Configuring SNMP & RMON Notification Configurations 3.1.2 Enabling SNMP Traps Choose the menu MAINTENANCE > SNMP > Notification > Trap Config to load the following page. Figure 3-2 Enabling SNMP Traps Follow these steps to enable some or all of the supported traps: 1) Select the traps to be enabled according to your needs. With a trap enabled, the switch will send the corresponding trap message to the NMS when the trap is triggered. SNMP Authentication Triggered when a received SNMP request fails the authentication. Coldstart Indicates that the SNMP entity is reinitializing itself such that its configurations may be changed. The trap can be triggered when you reboot the switch. Warmstart Indicates that the SNMP entity is reinitializing itself with its configurations unchanged. For a switch running SNMP, the trap can be triggered if you disable and then enable SNMP without changing any parameters. Link Status Enable or disable Link Status Trap globally. The trap includes the following two sub-traps: Linkup Trap: Indicates that a port status changes from linkdown to linkup. Linkdown Trap: Indicates that a port status changes from linkup to linkdown. Link Status Trap can be triggered when it is enabled both globally and on the port, and you connect a new device to the port or disconnect a device from the port. To enable the trap on a port, run the command snmp-server traps linkstatus in Interface Configuration Mode of the port. To disable it, run the corresponding no command. By default, the trap is enabled both globally and on all ports, which means that link status changes on any ports will trigger the trap. If you do not want to receive notification messages about some specific ports, disable the trap on those ports. User Guide 871
