The node uses PDN profiles to establish PDN connections over a cellular port. When the default PDN profile is not sufficient to establish connections, a PDN profile must be created. Manually created PDN profiles contain additional cellular network access configuration items that are not stored on the SIM but that are required in order to establish a PDN connection. PDN profiles can be created, modified, and deleted.
A PDN profile is referenced using a PDN profile ID. When a PDN profile is created at the system level and then configured on a cellular port, it cannot be modified or deleted until it is removed from the cellular port.
PDN profiles are necessary so that CLI or SNMP changes can be made to cellular ports without first having to shut down the ports. For example, when changing the APN information for a cellular port, another PDN profile can be configured with the changed information and assigned to the cellular port. This change will cause the cellular port to connect to the cellular network using the new PDN profile information immediately.
The following items can be configured as part of a PDN profile:
APN—the Access Point Name provided by the service provider to use for the cellular service
authentication—the type of authentication to use for establishing the connection, either Password Authentication Protocol (PAP) or Challenge Handshake Authentication Protocol (CHAP)
description—a description for the PDN profile
password—a password for the PAP or CHAP authentication
protocol—the protocol for the associated PDN interface, either IPv4 or IPv6
username—a username for the PAP or CHAP authentication
The following CLI syntax shows an example of how to configure a PDN profile.
*A:Dut# config>system>cellular# pdn-profile 1
*A:Dut>config>system>cellular>pdn-prof# apn apn1
*A:Dut>config>system>cellular>pdn-prof# authentication pap
*A:Dut>config>system>cellular>pdn-prof# description "PDNprofile1"
*A:Dut>config>system>cellular>pdn-prof# no password
*A:Dut>config>system>cellular>pdn-prof# protocol ipv6
*A:Dut>config>system>cellular>pdn-prof# username waldowaldo
*A:Dut>config>system>cellular>pdn-prof# exit
*A:Dut>config>system>cellular# exit
*A:Du>config>system# exit
*A:Dut>config# exit
*A:Dut#
