mssql

Category with a list of MSSQL-related facts

mssql_version with a value of 15.0.4153.1

network_interfaces

List of facts related to network interfaces.

There are six facts for each interface: ipv6_addresses, ipv4_addresses, mac_address, mtu, state and type. The two address fields are comma-separated lists of IP addresses. The state field is either UP or DOWN. The type field is the interface type (ex: ether, loopback, bridge, etc.).

Each interface (ex: lo, em1, etc) is prefixed to the fact name. For example, em1’s mac address would be the fact named em1.mac_address.

Most network interface facts are compared to ensure they are equal across systems. However, ipv4_addresses, ipv6_addresses, and mac_address are checked to ensure they are different across systems. A subexception for lo should always have the same IP and mac address on all systems.
