Description:
 def evpn_instance_mac_timer_max_count(self, **kwargs):
 """ Add "Duplicate MAC max count" under evpn instance. Args: evpn_instance_name: Instance name for evpn max_count: Duplicate MAC max count. enable (bool):
 If target community needs to be enabled or disabled.Default:``True``. get (bool) : Get config instead of editing config. (True, False) rbridge_id (str):
 rbridge-id for device. Only required when type is `ve`. callback (function):
 A function executed upon completion of the method. The only parameter passed to `callback` will be the ``ElementTree`` `config`. Returns: Return value of `callback`. Raises: KeyError: if 'evpn_instance_name' is not passed. ValueError: if 'evpn_instance_name' is invalid. Examples: Traceback (most recent call last):
