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