NSX Advanced Load Balancer DNS can host manual static DNS entries. For a given FQDN, the user can configure an A, SRV, or CNAME record to be returned. This is accomplished through the NSX Advanced Load Balancer CLI as documented in this article.
The configure virtualservice dns-vs command shows there is already an existing static custom A record for FQDN ggg.avi.local.
: < configure virtualservice dns-vs Updating an existing object. Currently, the object is: +----------------------------------+--------------------------------------+ | Field | Value | +----------------------------------+--------------------------------------+ | uuid | virtualservice-bc7c7fc6-583e-4335-8d33-ec4670771a85 | | name | dns-vs | | ip_address | 10.90.12.200 | | enabled | True | | services[1] | | | port | 53 | | enable_ssl | False | | port_range_end | 53 | | application_profile_ref | System-DNS | | network_profile_ref | System-UDP-Per-Pkt | | se_group_ref | Default-Group | | east_west_placement | False | | scaleout_ecmp | False | | active_standby_se_tag | ACTIVE_STANDBY_SE_1 | | flow_label_type | NO_LABEL | | static_dns_records[1] | | | fqdn[1] | ggg.avi.local | | type | DNS_RECORD_A | | ip_address[1] | | | ip_address | 1.1.1.1 | +----------------------------------+--------------------------------------+
Another similar custom A record can be added:

The above command sequence will create a static entry for the FQDN
abc.avi.local on virtual service
dns-vs. This can also be confirmed from the GUI under
as illustrated below.
Note:
For servers added by domain name, manual changes to the resolved server’s IP addresses are overwritten automatically.
