Viewing Device Information
To use the Device Find Source Address window: 
1.
In the Address Mode field, select the format of the Source Address you wish 
to find, either MAC or Canonical
2.
In the Enter Address text box, enter the Source Address you wish to find in 
the appropriate XX-XX-XX-XX-XX-XX format. 
3.
Click on the Find It! button. A “Processing Request” message will appear in 
the status bar at the bottom of the window. 
If the specified MAC address is located, a list of the interface(s) through which the given 
address is communicating will appear in the list box. A status message at the bottom of the 
window will display
 
the number of interfaces through which the given MAC address is 
communicating.
If the specified MAC address cannot be found, a “Source Address not found” message 
will appear.
Using Device Find Source Address on Ethernet MicroLAN Modules
When you select the Device Find Source Address option on an Ethernet MicroLAN 
module (e.g., the 6E123-50 or 6E133-49), a search is made of both the Source Address 
Table (SAT) and the 802.1d Filtering database to discover through which interface(s) a 
specified source MAC address is communicating. If the MAC address is found, the 
interface types “Bridge” and “Enet #” will display in the Component field with their 
associated port index number displayed in the Port Instance field. 
To open the Device Find Source Address window:
NOTE
If you enter the MAC format of a specified address, and then click on Canonical, NetSight 
Element Manager will do the address conversion for you. The same is also true if you 
enter the Canonical format of a specified address and then select MAC.
NOTE
If the MAC address is entered in an incorrect format, an “Invalid MAC Address. 
Enter Valid MAC Address
” message will appear. Enter the address in the correct
XX-XX-XX-XX-XX-XX hexadecimal format.
NOTE
You may receive an error message stating “Can’t Display Source Address” if a Port 
Instance of “0” or “0.0” is reported while using the Device Find Source Address feature. 
This value indicates that the MAC address is communicating through the backplane 
instead of through a front panel interface.
