700 Series Managed Switch User’s Guide for Software v2.1
The SNMP Host Table screen allows you to add and remove hosts from access rights that have been granted to community groups. The permissions GET, SET and TRAP are assigned to a community name and then 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.
Host Authorization is a security feature to limit people who are not listed in the host table from accessing the switch using SNMP.

With authentication traps enabled, the system generates a SNMP trap when a host authorization fails. Hosts in community strings with TRAP privileges are notified when a trap occurs.
