Chapter 3: Enhanced Stacking
Section I: Basic Operations 50
There are three basic steps to implementing this feature on your
network:
1. You must select a switch to function as the master switch of the
enhanced stack.
The master switch can be any switch that supports enhanced
stacking, such as an AT-8000 Series switch, an AT-8400 Series
switch, or an AT-8524M switch. For networks that consist of more
than one subnet, there must be at least one master switch in each
subnet.
It is recommended that each enhanced stack have two master
switches, each assigned a unique IP address. That way, should you
remove one of the master switches from the network, such as for
maintenance, you all still be able to remotely manage the
switches in the stack using the other master switch.
2. You must assign each master switch a unique IP address and a subnet
mask.
A master switch must have a unique IP address and a subnet
mask. The other switches in an enhanced stack, referred to as
slave switches, do not need an IP address.
If an enhanced stack will have more than one master switch, you
must assign each master switch a unique IP address.
Note
You can set the 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.
For instructions on how to set the IP address manually, refer to
Configuring an IP Address and Switch Name on page 59. For
instructions on activating the BOOTP and DHCP services, refer to
Activating the BOOTP and DHCP Client Software on page 62.
3. Change the enhanced stacking status of the master switch to Master.
This is explained in Setting a Switch’s Enhanced Stacking Status
on page 52.
