Network Management
Use the Network menu to make network configuration settings as well as service support settings.
WAN Configuration
From the Network menu, choose WAN, and the WAN Configuration screen appears. This screen displays the network parameters of the WAN connection. You may change any of these items and press Apply to confirm your settings. See a description of each item in the following table:
WAN Configuration
Item | Description |
Host name | Host name that identifies the M3800 on the network. |
Domain name | Specifies the domain name of the M3800. |
MAC Address | MAC address of the network interface. |
Jumbo Frame Support | Enable or disable Jumbo Frame Support of the WAN interface on |
| your M3800. |
WAN Port | Enable or disable the M3800 from obtaining in IP address via |
| DHCP server. If you require a static IP, disable this feature and |
| input your network configuration. |
IP | IP address of the WAN interface. |
Netmask | Network mask, which is generally: 255.255.255.0 |
Gateway | Default Gateway IP address. |
DNS Server | Domain Name Service (DNS) server IP address. |
IP Sharing Mode | When enabled, PCs connected to the LAN port will be able to |
| access the WAN. Default is Enabled. |
NOTE
WARNING
•Only use Jumbo Frame settings when operating in a Gigabit environment where all other clients have Jumbo Frame Setting enabled.
•Enabling DHCP automatically turns on
•If you are only using the WAN port, we suggest that you disable IP Sharing Mode. This will result in higher throughput.
•A correct DNS setting is vital to networks services, such as SMTP and NTP.
Most Fast Ethernet (10/100) Switches/Routers do not support Jumbo Frame and you will not be able to connect to your M3800 after Jumbo Frame is turned on. If this happens, turn off the M3800. Then, power on the M3800 and immediately press and hold the Reset button on the back of the unit for 5 seconds. This will reset your network settings, password, and turn off Jumbo Frame Support.
