Setting Up SNMP
SNMP (Simple Network Management Protocol) is a transport protocol used for network
management. The protocol is used in communication between a Manager—the management
station—and an agent within the managed device, in this case your switch. The Manager polls the
agent which responds by returning data from the Management Information Bases (MIBs) that it
maintains on the managed device to indicate its status. An agent can return Traps to the Manager,
Traps are messages that alert the manager to conditions that may need attention. Managers and
Agents work within Communities which are defined to confine messaging within named groups.
An agent only responds to requests from Managers within its community.
The SNMP screen allows you to limit the IP addresses from which the switch MIBs can be
accessed and to which IPs the switch sends SNMP traps. The switch only responds to requests
from management computers whose IP addresses are carried in the list. This list also holds
Privilege information that controls which IPs have read-only or read-write access. You can also
select the traps which the switch sends to the hosts from the following trap events. The Status field
must be set to Enable to allow management host communication.
Trap Events are indicated by:
•
T1: Authentication fail – The switch generates an SNMP trap when a host tries to gain access
to the switch but the host's IP is not in the SNMP host table.
•
T2: Device bootup – The switch generates an SNMP trap when it reboots.
