# Release Features(s)

* TBD
* <b><i>Ixia-C, Ixia Chassis & Appliances(Novus, AresOne)</i></b>: Support added for GUEv1 IPv4/v6 over UDP traffic.
```go
f1Ip1 := f1.Packet().Add().Ipv4()​
f1Ip1.Src().SetValue("1.1.1.1")​
f1Ip1.Dst().SetValue("1.1.1.2")​
​
f1Udp := f1.Packet().Add().Udp()​
f1Udp.SrcPort().SetValue(30000)​
f1Udp.DstPort().SetValue(6080)​
// IPv4 Over UDP​
f1Ip2 := f1.Packet().Add().Ipv4()​
f1Ip2.Src().SetValues([]string{​
"2.2.2.1",​
"2.2.2.2",​
"2.2.2.3",​
"2.2.2.4",​
})​
f1Ip2.Dst().SetValue("3.3.3.1")​
```

* <b><i>Ixia-C, Ixia Chassis & Appliances(Novus, AresOne)</i></b>: Support added for MPLS Over UDP traffic.
```go
//udp Dst port as 6635​
f1Udp := f1.Packet().Add().Udp()​
f1Udp.DstPort().SetValue(6635)​
f1Udp.SrcPort().SetValue(65530)​
//mpls over udp​
f1Mpls1 := f1.Packet().Add().Mpls()​
f1Mpls1.Label().SetValue(10001)​
f1Mpls1.BottomOfStack().SetValue(0)
f1Mpls2 := f1.Packet().Add().Mpls()​
f1Mpls2.Label().SetValue(10011)​
//ipv4 over mpls over udp​
f1MplsIp := f1.Packet().Add().Ipv4()​
f1MplsIp.Dst().SetValues([]string{​
"20.20.20.1",​
"20.20.20.2",​
"20.20.20.3",​
"20.20.20.4",​
})​
f1MplsIp.Src().SetValue("10.10.10.1")
```
Note: MPLS Over UDP with DTLS is not supported.

* <b><i>Ixia-C, Ixia Chassis & Appliances(Novus, AresOne)</i></b>: Egress tracking is now supported for UDP, TCP, MPLS and IPv4/v6 inner header fields when encapsulated inside UDP.
```go
//egress tracking
f1.EgressPacket().Add().Ethernet()
f1.EgressPacket().Add().Ipv4()
f1.EgressPacket().Add().Udp()
f1.EgressPacket().Add().Mpls()
mplsLabelTracking := f1.EgressPacket().Add().Mpls()
tr1 := mplsLabelTracking.Label().MetricTags().Add()
tr1.SetName("MplsLabelEgressTracking")
tr1.SetOffset(17)
tr1.SetLength(3)
```

### Bug Fix(s)
* TBD

* <b><i>Ixia Chassis & Appliances(Novus, AresOne)</i></b>: Issue is fixed where configs with RSVP and multiple Loopback interfaces was throwing error similar to `"loopback p2.d2.lo and lo.d not compatible"` on `set_config`.
* <b><i>Ixia-C, Ixia Chassis & Appliances(Novus, AresOne)</i></b>: Issue where config with large number of route ranges was causing error similar to `"grpc: received message larger than max (114278270 vs. 104857600)"` on `set_config` is fixed by increasing the default gRPC receive buffer size to 1GB.
- Note that for Ixia Chassis & Appliances(Novus, AresOne) the buffer can now be controlled by setting the environment variable of `keng-controller` as given below.
```sh
command:
...
- "--grpc-max-msg-size"​
- "500"
```
* <b><i>Ixia Chassis & Appliances(Novus, AresOne)</i></b>: Issue is fixed where `set_config` was throwing error if Traffic Engineering was enabled for ISIS interface, but Priority BandWidths were not explicitly specified.
* <b><i>Ixia-C, UHD400</i></b>: Issue is fixed where DHCPv4 was intermittently crashing on stop.
* <b><i>Ixia Chassis & Appliances(Novus, AresOne)</i></b>: Issue is fixed where OSPFv2 Router Ids were not getting set properly when multiple OSPFv2 Routers were configured on
a port.
