Table 6.1: WeOS control of SNMP features.
❼ can send SNMP SET messages to the SNMP agent to modify the device set-
tings (or issue commands such as ’reboot’).
❼ can get notified by an agent when specific events occur, such as link down
event, via SNMP TRAP messages.
The objects manageable via SNMP are defined in a management information base
(MIB). The WeOS MIB support aims at providing SNMP management primarily via
standard MIBs to enable easy integration with existing SNMP management tools.
In addition, WeOS includes an enterprise MIB (private MIB) to provide access to
MIB objects not available via the standard MIBs.
6.1.2 SNMP Communities
An SNMP community is a relationship between the manager and managed sta-
tion. It can be seen as a (very) basic authentication and authorisation mechanism
for SNMP v1 and v2c
1 . Three types of communities are supported:
❼ Read community: The SNMP read community is used by a manager to read
SNMP MIB objects from a managed station.
Default read community: public
1 See section 6.1.4 for secure management using SNMPv3.
