SNMP
General
Cisco WAP131 and WAP351 Administration Guide
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—Enter 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 the 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. Choose 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—Enter the IPv4 IP address, DNS host name, or
subnet of the network management system (NMS), or the set of machines
that can execute get and set the requests to the managed devices.
A DNS host name can consist of one or more labels, which are sets of up to
63 alphanumeric characters. If a host name 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 the
SNMP settings. The SNMP agent only accepts the requests from the IP
address, host name, 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
