# == Class: tripleo::profile::base::snmp
#
# SNMP profile for tripleo
#
# === Parameters
#
# [*snmpd_config*]
#   An array of snmp config.
#   Example:
#     snmpd_config:
#       - 'createUser ro_snmp_user MD5 "secrete"',
#       - 'rouser ro_snmp_user'
#       - 'proc neutron-server'
#       - 'proc nova-api'
#   Note: since we give total freedom to configure snmpd_config and don't
#   verify the content, the user will have to ensure that the parameters
#   related to user / password in the array, are the same given to
#   THT via SnmpdReadonlyUserName and SnmpdReadonlyUserPassword.
#   Defaults to undef.
#
# [*snmpd_password*]
#   The SNMP password
#   Defaults to hiera('snmpd_readonly_user_password')
#
# [*snmpd_user*]
#   The SNMP username
#   Defaults to hiera('snmpd_readonly_user_name')
#
# [*step*]
#   (Optional) The current step in deployment. See tripleo-heat-templates
#   for more details.
#   Defaults to hiera('step')
#
