Enabling DHCP

Description

This article describes how to set IP addresses as either static or DHCP for a Cloudvue Gateways onboard NICs.

Product

Cloudvue Gateway

Prerequisites

Port #1 “NET” is connected to a network with internet access
The Cloudvue Gateway has be registered

Solutions

NOTE: Network Settings can only be viewed, not changed from cloudvue.com

Local Cloudvue

Open a web browser from a machine connected to the same network as the Cloudvue Gateway
Go to the LAN IP address of the Cloudvue Gateway for example http://192.168.1.180
- Note: See Knowledge Base Article #15509 “Finding Cloudvue Gateway IP Addresses” for more details about finding IP Addresses
Login to the Local Cloudvue instance
From the Navigation bar select Live
Expand Video Devices
Select the Cloudvue Gateway
From the Navigation bar select Settings
Select the Settings tab
Under Network Settings
- PORT 1 “LAN”
  - This is the NIC labeled “NET” on the gateway and should be connected to the customers local area network
  - It can be configured to either obtain an IP address dynamically “DHCP” or be assigned a Static IP
  - DHCP (Default)
    - Tick DHCP
  - STATIC
    - Tick Static
    - Enter the desired IP address
    - Enter a Subnet Mask
    - Enter the IP address for DNS Server 1
    - Enter the IP address for DNS Server 2
  - Save the Changes
- PORT 2 “Cameras”
  - This NIC is labeled POE on the gateway and should be connected to the Camera Network
  - It is intended to function as a DHCP server and assign a dynamic IP address to connected cameras
  - However, you can choose to set to static and manually IP connected cameras
  - DHCP Server (Default)
    - Tick DHCP Server
  - Static
    - To change the networking number scheme from the default 192.168.20.1
    - Enter a new IP address
    - Enter a Subnet Mask
  - NOTE: After changing PORT 2, all devices plugged into this port will need to be rebooted.
- Once satisfied click SAVE to apply changes

Command Line

The overall process is
Establish an SSH connection to the Cloudvue Gateway
- Enter your machines sudo password
- Enter the smartvue SSH password found in the SSH Section for the device in Cloudvue Manager.
Using either nano or vi edit the file /etc/network/interfaces
Make the desired changes to any NIC to set for either static or dhcp
Save the changes and exit the editor
Down and up the NICs which were changed to apply the changes or alternatively restart the Gateway

In this example both NICs em2 (LAN) and em1 (Cameras) are being set to a static IP address

Additional /etc/network/interfaces Examples

In this example NIC em2 (LAN) is set to static and em1 (Cameras) is set to DHCP

In this example NIC em2 (LAN) is set to DHCP and em1 (Cameras) is set to Static

Description

Starting in exacqVision 7.4, the option to enable Dynamic Host Configuration Protocol (DHCP) services is provided. A DHCP server is used to provide IP addresses to any device on the network that requests address assignment.In exacqVision this feature can be used to more easily assign proper IP addresses to cameras. If multiple DHCP servers are listening for requests on the same network and assigning addresses out, at the very least address collisions are possible and most likely devices on the network will start to become segmented and unable to communicate according to which DHCP server they receive an address from.

For these reasons it is strongly recommended to never use more than one DHCP server on a local area network.

If DHCP is enabled on the exacqVision server and inadvertently connected to a network that already has DHCP services running, steps should be taken to remove the exacqVision DHCP server and reconfigure the devices that received an address from exacqVision.

The DHCP server should be disabled or the exacqVision recorder should be disconnected from that network. To disable DHCP navigate to the server’s network configuration tab, uncheck the Enable DHCP server checkbox on each NIC and press Apply.

Reboot any device that received an address from the exacqVision DHCP server. The exacqVision DHCP server will assign addresses in the same network range of exacqVision server NIC it was enabled on. For POE ports on an exacqVision Una server, DHCP is enabled by default and will assign addresses in the 192.168.201-216,2-255 range. After reboot, the device should request and receive a new address from the correct DHCP server.
