This PR changes the client get states to have lease time per iapd and ia address

This shows configuration of one dhcpv6 client and server in two different ports

The first eg is of a dhcpv6 client and the next of a dhcpv6 server

// Case-1: DHCPv6 Client // DHCPv6 Client is configured on connected interface.

Creating Ports

import otg api = otg.api(location="https://localhost/") config = api.config() p1 = config.ports.port(name='p1', location='172.17.0.2:50071')[-1]

Create DHCPv6 client running on connected interface port 1.

p1_d1 = config.devices.device(name='p1_d1')[-1]

p1_eth1 = p1_d1.ethernets.ethernet()[-1] p1_eth1.connection.port_name = p1.name p1_eth1.name = 'p1_eth1'

p1_eth1.mac = '64:00:00:00:00:01' p1_dhcp1 = p1_eth1.dhcpv6_interfaces.dhcpv6client(name = 'p1_dhcp1')[-1] print(config.serialize())

// Case-2: DHCPv6 Server.

Creating Ports

import otg api = otg.api(location="https://localhost/") config = api.config() p2 = config.ports.port(name='p2', location='172.17.0.3:50071')[-1]

Create ethernet and ipv6 running on connected ipv6 interface port 2.

p2_d1 = config.devices.device(name='p1_d1')[-1] p2_eth1 = p2_d1.ethernets.ethernet()[-1] p2_eth1.connection.port_name = p2.name p2_eth1.name = 'p1_eth1' p2_eth1.mac = '64:00:00:00:00:01' p2_ip1 = p2_eth1.ipv6_addresses.ipv6(name = 'p2_ip1', address = '2000:0:0:1::2', gateway = '2000:0:0:1::1')[-1]

Creating a DHCPv6 server on the connected interface port2. p2_dhcp1 = p2_d1.dhcp_server.ipv6_interfaces.v6(name='p2_dhcp1',ipv6_name=p2_ip1.name)[-1] p2_dhcp1_lease = p2_dhcp1.leases.lease()[-1] p2_dhcp1_lease_iatype = p2_dhcp1_lease.ia_type.choice="iapd" p2_dhcp1_lease.ia_type.iapd.start_prefix_address = "a1a1::0" p2_dhcp1_lease.ia_type.iapd.prefix_step = 1 print(config.serialize()) { "devices": [ { "ethernets": [ { "connection": { "choice": "port_name", "port_name": "p1" }, "dhcpv6_interfaces": [ { "name": "p1_dhcp1", "rapid_commit": false } ], "mac": "64:00:00:00:00:01", "mtu": 1500, "name": "p1_eth1" } ], "name": "p1_d1" } ], "ports": [ { "location": "172.17.0.2:50071", "name": "p1" } ] }
