Restrict the source of 
SNMP requests to 
only the designated 
hosts or subnets
You can restrict the source of permitted SNMP requests.
To restrict the source of permitted SNMP requests, click 
Enabled
.
To permit any source submitting an SNMP request, click 
Disabled.
Hostname, address or 
subnet of Network 
Management System
Specify the IPv4 DNS hostname or subnet of the 
machines that can execute get and set requests to the 
managed devices.
As with community names, this provides a level of 
security on SNMP settings. The SNMP agent only accepts 
requests from the hostname or subnet specified here.
To specify a subnet, enter one or more subnetwork 
address ranges in the form 
address/mask_length 
where 
address is an IP address and mask_length is the 
number of mask bits. Both formats 
address/mask and 
address/mask_length are supported. Individual hosts 
can be provided for this, i.e. I.P Address or Hostname. For 
example, if you enter a range of 
192.168.1.0/24 this 
specifies a subnetwork with address 
192.168.1.0 and 
a subnet mask of 
255.255.255.0. 
The address range is used to specify the subnet of the 
designated NMS. Only machines with IP addresses in this 
range are permitted to execute get and set requests on 
the managed device. Given the example above, the 
machines with addresses from 
192.168.1.1 through 
192.168.1.254 can execute SNMP commands on the 
device. (The address identified by suffix .0 in a 
subnetwork range is always reserved for the subnet 
address, and the address identified by 
.255 in the range 
is always reserved for the broadcast address). 
As another example, if you enter a range of 
10.10.1.128/25, machines with IP addresses from 
10.10.1.129 through 10.10.1.254 can execute 
SNMP requests on managed devices. In this example, 
10.10.1.128 is the network address and 10.10.1.255 
is the broadcast address. 126 addresses are designated.
