A Wireless Wide Area Network (WWAN) card is a specialized network interface card that allows a device to connect, transmit and receive data over a Cellular Wide Area Network. The RFS4000 and RFS6000 each have a PCI Express card slot that supports 3G WWAN cards. The WWAN card uses point to point protocol (PPP) to connect to the Internet Service Provider (ISP) and gain access to the Internet. PPP is the protocol used for establishing Internet links over dial-up modems, DSL connections, and many other types of point-to-point communications. PPP packages your system‘s TCP/IP packets and forwards them to the serial device where they can be put on the network. PPP is a full-duplex protocol that can be used on various physical media, including twisted pair or fiber optic lines or satellite transmission. It uses a variation of High Speed Data Link Control (HDLC) for packet encapsulation.
To switch to the WWAN Interface configuration mode, use the following command:
<DEVICE>(config)#profile <DEVICE-TYPE> <DEVICE-PROFILE-NAME> <DEVICE>(config-profile-<DEVICE-PROFILE-NAME>)#interface wwan1 <DEVICE>(config-profile-<DEVICE-PROFILE-NAME>)#? Interface configuration commands: apn Enter the access point name provided by the service provider auth-type Type of authentication, Eg chap, pap crypto Encryption Module description Port description ip Internet Protocol (IP) no Negate a command or set its defaults password Enter password provided by the service provider shutdown Disable wireless wan feature use Set setting to use username Enter username provided by the service provider clrscr Clears the display screen commit Commit all changes made in this session do Run commands from Exec mode end End current mode and change to EXEC mode exit End current mode and down to previous mode help Description of the interactive help system revert Revert changes service Service Commands show Show running system information write Write running configuration to memory or terminal <DEVICE>(config-profile-<DEVICE-PROFILE-NAME>)#
The following table summarizes WWAN interface configuration commands:
Commands | Description |
---|---|
apn | Configures the access point‘s name provided by the service provider |
auth-type | Configures the authentication types used on this interface |
crypto | Associates a crypto map with this interface |
ip | Associates an IP ACL with this interface |
no | Removes or reverts the WWAN interface settings |
password | Configures a password for this WWAN interface |
use | Associates an IP ACL with this interface |
username | Configures the names of users accessing this interface |
