com2sec NAME SOURCE COMMUNITY
              This  directive  specifies  the  mapping  from  a source/community pair to a security name. SOURCE can be a hostname, a subnet, or the word
              "default".  A subnet can be specified as IP/MASK or IP/BITS.  For example, given a directive "com2sec myLocal  10.10.10.0/24  public"  then
              this  would  match  requests  from  IP  addresses  10.10.10.0  through  to 10.10.10.255, but not one from 10.10.11.1 or similar.  The first
              source/community combination that matches the incoming packet is selected.
