@@ -33,6 +33,7 @@ The following arguments are supported:
 * `name` - (Required) The name for the virtual interface.
 * `vlan` - (Required) The VLAN ID.
 * `amazon_address` - (Optional) The IPv4 CIDR address to use to send traffic to Amazon. Required for IPv4 BGP peers.
+* `mtu` - (Optional) The maximum transmission unit (MTU) is the size, in bytes, of the largest permissible packet that can be passed over the connection. The MTU of a virtual private interface can be either 1500 or 9001 (jumbo frames). Default is 1500. `jumbo_frame_capable` will be exported as `true` if jumbo frames have been enabled.
 * `bgp_auth_key` - (Optional) The authentication key for BGP configuration.
 * `customer_address` - (Optional) The IPv4 CIDR destination address to which Amazon should send traffic. Required for IPv4 BGP peers.
 * `dx_gateway_id` - (Optional) The ID of the Direct Connect gateway to which to connect the virtual interface.
