# gNMIc configuration for Arista EVPN-VXLAN fabric
# Enhanced with VXLAN-specific telemetry via Vxlan1 interface
# Paths verified for Arista cEOS 4.35 compatibility
#
# Usage:
#   gnmic subscribe --config /path/to/gnmic.yaml
#
# Test connectivity:
#   gnmic -a 172.16.0.1:6030 -u admin -p admin --insecure capabilities
#
# Debug subscriptions:
#   gnmic -a 172.16.0.25:6030 -u admin -p admin --insecure \
#     get --path /interfaces/interface[name=Vxlan1]
