Configuring SNMP
15
SNMP source enable
Select
Enabled
if you want to restrict the source of permitted SNMP requests to a specified IP
address, hostname, or subnet. When disabled, the HP 501 accepts requests from any device
on the network that is configured with the appropriate community name. It is disabled by
default.
Hostname, address, or subnet
If you have enabled the SNMP source enable setting, specify the hostname or IPv4 address of
a device to enable it to execute get and set requests to the HP 501. Or, specify a subnet to
enable SNMP access for any device on that subnet.
The valid range is 1 to 256 characters.
As with community names, this setting provides a level of security on SNMP accesses. The
SNMP agent accept requests only from the specified device or subnet.
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 also be
specified in this manner. For example, a range of 192.168.1.0/24 specifies a subnet with
address 192.168.1.0 and a subnet mask of 255.255.255.0. In this example, devices with
addresses from 192.168.1.1 through 192.168.1.254 can execute SNMP commands on the HP
501. (The address identified by the suffix .0 is reserved for the subnet address, and the address
identified by .255 is 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. A total
of 126 addresses are designated.
IPv6 hostname, address, or subnet
Specify the DNS hostname, address, or subnet of the IPv6 devices that can execute get and set
requests to the HP 501.
Trap destinations
The HP 501 generates and stores data about significant events, such as system errors and
configuration changes, in the form of SNMP traps. These traps can be forwarded to up to three
SNMP manager devices, which you can configure in the Trap destinations section of the page.
Community name for traps
Enter the global community string associated with SNMP traps. Traps sent from the device
provide this value as a community name.
The valid range is 1 to 256 characters. The community name can be in any alphanumeric
format. Special characters are not permitted.
Enabled
Select the check box to enable configuring up to three devices to receive traps.
Host type
Select whether the devices use an IPv4 or IPv6 address.
Host name or IP address
Specify the hostname or IP address of the selected type.
