proper operation, monitor performance and detect potential problems in the Switch, switch group or network.
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 operations on managed objects depending on the type of packets received and generate Response
packets to return to NMS
SNMP Version
The device supports SNMP v3 and is compatible with SNMP v1 and SNMP v2c.
SNMP v3 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 turned 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).
