The node provides a single PDN connection for each cellular port. A cellular port must have an associated PDN router interface in order to allow routed traffic and services over the PDN connection and over the cellular network. For more information about the PDN router interface, see the 7705 SAR-Hm and SAR-Hmc Main Configuration Guide, 'PDN routerinterfaces'.
The node supports the configuration of an access point name (APN) as part of a PDN profile in order to establish the PDN connection. In many cases, the default PDN profile is sufficient to establish a connection. For example, often the only configuration that is necessary to establish a connection is to enable the port using the config>port port-id no shutdown command. However, some carriers may require the user to configure a specific APN before allowing a connection to be established. In those cases, the user must configure a PDN profile and configure the cellular port to use that PDN profile. See PDN profile for more information.
