ePMP: Configuring SM units using the Quick Start menu

The Quick Start tab contains a simple listing of parameters required to configure a simple radio link and to configure requisite networking parameters.

To configure a SM via the Quick Start menu, follow this procedure:

Step

Action

1

Start the web browser from the management PC.

2

Navigate to Quick Start menu

3

Configure the parameter Radio Mode:

This parameter controls the function of the device – all ePMP devices may be configured to operate as an Access Point (AP), Subscriber Module (SM), or as a Spectrum Analyzer. For initial link bring-up, choose Subscriber Module.

4

Configure the parameter Subscriber Module Mode:

This parameter controls the mode of operation of the Subscriber Module – An SM may be configured to operate in TDD mode for point-to-point and point-to-multipoint access, Standard WiFi mode providing the capability to connect to any AP operating in standard WiFi mode or as an ePTP Slave. For initial link bring-up, choose TDD. When the SM is an ePTP Slave, the system does not support GPS Synchronization but is able to provide significantly lower latency than other modes. QoS (MIR and traffic priority) capability and Link Quality/Capacity indicators are not available in this mode.

5

The Country is automatically retrieved from the AP and requires no configuration.

Country settings affect the radios in the following ways:

•        Maximum transmit power limiting (based on radio transmitter power plus configured antenna gain)

•        DFS operation is enabled based on the configured country code, if applicable

•        Frequency range of operation depending on local limitations

6

Configure the parameter Device Name:

The SM Device Name is used to identify the device on the network. This parameter may be modified or left at the default value of Cambium-SM.

7

Configure the parameter Network Mode:

Bridge: The SM acts as a switch, and packets are forwarded or filtered based on their MAC destination address.

NAT: The SM acts as a router, and packets are forwarded or filtered based on their IP header (source or destination) which can be grouped into subnets for finer granularity.

Router: The SM acts as a router and packets are forwarded or filtered based on their IP header (source or destination) using specific static routes and IP aliases configured by the operator.

8

Configure the parameter Wireless IP Assignment:

If DHCP is selected, the DHCP server automatically assigns the IP configuration (Ethernet (LAN) IP Address, Ethernet (LAN) IP Subnet Mask, Gateway IP Address (LAN)) and the values of those individual parameters (below) are not used.  To configure a simple test network, this parameter must be configured to Static.

9

Configure the parameter Wireless IP Address:

Internet Protocol (IP) address. This address is used by the family of Internet protocols to uniquely identify this unit on a network. To configure a simple test network, this field must be configured to 192.168.0.2.

10

Configure the parameter Wireless Subnet Mask:

The Subnet Mask defines the address range of the connected IP network. To configure a simple test network, this field may be left at default (255.255.255.0).

11

Configure the parameter Wireless Gateway:

The IP address of the device on the current network that acts as a gateway. A gateway acts as an entrance and exit to packets from and to other networks. To configure a simple test network, this parameter may be left at default (blank).

12

Configure the parameter IPv6 Assignment

IPv6 Assignment specifies how the IPv6 address is obtained.

Static:  Device management IP addressing is configured manually in fields IPv6 Address and IPv6 Gateway. 

DHCPv6:  Device management IP addressing (IP address and gateway) is assigned via a network DHCP server, and parameters IPv6 Address and IPv6 Gateway are unused. If the DHCPv6 server is not available previous static IPv6 address will be used as a fallback IPv6 address. If no previous static IPv6 address is available, no IPv6 address will be assigned. DHCPv6 will occur over the wireless interface by default.

13

Configure the parameter IPv6 Address

Internet protocol version 6 (IPv6) address. This address is used by the family of Internet protocols to uniquely identify this unit on a network.

IPv6 addresses are represented by eight groups of four hexadecimal digits separated by colons.

14

Configure the parameter IPv6 Gateway

Configure the IPv6 address of the device on the current network that acts as a gateway. A gateway acts as an entrance and exit to packets from and to other networks.

15

Configure the parameter WPA2 Pre-shared Key:

Configure each of the network SMs with this key (matching the AP’s configured key) to complete the authentication configuration. This key must be between 8 to 128 symbols. Click the visibility icon visibility icon.png   to toggle the display of the key’s contents.

16

Configure the parameter EAP-TTLS Username:

Configure each of the network SMs with this EAP-TTLS Username (matching the credentials on the RADIUS server being used for the network).  Optionally, the device MAC Address can be used as the EAP-TTLS Username in either “:” or “-“ delimited format.

17

Configure the parameter EAP-TTLS Password:

Configure each of the network SMs with this EAP-TTLS Password (matching the credentials on the RADIUS server being used for the network). Click the visibility icon  to toggle the display of the password’s contents.

18

Configure the parameter Authentication Identity String:

Configure each of the network SMs with this Identity string (matching the credentials on the RADIUS server being used for the network).  Default value for this parameter is “anonymous”.

19

Configure the parameter Authentication Identity Realm:

Configure each of the network SMs with this Identity realm (matching the credentials on the RADIUS server being used for the network). Default value for this parameter is “cambiumnetworks.com”.

20

Configure the Preferred AP’s

The Preferred AP’s is comprised of a list of up to 16 APs to which the SM sequentially attempts registration. For each AP configured, if authentication is required, enter a Pre-shared Key associated with the configured AP SSID.  If this list is empty or if none of the configured APs are found, the SM scans and registers to the best AP signal found (with matching radio and/or authentication settings).

21

Configure the parameter Subscriber Module Scanning:

The Radio Scan List determines the frequencies for which the SM scans for AP signaling. For a simple radio network setup, click Select All to scan all frequencies.
