13.15.1Description
Configures the authentication parameters of a defined PDP/EPS bearer. The authentication parameters will
be sent during the context activation phase as a protocol configuration options (PCO) information element.
When <auth_type>=3 is set, +CGACT=1,<cid> may trigger at most 3 PDP context activation requests for <cid>
to the protocol stack. The first request for <cid> is done with no authentication. If the PDP context activation
fails, a second attempt is triggered with PAP authentication. If the second PDP context activation fails, a
third attempt is triggered with CHAP authentication. These 3 PDP context activation requests are not to be
confused with the effective number of request PDP context activations sent to the network (see the 3GPP TS
24.008 [12]).
The command returns an error result code if the input <cid> is already active or not yet defined.

Parameter Type Description
<cid> Number See <cid>.
<auth_type> Number Configure the authentication. Allowed values:
• 0: no authentication
• 1: PAP
• 2: CHAP
• 3: automatic selection of authentication type (none/CHAP/PAP)
<username> String Username. The default value is an empty string:
• SARA-R4 / SARA-N4 - The maximum length is 64.
<password> String Password. The default value is an empty string:
• SARA-R4 / SARA-N4 - The maximum length is 64.
13.15.4Notes
• In a PPP dial-up scenario, the authentication parameters set by the +UAUTHREQ command are
overwritten whenever the host provides a new setting via the PPP authentication protocol (PAP or CHAP).
