|
57 | | -* <b><i>Ixia Chassis & Appliances(Novus, AresOne)</i></b>: Support added for ISIS Simulated Topology. [More Details](https://github.com/open-traffic-generator/models/pull/327) |
58 | | - - Configuration for ISIS attributes for newly introduced simulated routers are identical to configuration for currently supported directly connected emulated routers. |
59 | | - - `devices[i].ethernets[j].connection.simulated_link` is introduced to create a simulated ethernet connection to build a Simulated Topology. |
| 40 | +* <b><i>Ixia-C, Ixia Chassis & Appliances(Novus, AresOne)</i></b>: Support added for GRE header in traffic flows. |
60 | 41 | ```go |
61 | | - simulatedRouterEthernet := simulatedRouter.Ethernets().Add(). |
62 | | - SetName("simRtrEth"). |
63 | | - SetMac("00:00:11:02:02:02") |
64 | | - simulatedRouterEthernet.Connection().SimulatedLink().SetRemoteSimulatedLink("connRtrSimEth") |
65 | | - |
66 | | - connectedRouterSimulatedEthernet := connectedRouter.Ethernets().Add(). |
67 | | - SetName("connRtrSimEth"). |
68 | | - SetMac("00:00:01:01:01:01") |
69 | | - connectedRouterSimulatedEthernet.Connection().SimulatedLink().SetRemoteSimulatedLink("simRtrEth") |
| 42 | + flow1 := config.Flows().Add() |
| 43 | + ... |
| 44 | + gre := flow1.Packet().Add().Gre() |
| 45 | + ... |
70 | 46 | ``` |
71 | | - Note: `get_metrics/states` APIs are only applicable for the connected emulated routers and not for the simulated routers. |
| 47 | + Note: By default the correct GRE Protocol value will be set automatically depending on next header eg. IPv4/v6. |
72 | 48 |
|
73 | | -* <b><i>Ixia-C, UHD400, Ixia Chassis & Appliances(Novus, AresOne)</i></b>: Support added for fetching `lldp_neighbors[i].custom_tlvs[j].information` as hex bytes using `get_states` API. [More details](https://github.com/open-traffic-generator/models/pull/392) |
74 | 49 |
|
75 | 50 | ### Bug Fix(s) |
76 | | -* <b><i>Ixia Chassis & Appliances(Novus, AresOne)</i></b>: Issue is fixed where for certain scenarios such as retrieving large control capture buffer or fetching `get_metrics/states` for large amount of data results in errors similar to <i>"grpc: received message larger than max (7934807 vs. 4194304)"</i>. |
77 | | - - For such scenarios note that the grpc receive buffer on the client should also be locally increased if necessary from default value of 4 MB. |
| 51 | +* <b><i>Ixia Chassis & Appliances(Novus, AresOne)</i></b>: Issue is fixed where fetching ISIS learned information using `get_states` would sometimes fail with a error <i>Cannot clear data while transfer is in progress - data would be inconsistent</i>. |
| 52 | + |
| 53 | +* <b><i>Ixia-C</i></b>: Issue is fixed where ARP/ND resolution was failing for LAG configurations with a mix of Loopback and connected interfaces. |
| 54 | + |
| 55 | +* <b><i>Ixia-C</i></b>: Issue is fixed where on fetching BGP/BGP+ learned prefix information using `get_states` would return an incorrect prefix in certain scenarios. This was more likely to happen for IPv6 prefixes. |
| 56 | + |
| 57 | +* <b><i>Ixia-C, UHD400</i></b>: Issue is fixed where if the DHCPv6 client type is configured as IANAPD, DHCPv6 Server `get_states` doesn't show IAPD addresses. |
78 | 58 |
|
79 | | -* <b><i>Ixia-C</i></b>: Issue is fixed for LLDP where, when multiple custom tlvs are configured to be sent, sometimes the bytes in the `information` field in the outgoing LLDP PDUs were corrupted. |
| 59 | +* <b><i>UHD400</i></b>: Issue is fixed where Auto MAC resolution was not working properly for multinic scenarios such as LAG, resulting in flows being transmitted with dest MAC as 00:00:00:00:00:00 and DUT not forwarding these packets. |

82 | 62 | #### Known Issues |
83 | | -* <b><i>Ixia-C, UHD400</i></b>: When the DHCPv6 client type is configured as IANAPD, DHCPv6 Server `get_states` doesn't show IAPD addresses |
84 | 63 | * <b><i>Ixia-C, UHD400</i></b>: When DHCPv6 Server is configured with multiple pools, The DHCPv6 clients are not accepting addresses from different pools. |
85 | 64 | * <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. |
86 | 65 | * <b><i>Ixia Chassis & Appliances(Novus, AresOne)</i></b>: `StartProtocols`/`set_control_state.protocol.all.start` can get stuck till the time all DHPCv4/v6 clients receive the leased IPv4/v6 addresses from the DHCPv4/v6 server/relay agent. This may result in getting `"context deadline exceeded"` error in the test program. |
