Table 25 SNMP Settings (Continued)
Field
Restrict the source of
SNMP requests to
only the designated
hosts or subnets
Hostname, address or
subnet of Network
Management System
Description
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.
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.
