Section I: Basic Features

There are three basic steps to implementing this feature on your
network:

1. Select a switch in your network to function as the master switch of the

stack.

You can select an AT-8400 switch, or any other ATI switch that is
capable of enhanced stacking, to act as the master switch of an
enhanced stack. For networks that consist of more than one
subnet, you must assign at least one master switch in each subnet.

Allied Telesyn recommends that you assign two master switches
to each subnet. That way, if you remove one of the master
switches from the network, such as for maintenance, you are able
to remotely manage the switches in the subnet using the second
master switch.

Note

Only switches connected to the management VLAN of the master
switch can be discovered and managed through enhanced
stacking. Switches that are not connected to the management VLAN
are not discovered even if they are in the same subnet as the master
switch.

2. You must assign the master switch an IP address and a subnet mask.

A master switch must have an IP address and subnet mask. The
other switches in an enhanced stack, referred to as slave switches,
do not need an IP address and a subnet mask.

If your enhanced stack has more than one master switch, you
must assign a unique IP address to each master switch.

You can set an IP address manually or activate the BOOTP and
DHCP services on a master switch and have the master switch
obtain its IP information from a BOOTP or DHCP server on your
network. Initially, assigning an IP address or activating the BOOTP
and DHCP services can only be performed through a local
management session.

Note

For instructions on how to set the IP address manually, refer to
Configuring an IP Address and Switch Name on page 48. For
instructions on activating the BOOTP and DHCP services, refer to
Activating the BootP and DHCP Services on page 57.

3. You must change the enhanced stacking status of the master switch

to Master.
