The community name acts as a simple authentication feature to restrict the machines on
the network that can request data to the SNMP agent. The name functions as a password,
and the request is assumed to be authentic if the sender knows the password.
•
Read-write Community—A read-write community name to be used for SNMP set
requests. The valid range is from 1 to 256 alphanumeric and special characters.
Setting a community name is similar to setting a password. Only requests from the
machines that identify themselves with this community name are accepted.
•
Management Station—Determines which stations can access the WAP device through
SNMP. Select one of these options:
-
All—The set of stations that can access the WAP device through SNMP is not
restricted.
-
User Defined—The set of permitted SNMP requests is restricted to those specified.
•
NMS IPv4 Address/Name—The IPv4 IP address, DNS hostname, or subnet of the
network management system (NMS), or the set of machines that can execute get and set
requests to the managed devices.
A DNS hostname can consist of one or more labels, which are sets of up to 63
alphanumeric characters. If a hostname includes multiple labels, each is separated by a
period (.). The entire series of labels and periods can be up to 253 characters long.
As with community names, this setting provides a level of security on SNMP settings.
The SNMP agent only accepts requests from the IP address, 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. 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.)
