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)
