cisco.cml.cml_lab_facts and cisco.cml.inventory not returning i"pv4_addresses" data

[ashwini-mhatre]

OS / ENVIRONMENT

CML version - 2.5.1
virl2-client-2.6.1

STEPS TO REPRODUCE

when using cisco.cml.cml_lab_facts and cisco.cml.inventory playbooks, The resulted facts doesn't have ipv4_address data:

we have two nodes in our topology:
1.nxos
2.external connector

On nxos we have configured ip address on management interface that should come as part of facts of nxos node. which is not coming.

IP address was configured via DHCP from the external connector.

And also the /labs/{ lab_id }/layer3_addresses endpoint also does not return this data.

R1(config)# show ip interface brief vrf management

@stevenca Could you please help us with this? Thank you!

The CML layer3_addresses endpoint can sometimes stop working and will cause the behavior you are seeing. Restarting the CML services will usually restore the L3 functionality.
