SNMP V1 provides a weak method of authenticating SNMP
requests, using the ‘community name’. This optional parameter allows you
to specify the SNMP V1 community name that will be honoured by SNMPAgent
for read-only access. Defaults to nothing, you have to define one by
yourself.
We strongly recommend that you choose a community name and
keep it secret.
# Use a secret community.
