I will tell you in context of IOS, similar structure is for NX-OS, but the commands may differ.

For snmp v3 to work properly, you need to configure it in three steps :

1. Create View (to define what is accessible/inaccessible to a user in that view)

2. Create Groups (Member of that view(s))

3. Create user (member of the group(s)).

In your config I see the view is assocated to default view, i would recommend to change it and try to configure a new one.

snmp-server group PXXX2013 v3 auth write v1default

snmp-server group PXXX2013 v3 auth read v1default

Also, the same group name when executed twice, should have only last command executed, so your group command should be like this :

snmp-server group PXXX2013 v3 auth read xxxxx write xxxxxx

v1default is a default view, may be having issues. Confiugure new view this way :

snmp-server view testView iso included

snmp-server view testView xxxx excluded   ----> (optional, in case we want to exclude anything for restricted access)

Rest all seems good. After adding correct credentials in LMS, try to open device in device centre and do a snmpwalk to see if it works.
