# Note related to use of index `1` of entPhysicalTable columns:
# Based on snmpwalks of Arista, the main/chassis hardware have the index `1`
# Librennms is also using index `1`: https://github.com/librenms/librenms/blob/1ac60e3b1d90616119f3c4adc28213e3c35c2477/includes/definitions/discovery/arista_eos.yaml#L4
