4.2.6 System Admin->SNMP Configuration->Authorized Managers
Use the SNMP Host Table to add and remove hosts from access rights granted to community groups. The permissions GET, SET, and TRAP are assigned to a community name. These permissions are assigned to individual machines by adding those machines and their IP address to the appropriate community string. Host Authorization can be Enabled or Disabled. Use Host Authorization as a security feature to limit people who are not listed in the host table from accessing the switch using SNMP.
