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.)
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 would be
designated.
• NMS IPv6 Address/Name—The IPv6 address, DNS hostname, or subnet of
the machines that can execute, get, and set requests to the managed
devices. The IPv6 address should be in a form similar to
xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx (2001:DB8::CAD5:7D91).
A 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.
STEP 5 Configure the SNMPv2 trap settings:
• Trap Community—A global community string associated with SNMP traps.
Traps sent from the device provide this string as a community name. The
valid range is from 1 to 60 alphanumeric and special characters.
