Parameters and Values
<cid> Context identifier.
1 Numeric parameter that specifies a particular PDP context definition.
<primary> String type, manual primary DNS server, in the format “xxx.xxx.xxx.xxx” used for
the specified cid. Use this value instead of the primary DNS server from the
network. Default: “0.0.0.0”.
<secondary> String type, manual secondary DNS server, in the format “xxx.xxx.xxx.xxx” used
for the specified cid. Use this value instead of the secondary DNS server from the
network. Default: “0.0.0.0”.
Notes
 If <primary> is ”0.0.0.0” and <secondary> is not “0.0.0.0”, then issuing AT#DNS=… raises an error.
 If <primary> is ”0.0.0.0” you are using the primary DNS server from the network as consequence of a context
activation.
 If <primary> is not ”0.0.0.0” and <secondary> is “0.0.0.0”, then only the manual primary DNS server is used.
 If the context identified by <cid> has not been activated, issuing AT#DNS= causes an error.
