Modeling a Seed Switch
Modeling a Seed Switch
Follow these steps to create a device model to be used as a seed switch.
1. At the Universe level, select File -> Edit to enter the Edit mode.
2. Select Edit -> New Model. The Select Model Type dialog box displays.
3. Select ForeRunner from the Select Model Type dialog box and click OK.
The Creation dialog box displays.
4. Fill in the Creation dialog box parameters as described below.
a. Model Name - Assign a unique name that identifies this switch.
b. Network Address - Enter the Internet Protocol (IP) address that has
been assigned to the switch. The IP address may represent a LAN
address or an ATM network address.
c. Security String - Assign the Security String of the device. Refer to
the Administrator’s Reference for details on setting up security in
SPECTRUM.
d. Polling Interval - Enter the time interval, in seconds, for polling any
attributes that have been flagged as “POLLED.” The default value is
60 seconds.
e. Log Ratio - Enter the number of poll cycles that must be achieved
before the SpectroSERVER writes any attributes that have been
flagged as “LOGGED” to the statistical database. The default value is
10.
5. After filling in the above parameters, click OK. An icon representing the
switch appears at the top of the window.
6. The icon can be moved to another area of the window by dragging it using
the left mouse button while still in the Edit mode.
NOTE
For SPECTRUM to correctly discover and model an ATM network, the
ForeRunner device must have two IP addresses: one for the Ethernet side of
the switch and one for the ATM side. Either IP address can be used for the
purpose of manually modeling the seed switch. See Appendix C, Manual
Modeling, for instructions.
