mac

Checks that the value is a MAC address: six pairs of hex digits separated by : or by -. { mac: 64 } checks a 64-bit EUI-64 identifier: eight pairs.

Error codes: WRONG_MAC, FORMAT_ERROR

The same separator is used everywhere: 00:1A:2b:3c:4D:5e and 00-1a-2b-3c-4d-5e pass, 00:1a:2b-3c:4d:5e does not. Hex digits are case-insensitive, and the case of the input is kept in the output.

The argument is the number of bits:

Rule	Pairs	Example	Used for
`'mac'`, `{ mac: 48 }`	6	`00:1a:2b:3c:4d:5e`	MAC-48 / EUI-48: Ethernet, Wi-Fi, Bluetooth
`{ mac: 64 }`	8	`70-B3-D5-7E-D0-00-12-34`	EUI-64: LoRaWAN DevEUI and JoinEUI, IEEE 802.15.4 (Zigbee), IPv6 interface identifiers

{ dev_eui: ['required', { mac: 64 }] }

Any other number ({ mac: 32 }) is a schema error. Forms without separators (001a2b3c4d5e) and with dots (001a.2b3c.4d5e) do not pass: use hex with length_equal for them.
