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.
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 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 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, address, or
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.
Community name for traps Enter the global community string associated with SNMP traps.
Traps sent from the device will provide this string as a community name.
The community name can be in any alphanumeric format. Special characters are not
permitted.
Hostname or IP address Enter the DNS hostname of the computer to which you want to send SNMP traps. An example
of a DNS hostname is:
snmptraps.foo.com.
Since SNMP traps are sent randomly from the
SNMP agent, it makes sense to specify where exactly the traps should be sent. You can add
up to a maximum of three DNS hostnames. Ensure you select the Enabled check box beside
the appropriate hostname.
Note: After you configure the SNMP settings, you must click Apply to apply the changes and to save the settings.
Changing some settings might cause the AP to stop and restart system processes. If this happens, wireless clients
will temporarily lose connectivity. We recommend that you change AP settings when WLAN traffic is low.
