Since read-only is the default, it does not need to be defined explicitly.

community-string — a security string that identifies a community of managers who are permitted
to access the SNMP server
acl-number — ID number if the Access Control List to be assigned to the SNMP interface. It should
list the IP addresses of the SNMP managers permitted to use the community string to gain access to
the agent.
If no ACL is specified, all IP addresses can access the agent using the defined community string.
For more information about ACLs, see
ro — read only (default accessibility)
rw — read and write
