COMMUNITY NAMES

1.8COMMUNITY NAMES

When using Local or Remote Management tools to access the EMM-E6 it is important that the Network Manager has the ability to maintain network security. Community Names provide some network security by acting as passwords into the device and the software running it. The Network Manager (Super-user) controls access by establishing four (4) passwords. Each of these passwords is associated with a specific level of access to the Local Management capabilities of the EMM-E6. The Community Names are set through the Local Management Community Name Table. Once these are set by the Network Manager, they can be maintained in confidence or limited to users who have a need to manage the system. The four levels of access are:

•Super-User - Allows full management privileges

•Read-Write - Allows editing of device configuration parameters not including changing Community Names

•Read-Only - Allows reading of device parameters not including Community names

•Basic-Read - Allows reading low level device data

1.9SNMP

SNMP (Simple Network Management Protocol) is a protocol within the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol suite. Network applications such as Local Management and MIB Navigator use SNMP to manage device configurations and monitor operating conditions. SNMP protocol defines methods for “GETs,” “SETs,” and “TRAPs,” either remotely from any point along the TCP/IP network or locally. This allows for control of the device from any point along the network. SNMP tools use the MIBs located on the device to be managed to; access information (GET), change device parameters (SET), and to notify previously selected users that an event has occurred (TRAP).
