Host Table
From the SNMP Host Table page, you can 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
addresses to the appropriate community string. Host authorization can be enabled or disabled.
If the host authorization is disabled (the default setting), the switch allows any SNMP manager to access the switch. If the host authorization is enabled, the
administrator can specify up to 16 SNMP managers on the host table that can access the switch.
You must enable host authorization before you can use the host table. Host authorization is a security feature to limit people who are not listed in the host
table from accessing the switch.
Once you have enabled host authorization, you must add the host to this table through the console port connection. Otherwise, the switch cannot access the
end station using SNMP.
