-only
Description: Cisco UCS vnic:IPv4IscsiAddr:primDns managed object property
What is cucsVnicIPv4IscsiAddrPrimDns?
This OID returns the primary DNS server address used by an IPv4 iSCSI boot address during iSCSI boot, carried as an IPv4 address. An admin checks this when an iSCSI-booting server fails to resolve a hostname-based target early in boot, since this value (not the OS's own DNS settings) governs name resolution at that stage. For example, if the primary DNS server listed here is unreachable from the boot network, iSCSI boot on this IPv4 iSCSI boot address can stall or fail before the OS ever loads its own network stack.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.719.1.53.36.1.6 snmpwalk -v2c -c public <target> CISCO-UNIFIED-COMPUTING-VNIC-MIB::cucsVnicIPv4IscsiAddrPrimDns
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.9.9.719.1.53.36.1.6.1 snmpget -v2c -c public <target> CISCO-UNIFIED-COMPUTING-VNIC-MIB::cucsVnicIPv4IscsiAddrPrimDns.1
