Chapter 3: Enhanced Stacking
Section I: Basic Operations 46
❑ The enhanced stacking feature uses the IP address 172.16.16.16.
Do not assign this address to any device if you intend to use the
enhanced stacking feature.
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-8500 Series 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 should assign each master switch a unique IP address and a
subnet mask.
A master switch should 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 should assign each
master switch a unique IP address.
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 55. For
instructions on activating the BOOTP and DHCP services, refer to
Activating the BOOTP or DHCP Client Software on page 59.
Note
No IP address is required if you intend to manage an enhanced stack
solely through the RS232 Terminal Port on a master switch.
However, remote management of a stack using Telnet, a web
browser, or an SNMP application does require assigning a master
switch an IP address and subnet mask.
