The Server State Summary Report includes Poller Statistics showing the status of the polling activity
(see
“Server State Summary Report” on page 439 ).
When you select MAC Polling Properties from the drop-down menu field at the top of the properties
panel, you can set the following properties:
Other Properties
When you select Other from the drop-down menu field at the top of the properties panel, you can set
the following properties:
Enable MAC Polling A check in this box enables MAC address polling. Polling is disabled by default.
System Load Tells EPICenter how much impact on EPICenter server performance is acceptable due to
the MAC address polling cycle. EPICenter uses the System Load setting, in conjunction
with the length of time it took for the most recent set of Telnet requests to complete, to
calculate how long to wait before issuing the next set of Telnet requests.
A setting of Light (recommended) means EPICenter will calculate a relatively longer
interval before the next set of Telnet requests, to place a lighter load on the EPICenter
server. This in turn means it will take longer for the server to accomplish a complete
MAC Address polling cycle.
Moving the load indicator towards Heavy will result in shorter elapsed times between
sets of Telnet requests, at the cost of a heavier load on the EPICenter server due to
MAC address polling. However, if your polling data is frequently out of date, moving this
setting towards Heavy may result in more timely data.
DNS Lookup Timeout
Period The time-out period, in seconds, when performing DNS lookup operations for hosts
found through DLCS or when importing (in the Grouping applet) from an NT Domain
Controller. The default is one second.
Session Timeout Period The non-activity time-out period, in minutes, after which the user is required to re-login
to the EPICenter server. The default is 30 minutes. You can disable the time-out by
setting the property to -1.
ServiceWatch URL The URL for accessing ServiceWatch, to allow it to be launched from the EPICenter
Navigation Toolbar, and to run in the main EPICenter applet window.
For example, if ServiceWatch is running on a system named “tampico” at port 2000,
you would enter
http://tampico:2000
as the ServiceWatch URL. You must then
restart the EPICenter server to activate the ServiceWatch integration.
IP QoS Rule Precedence The starting value that the EPICenter server will use for setting precedence in the Policy
Manager applet. This is an integer between 1 and 25,000. The default value is 10,000.
Setting this value lets you ensure that policies created by EPICenter will have higher
precedence than policies created through the ExtremeWare CLI. It is also useful in
distinguishing between policies created through the CLI and those created through the
EPICenter Policy Manager applet.
Client Port The TCP port number that a client will use to connect to the EPICenter server. The
default is 0, meaning that the server will use any available port. You can use this
setting to specify a fixed port number that the EPICenter server will use. For example, if
the EPICenter server is behind a firewall, you may need to provide a fixed port number
to allow clients to connect thought the firewall.
Update Type Library on
Server This function updates the EPICenter type library, which is a repository of information
about devices (primarily from Extreme Networks) that are supported by EPICenter.
Device Tree UI A setting that specifies how devices are identified in the Component Tree and in
selected other locations. You can choose to have the component tree show the device
name only, the device name followed by the IP address in parentheses, or the device IP
address followed by the device name in parentheses. The default is device name
followed by the device IP address.
