Neutron agents are discovered by the neutron-server service when they are first activated, and these can be managed with the following commands:
agent-deleteagent-listagent-showagent-update
To schedule or unschedule a network to or from a DHCP agent or to determine a network to DHCP agent association, use the following commands:
dhcp-agent-list-hosting-netdhcp-agent-network-adddhcp-agent-network-removenet-list-on-dhcp-agent
