# Jumbo Frame Support and Packet Filtering

**Jumbo Frame Support on MCR** – A new field `ipMtu` has been added to the following endpoints which allows you to set the largest size (in bytes) of an IP packet that can be sent over the connected VXC.

* `POST /v3/networkdesign/validate`
* `POST /v3/networkdesign/buy`
* `PUT /v3/product/vxc/{uid}`

**Invoice Endpoint Improvements** – The invoicing endpoints have been updated to change the Invoice Charge From/To date fields to reflect the time period to which the ETF applies - the ETF duration.

**Packet Filtering on MCR Endpoints** – New endpoints have been created to manage MCR packet filters via the API. New fields have also been added to the VXC create/update endpoint data within the interfaces object to define packet filters for a VXC (`packetFilterIn`/`packetFilterOut`).

* `GET /v2/product/mcr2/{productUid}/packetFilter/{packetFilterId}` – MCR Packet Filter Details
* `GET /v2/product/mcr2/{productUid}/packetFilters` – MCR Packet Filter Summary List
* `POST /v2/product/mcr2/{productUid}/packetFilter` – Create MCR Packet Filter
* `PUT /v2/product/mcr2/{productUid}/packetFilter/{packetFilterId}` – Update MCR Packet Filter
* `DEL /v2/product/mcr2/{productUid}/packetFilter/{packetFilterId}` – Delete MCR Packet Filter

**Fixed** – The `/v2/products` endpoint was taking up to 4 minutes to respond for Google inc. This has now reduced significantly to around 50 seconds.
