Section 5 - Configuring Access Point Services
Field
Description
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. IP 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.
Community name
for traps
Enter the global community string associated with SNMP traps. The valid range is 1-256
characters.
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. The valid
range is 1-256 characters.
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.
Table 37 -
SNMP Settings
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.
Setting the SSH Status
Secure Shell (SSH) is a program that provides access to the DWL-x600AP CLI from a remote host. SSH is more
secure than Telnet for remote access because it provides strong authentication and secure communications over
insecure channels. From the SSH page, you can enable or disable SSH access to the system.
