Table 36: SNMP Settings (Cont.)
Description
By default an SNMP agent only listens to requests from port 161. However, you can
configure this so the agent listens to requests on another port.
Enter the port number on which you want the SNMP agents to listen to requests.
The valid range is 1‐65535.
Note: This is a global SNMP parameter that applies to SNMPv1, SNMPv2c, and
SNMPv3.
SNMP set requests means that machines on the network can execute configuration
changes via the SNMP agent on the AP to the D‐Link System MIB. To enable SNMP
set requests, click Enabled. To disable SNMP set requests, click Disabled.
If you have enabled SNMP set requests you can set a read‐write community name.
The valid range is 1‐256 characters.
Setting a community name is similar to setting a password. Only requests from the
machines that identify themselves with this community name will be accepted.
The community name can be in any alphanumeric format.
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. The valid range is 1‐256 characters.
As with community names, this provides a level of security on SNMP settings. The
SNMP agent will only accept 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 would be
designated.
Specify the IPv6 DNS hostname or subnet of the machines that can execute get and
set requests to the managed devices.
