Source Address Functions

Using the Find Source Address window; locking and unlocking ports; viewing the source address table; setting the Device Ageing Time

Each Cabletron repeater device maintains a Source Address List, or Table (SAT), for each port. This table contains the MAC address for each device that is communicating through that port on the IRM2-controlled hub. Your Enterasys management application has three windows that allow you to use the IRM2 Source Addressing feature:

Find Source Address allows you to detect the specific IRM2 port through which a given MAC address is communicating.

Port Locking/Unlocking lets you secure your IRM2 against unknown source addresses trying to access a port.

Source Addressing displays the source address table, which allows you to see the MAC address of each device communicating through a port.

Find Source Address

Find Source Address allows you to discover the port through which a specific Ethernet address is communicating.

To open the Find Source Address window:

1.Click on Repeater on the Chassis View menu bar.

2.Drag down to Find Source Address... and release. The Find Source Address window, Figure 4-1, will appear.
