I am trying to setup the Enterprise agent on our C9407 switch. We would like to be able to monitor devices on different vlans. I can access devices on the first vlan but the others it gives me an error.
I have the following Network Interfaces setup.

I was able to add devices on subnet 172.29.0.0/21 but not the other two.
When I ping 172.29.0.20 from the switch I get a response. When I try pinging the other two I get no reponse.
I am not sure what I am missing here. I followed this document under
Multi-Interface Support for Cisco Catalyst 9000 Switches
Installing Enterprise Agents on Cisco Switches with Docker - ThousandEyes Documentation
