Extreme Networks Switch Management
The EPICenter software primarily uses the Simple Network Management Protocol (SNMP) to monitor
and manage the devices in the network. The EPICenter server does an status poll, by default every five
minutes, of all the devices it is managing to determine if the devices are still accessible. It also does a
full detailed poll of each device at longer intervals. This interval for this less frequent detailed polling
can be adjusted on each individual device. The EPICenter software also gives you the ability to gather
device status at any time using the Sync feature in the Inventory Manager applet.
To avoid the overhead of frequent device polling, the EPICenter software also uses a mechanism called
SmartTraps to identify changes in Extreme Networks device configuration. In addition, standard SNMP
MIB-2 traps can be used to define alarms for a large variety of other conditions.

SNMP and MIBs

EPICenter uses SNMP whenever possible to obtain information about the devices it is managing, and to
implement the configuration changes made through EPICenter features.
