COMMUNITY NAMESEMM-E6 User’s Guide1-211.8 COMMUNITY NAMESWhen using Local or Remote Management tools to access the EMM-E6 itis important that the Network Manager has the ability to maintain networksecurity. Community Names provide some network security by acting aspasswords into the device and the software running it. The NetworkManager (Super-user) controls access by establishing four (4) passwords.Each of these passwords is associated with a specific level of access to theLocal Management capabilities of the EMM-E6. The Community Namesare set through the Local Management Community Name Table. Oncethese are set by the Network Manager, they can be maintained inconfidence or limited to users who have a need to manage the system. Thefour levels of access are:• Super-User - Allows full management privileges• Read-Write - Allows editing of device configuration parameters notincluding changing Community Names• Read-Only - Allows reading of device parameters not includingCommunity names• Basic-Read - Allows reading low level device data1.9 SNMPSNMP (Simple Network Management Protocol) is a protocol within theTransmission Control Protocol/Internet Protocol (TCP/IP) protocol suite.Network applications such as Local Management and MIB Navigator useSNMP to manage device configurations and monitor operatingconditions. SNMP protocol defines methods for “GETs,” “SETs,” and“TRAPs,” either remotely from any point along the TCP/IP network orlocally. This allows for control of the device from any point along thenetwork. SNMP tools use the MIBs located on the device to be managedto; access information (GET), change device parameters (SET), and tonotify previously selected users that an event has occurred (TRAP).
