Open-config Terminal Devices RPC Payload failed to take values for "rateclass" "trib_protocol" and "Logical_channel_type"

[vinogovi]

While trying to configure Logical channel in Terminal devices

1. RPC payload failed to take the values for "logical_channel_type", "rate_class", "trib_protocol".

2. while trying through CLI getting below error.

```ssh

"RP/0/RP0/CPU0:ios(config-logical-channel)#logical-channel-type ethernet

Failed to commit one or more configuration items during a pseudo-atomic operation. All changes made have been reverted. Please issue 'show configuration failed [inheritance]' from this session to view the errors"

```

Code snip:

```python

from ydk.models.openconfig import openconfig_terminal_device as td

def logical_channels_config(self):

       ab = td.TerminalDevice()

#       ac = ty.LoopbackModeType()

       lc =ab.LogicalChannels.Channel()

       lc.index = 1

       lc.config.index = lc.index

       lc.index = lc.config.index

       lc.config.description = "configuring logical channel"

#       lc.config.admin_state =

#       lc.config.loopback_mode = none

       lc.config.logical_channel_type = "Ethernet"

       lc.config.rate_class = "10G"

#       lc.config.trib_protocol = "Prot_10Ge_WanIdentity"

       ab.logical_channels.channel.append(lc)

       pdb.set_trace()

       self.crudservice.create(self.provider, ab)

```

Vinoth,

This doesn't look like any problem with the YDK, but a problem either with what you have tried to configure or with the mapping of that configuration to the XR native model. Suggest you get the debug output from the YDK application and engage with the team building the optical mapping.

Cheers,

Einar

Hi, Vinoth.

Looks like you're trying to configure a slice in NCS1002 (10G client, right?).

Configuration should include not just terminal-devices, but some other models and there is an internal interdependence (you will need to commit them all together or NCS1k won't accept the change).

I'm almost done with full config using YDK and it will be posted very soon (XML structure is also there). It will be done for all 100G and 10G client modes (5 basic examples in YDK-python, that you can enhance and use as you want).

While waiting, please, have a look here: https://xrdocs.github.io/programmability/tutorials/2017-08-22-ncs1002-configuration-automation-overview/ , it provides some basic background of how to use OpenConfig models with NCS1002.

Regards,

Viktor
