Community Name
Enter a case-sensitive string. The maximum length is 16 characters. The maximum
community is 10.
None
Client Address
Enter the client’s IP address. Any IP address can be accessed if the IP address is
0.0.0.0.
0.0.0.0
Client IP Mask
Enter the client’s IP mask. All addresses allow accesses that are associated with a
single client’s IP address.
For example, the client’s IP address is 192.168.1.X, and its subnet mask is
255.255.255.0. If the client’s IP address is between 192.168.1.0 and 192.168.1.255, it
is allowed to be accessed. If the client’s IP address is 192.168.1.15, and its subnet
mask is 255.255.255.255, only this client allows to be accessed.
0.0.0.0
Access Mode
Specify the access mode:

ReadOnly : Only allow the client to read information.

ReadWrite : Only allow the client to read information and modify configuration.
None
Notice:
The client address and client IP mask denote a range of IP addresses from which the SNMP clients
can access the community on the switch.
3.2.1.2 Trap Configuration
If network engineers need to get information from an SNMP agent (network device), they usually use the SNMP
software to poll information and get a response from an agent. But the SNMP Trap is the unsolicited trap which
sends from the agent to the NMS (Network Management System).The operating theory is shown in the figure
below.
An SNMP agent sends SNMP trap messages to the trap community (trap receiver). It monitors the switch for
particular events or conditions, and generates trap messages based on these events or conditions.
