When setting both mtu and ipv4 address on interface in same gNMI request, mtu is not set, but address is.

[seiferteric]

The request looks like this:

{
  "openconfig-interfaces:config": {
    "description": "lab1-ed001:Eth10/1",
    "mtu": 9000,
    "name": "Ethernet4"
  },
  "openconfig-interfaces:name": "Ethernet4",
  "openconfig-interfaces:subinterfaces": {
    "subinterface": [
      {
        "config": {
          "description": "lab1-ed001:Eth10/1",
          "enabled": true,
          "index": 0
        },
        "index": 0,
        "openconfig-if-ip:ipv4": {
          "addresses": {
            "address": [
              {
                "config": {
                  "ip": "10.11.2.1",
                  "prefix-length": 31
                },
                "ip": "10.11.2.1"
              }
            ]
          }
        }
      }
    ]
  }
}

The path is: openconfig-interfaces:interfaces/interface[name=Ethernet4]

After the update is ran, the ip address is set, but the mtu is not. If I set the mtu separately, the mtu is set correctly.

Actually, just setting mtu alone from the top level interface does not work. It only works when I specify the full path like: /openconfig-interfaces:interfaces/interface[name=Ethernet4]/config/mtu and a payload like:

{
  "mtu": 9000
}

@justinejose91 is this operation supported? Is the request crafted correctly?

I will have a look at this one. I will add my analysis.
