The SNMP packet s failing to pass community name authentication are discarded. The community name can limit access to SNMP Agent from SNMP NMS, functioning as a password.
1 19 management station. The specif ied User Name and the Auth/Privacy Password are used for SNMP Management S tation to access the SNMP Agent, functioning as the p assword. SNMP module is used to configure the SNMP f unction of the switch, including three submenus: SNMP Config , Notification and RMON .
120 11.1.2 SNM P View The OID (Object Identifier) of t he SNMP packets is used to describe the managed objects of the switch, and the MIB (Management Information Base) is the set of the OIDs. The SNMP View is created for the SNMP management station to manage MIB objects.
121 Figure 1 1-5 SNMP Group The following ent ries are displaye d on this screen: ¾ Group Config Group Name: Enter the SNMP Group name. The Group Name, Security Model and Security Level compose the identifier of the SNMP Group. The Groups with these three items the same are considered to be the same.
122 Notify V iew : Select the View to be the Notify V iew . The management station can receive trap messages of the assigned SNMP view generate d by the switch's SNMP agent. ¾ Group T able Select: Select the desired entry to del ete the corresponding group.
123 ¾ User Config User Name: Enter the User Name here. User T ype: Select the type for the User . • Local User: Indicates that the user is connected to a local SNMP engine. • Remote User: Indicates that the user is connected to a remote SNMP engine.
124 11.1.5 SNM P Community SNMP v1 and SNMP v2c adopt community name authentication. The comm unity name can limit access to the SNMP agent from SNMP network ma nagement station, functioni ng as a password. If SNMP v1 or SNMP v2c is employed, you can di rectly configure the SNMP Community on this page without configuring SNMP Group and User .
125 Configuration Procedure: z If SNMPv3 is employed, please take the following step s: Ste p Operation Description 1 Enable SNMP function globally . Requir ed. On the SNMP → SNMP C onfig → Global Config page, enable SNMP function globally . 2 Create SNMP View .
126 11.2 Notification With the Notification function enabl ed, the switch can initiatively report to the management station about the important events that o ccur on the V iews (e.g., the manag ed device is rebooted), which allows the management station to monitor and process the events in time.
127 Ty p e : Select the type for the notifications. • Tr a p : Indicates traps are sent. • Inform: Indicates informs are sen t. The Inform type has a higher security than the T rap type. Retry: S pecify the amount of times t he switch resends an inform request.
128 RMON Group Function History Group After a history group is confi gured, the switch collects and records network statistics information periodically , based on which the m anagement station can monitor network effectively . Event Group Event Group is used to define RMON events.
129 11.3.2 Event Config On this page, you can configure the RMON events. Choose the menu SNMP → RMON → Event Config to load the following page. Figure 1 1-10 Event Config The following ent ries are displaye d on this screen: ¾ Event T able Select: Select the desired entry for configuration.

134 Severity Level Description debugging 7 Debug-level messages T able 12-1 Log Level The Log function is implemented on the Log T able , Local Log , Remote Log and Backup Log pages. 12.2.1 Log T able The switch supports logs output to two directions , namely , log buf fer and log file.
135 Severity: Displays the severity level of the log information. Y ou can select a severity level to display the log in formation whose severity le vel value is the same or smaller . Content: Displays the content of the log information. Note: 1. The logs are classified into eight levels based on severity .
136 12.2.3 Remote Log Remote log feature enables the switch to send sy stem logs to the Log Ser ver . Log Server is to centralize the system logs from various devices for the administ rator to monitor and m anage the whole network. Choose the menu Maintenance → Log → Remote Log to load the following page.
