| # Release Features(s) | ||
| * <b><i>Ixia Chassis & Appliances(Novus, AresOne)</i></b>: Support added for DHCPv4 Client and Server in control plane. [details](https://github.com/open-traffic-generator/models/pull/371) | ||
| - User will be the able to configure DHCPv4 Client and Server by the following code snippet. More comprehensive [B2B example](https://github.com/open-traffic-generator/featureprofiles/blob/dev-dhcp/feature/dhcp/dhcpv4_client_server_b2b_test.go) | ||
| ```go | ||
| // Configure a DHCP Client | ||
| dhcpclient := d1Eth1.Dhcpv4Interfaces().Add(). | ||
| SetName("p1d1dhcpv41") | ||
|
|
||
| dhcpclient.FirstServer() | ||
| dhcpclient.ParametersRequestList(). | ||
| SetSubnetMask(true). | ||
| SetRouter(true). | ||
| SetRenewalTimer(true) | ||
|
|
||
| // Configure a DHCP Server | ||
| d2Dhcpv4Server := d2.DhcpServer().Ipv4Interfaces().Add(). | ||
| SetName("p2d1dhcpv4server") | ||
|
|
||
| d2Dhcpv4Server.SetIpv4Name("p2d1ipv4").AddressPools(). | ||
| Add().SetName("pool1"). | ||
| SetLeaseTime(3600). | ||
| SetStartAddress("100.1.100.1"). | ||
| SetStep(1). | ||
| SetCount(1). | ||
| SetPrefixLength(16).Options().SetRouterAddress("100.1.0.1").SetEchoRelayWithTlv82(true) | ||
| ``` | ||
|
|
||
| * <b><i>Ixia Chassis & Appliances(Novus, AresOne)</i></b>: gNMI support added to fetch DHCPv4 Client and Server statistics. | ||
| - [DHCPv4 Client](https://github.com/open-traffic-generator/models-yang/blob/main/artifacts/open-traffic-generator-dhcpv4client.txt) | ||
|
|
||
| ```gNMI | ||
| # Combined metrics and states information | ||
| dhcpv4-clients/dhcpv4-client[name=clientName]/state | ||
| # Metrics information | ||
| dhcpv4-clients/dhcpv4-client[name=clientName]/state/counters | ||
| # States information | ||
| dhcpv4-clients/dhcpv4-client[name=clientName]/state/interface | ||
| ``` | ||
| - [DHCPv4 Server](https://github.com/open-traffic-generator/models-yang/blob/main/artifacts/open-traffic-generator-dhcpv4server.txt) | ||
|
|
||
| ```gNMI | ||
| # Combined metrics and states information | ||
| dhcpv4-servers/dhcpv4-servers[name=serverName]/state | ||
| # Metrics information | ||
| dhcpv4-servers/dhcpv4-servers[name=serverName]/state/counters | ||
| # States information | ||
| dhcpv4-servers/dhcpv4-servers[name=serverName]/state/leases (For now it will return empty responses.) | ||
| ``` | ||
| Note: Support for `GetStates`/`dhcpv4-servers/dhcpv4-servers[name=serverName]/state/leases` of DHCP Server will be provided in subsequent release. | ||
|
|
||
| ### Bug Fix(s) | ||
| * <b><i>UHD400</i></b>: An issue has been detected whereby some internal certificates used in the UHD400 solution has expired. | ||
| The most common manifestation of this is that despite proper ARP resolution, packets of `flows` of type `device` might not get forwarded by the DUT, resulting in 0 `rx` statistics. | ||
| This issue is visible for UHD400/ixia-c releases up to `v1.5.0-1`. | ||

|
|
||
| #### Known Issues | ||
| * <b><i>Ixia Chassis & Appliances(Novus, AresOne)</i></b>: `set_control_state.protocol.all.start` can get stuck till the time all DHPCv4 clients receive the leased IPv4 addresses from the DHCPv4 server/relay agent. This may result in getting `"context deadline exceeded"` error in the test program. | ||
| * <b><i>Ixia Chassis & Appliances(Novus, AresOne)</i></b>: If `keng-layer23-hw-server` version is upgraded/downgraded, the ports which will be used from this container must be rebooted once before running the tests. | ||
| * <b><i>UHD400</i></b>: Packets will not be transmitted if `flows[i].rate.pps` is less than 50. | ||
| * <b><i>UHD400</i></b>: `values` for fields in flow packet headers can be created with maximum length of 1000 values. | ||
| * <b><i>Ixia-C</i></b>: Flow Tx is incremented for flow with tx endpoints as LAG, even if no packets are sent on the wire when all active links of the LAG are down. | ||
| * <b><i>Ixia-C</i></b>: Supported value for `flows[i].metrics.latency.mode` is `cut_through`. | ||
| * <b><i>Ixia-C</i></b>: The metric `loss` in flow metrics is currently not supported. | ||
| * <b><i>Ixia-C</i></b>: When flow transmit is started, transmission will be restarted on any existing flows already transmitting packets. |
