Figure 6.1: Sample SNMP setup, where one manager station controls two devices
by communicating with SNMP agents running on the managed devices.
❼ Write community: The SNMP write community can be used to write (and
read) SNMP MIB objects to (from) a managed station. Thus, if the agent has
its write community enabled, it is possible to configure the switch via SNMP.
The write community is typically named ”private”.
Default write community: Disabled
❼ Trap community: The SNMP trap community is used when an agent wants
to send a notification to the manager (SNMP Trap). The trap community is
typically named ”public”.
Default trap community: trap
Warning
Using the well-known community strings ”public” and ”private” could pose
a serious security problem.
6.1.3 Trap Support
SNMP traps are only generated if there is at least one Trap Host (i.e., SNMP man-
agement station) defined. Up to three Trap Hosts can be defined. If two or more
Trap Hosts are configured, traps will be sent to all of them.
