3.9 SNMP
SNMP is a standard TCP/IP protocol for network management. Network administrators use SNMP to monitor and
map network availability, performance, and error rates. System management software uses SNMP to allow
administrators to remotely monitor and manage thousands of systems on a network, often by presenting the data
gathered from monitored devices in a snapshot or dashboard view. WoMaster Managed Switch support SNMP v1
and v2c and V3.
SNMP managed network consists of two main components: agents and a manager. An agent is a management
software module that resides in a managed switch. An agent translates the local management information from the
managed device into a SNMP compatible format. The manager is the console through the network.
3.9.1 SNMP V1/V2c SETTING
In this page allows users to define the new community string set and remove the unwanted community string. The
community string can be viewed as the password because SNMP V1/V2c doesn’t request User to enter password
before User tries to access SNMP agent.
The community includes 2 privileges, Read Only and Read and Write.
PRIVILEGE
DESCRIPTION
Read Only
User only has the ability to read the values of MIB tables.
Default community string is Public.
Read and Write
User has the ability to read and set the values of MIB tables.
Default community string is Private.
WoMaster Managed Switch allows users to assign 4 community strings. Type the community string and select the
privilege. Then press
Submit
. When User first installs the device in User network, we highly recommend User to
change the community string. Since most SNMP management application uses Public and Private as their default
community name, this might be the leakage of the network security.
3.9.2 SNMP V3
SNMP v3 can provide more security functions when the user performs remote management through SNMP protocol.
