The acl group contains one or more lists of community configurations.
acl = { list1 list2 ... listN }
Each list has the following format:
{ communities = communityList access = accessRights managers = hostList }
The communityList is a list of SNMP community names to which this access control applies. The community names in this list are separated by commas.
The accessRights specifies the rights to be granted to all managers running on the machines specified in the managers item. There are two possible values: either read-write or read-only.
The hostList item specifies the host machines of the managers to be granted the access rights. The hostList is a comma-separated list of hosts, each of which can be expressed as any one of the following:
A host name
An IP address
A subnet mask
To distinguish between IP addresses and subnet masks in an ACL file, each integer in a subnet mask is separated by an exclamation mark (!) instead of a dot.
