# Usage:
#   gnmic subscribe --config /path/to/gnmic.yaml
#
# Test connectivity first:
#   gnmic -a 172.16.0.1:6030 -u admin -p admin --insecure capabilities
#
# Debug subscriptions:
#   gnmic -a 172.16.0.1:6030 -u admin -p admin --insecure \
#     subscribe --path /interfaces/interface/state --stream-mode sample --sample-interval 10s
