Hi.

i am trying to configure gnmic as listen to work with a cisco asr.

this is the command i use

gnmic --address 0.0.0.0:32767 --insecure --log-file /var/log/gnmic/gnmic-PE-CISCO.log --format event --encoding event --no-prefix --debug listen

and this is the resulting log

Why is it generating this error?

what am I doing wrong?

The listen command is intended to be used with Nokia SROS dial-out only.
gNMIc does not support any other vendor proprietary dialout service. but it does support openconfig dial-out based on grpc-tunnel.

btw, this repo will be archived soon, the project moved to https://github.com/openconfig/gnmic
