## **Existing Port**

If you have an established cross connect to Zenlayer Cloud Networking offline before, you can select your existing port. If you don't, see the following steps to create a new one.

## **New Port**

If you do not have an existing port or it is not your desired one, you will need to create a new port.

Click **Create New Port** to create a new port.

1. Select the port location closest to your data center.
2. Select the port specification. 1 Gbps, 10 Gbps and 100 Gbps are supported.\ <img src="/files/BWTIZWYCb7GnrFL9mThK" alt="" data-size="line"><mark style="color:blue;">**Note**</mark>\ <mark style="color:blue;">To future-proof your business, a 10 Gbps above port rate is recommended.</mark>
3. Label your port for identification.
4. Enter the legal business name of the authorized party. You will receive an LOA (letter of authorization) that is used to establish your cross connect.

   * <mark style="color:blue;">The LOA will be emailed to you as an attachment 2 to 3 days after you submit your new port order. You can also download your LOA in the</mark> <mark style="color:blue;">**Port**</mark> <mark style="color:blue;">on zenConsole.</mark>
   * <mark style="color:blue;">The LOA will expire in 30 days. Please establish your cross connect as soon as possible.</mark>

## VLAN ID

Configure a VLAN ID, and data will be transmitted in the corresponding VLAN.\
The system will assign a VLAN ID by default. If you want to customize it, choose a VLAN ID within 2 to 3499.

## What to Do Next

Contact Zenlayer Support or your data center operator to establish a cross connect offline.
