SNMP, using polling scheme, is suitable for use in small-sized network environment demanding high
speed and low cost. SNMP, implemented through the connectionless UDP, can seamlessly interoperate
with multiple devices.
SNMP Work Mechanism
The SNMP framework comprises NMS and Agent:
NMS
—Network Management Station NMS, is a station that runs the SNMP client software to monitor and
manage the SNMP-capable devices in the network.
SNMP agent
—Works on a managed network device (such a switch) to receive and handle requests from
the NMS, and send traps to the NMS when some events occur.
Upon receiving GetRequest, GetNextRequest and SetRequest packets from NMS, the SNMP agent will
perform Read or Write operation on managed objects depending on the type of packets received and
generate Response packets to return to NMS.
SNMP Version
The device supports SNMPv3 and is compatible with SNMPv1 and SNMPv2c.
SNMPv3 adopts user name and password authentication mode.
The switch supports SNMPv1 and SNMPv2c, both of which use community names for authentication.
SNMP packets with community names that did not pass the authentication on the device will simply be
discarded. The SNMP community name defines the relationship between an SNMP NMS and an SNMP
Agent. A community name plays a similar role as a key/password and can be used to regulate access
from NMS to Agent.
Trap
Traps are messages that alert network personnel of events that occur on the switch. The events can be
as serious as a reboot (someone accidentally turns off the Switch), or less serious like a port status
change. The switch generates traps and sends them to the trap recipient (or network manager).
