macAddress

Validate that a string is a valid MAC address. Accepts colon-separated, dash-separated, and Cisco dot-separated formats — but the same separator must be used throughout.

Signature​

NguardValidators.String.macAddress: ValidatorFn

A parameterless validator — used directly without invocation.

Reactive forms​

import { FormControl } from '@angular/forms';
import { NguardValidators } from 'ng-nguard';

const address = new FormControl('', [NguardValidators.String.macAddress]);

Template-driven forms​

<input ngModel name="address" nguardMacAddress />

Error key​

{ macAddress: true }

Notes​

  • Accepted formats:
    • Colon-separated: 00:1B:44:11:3A:B7
    • Dash-separated: 00-1B-44-11-3A-B7
    • Cisco dot-separated: 001B.4411.3AB7
  • The separator must be consistent across all groups — 00:1B-44:11-3A:B7 fails.
  • Hex digits are case-insensitive.
  • Empty strings fail.
