MAC Address Tables
The MAC address tables of the switches in a stack are all the same. This
is because the switches share their MAC addresses as they learn them.
When a switch learns a new address on a port, it stores the address in its
MAC address table and sends the address from the AT-StackXG Stacking
Module to the other switches, which store the address in their tables.
When you view the MAC address table of a stack with the web browser
windows, you can only view the table on the master switch. But since the
tables in a stack are all the same, the master switch has the same table as
all the other switches.
Viewing the MAC address table of a stack from the command line is a little
different because you can select to view the table of a particular member
switch, rather than the master switch. Why would this be useful if the
tables in a stack are all the same? Delays can occur between when
member switches learn new addresses and share them with the other
units. This option lets you view addresses that member switches may have
learned but haven’t had a chance to share yet.
File Systems
The file system on the master switch is the only accessible file system in a
stack. The file systems on the member switches are not accessible.
Compact Flash Memory Card Slots
The master switch of a stack has the only active compact flash memory
slot. The slots in the member switches are inactive.
