Configuring Simple Network Management Protocol (SNMP) on the AP

Configuring SNMP Settings

Start/stop control of SNMP agents, community password configuration, access to MIBs, and configuration of SNMP Trap destinations is provided through the U.S. Robotics Professional Access Point as described below.

Field	Description
SNMP Enabled/Disabled	You can choose whether or not you want to enable SNMP on your network. By default SNMP is disabled. To enable SNMP, click Enabled. To disable SNMP, click Disabled. You must click Update to save your settings. Note: If you do not enable SNMP, all remaining fields on the SNMP page will be disabled.
Read-only community name (Entire MIB)	Enter a read-only community name. The community name, as defined in SNMPv2c, acts as a simple authentication mechanism to restrict the machines on the network that can request data to the SNMP agent. The name functions as a passwordm and the request is assumed to be authentic if the sender knows the password. The community name can be in any alphanumeric format.
Allow SNMP SET Requests	You can choose whether or not to allow SNMP SET requests. Enabling SET requests means that machines on the network can execute SET requests to the configured agent on the AP. Note: SET requets are restricted to the Devicescape System MIB. To enable SNMP SET requests, click Enabled. To disable SNMP SET requests, click Disabled.
Designate source of permitted SNMP requests	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.
Source (hostname or subnet)	Specify the 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 AddressRange/MaskLength where AddressRange is an IP address and MaskLength is the number of mask bits. Both formats NetAddress/NetMask and NetAddress/MaskLength are supported. Individual hosts can be priovided 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 indentified 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.

Updating SNMP Settings

To update SNMP settings:

Navigate to the SNMP tab page.
Configure the SNMP settings as required.
