Port number the SNMP
agent will
listen to
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.
Allow SNMP set requests You can choose whether or not to allow SNMP set requests on the AP. Enabling
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 .
Read ‐ write community
name (for permitted
SNMP set operations)
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.
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. 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.
IPv6 Hostname or IPv6
subnet of Network
Management System
Specify the IPv6 DNS hostname or subnet of the machines that can execute get and
set requests to the managed devices.
