switch using SNMP. EPICenter also adds itself on the switch as a trap receiver. The
switch uses the SmartTraps rules to determine what traps to send to EPICenter.
When EPICenter receives a trap from a switch, it then polls the switch for detailed
status information.
• EPICenter polls every network device periodically (approximately every five minutes
by default) to update basic switch status, which is a subset of the status and
configuration information kept in the database. This poll interval is set globally for all
devices being managed by the EPICenter server, and can be changed through the
Server Properties settings in the Administration applet. See “Server Properties
Administration” in Chapter 15.
• The EPICenter server polls each device periodically for detailed status information.
This is donemuch less frequently than the basic status polling—by default, once every
30minutesfor core (chassis) devices,and once every 90 minutes for edge devices. This
poll interval can beset individually for devices through the Modify Device interface in
the Inventory applet (see the discussion “Modifying a Device” on page 4-18).
• A user with Administrator or Manager access can use the Sync command from the
Inventory Manager. Sync is a manual update of the regular data gathering
mechanisms, for use when the users believes that the device configuration or status is
not correctly reported in EPICenter applets. Sync causes EPICenter to poll the switch
and update all configuration and status information. During a Sync operation the
SmartTraps rules arealso reset in casetheuser has accidentally deleted thetrapreceiver
or any SmartTrap rules.
