Chapter 5: Enhanced Stacking
94 Section I: Basic Features
Enhanced Stacking Overview
The enhanced stacking feature can make it easier for you to manage the
AT-9400 Series switches in your network. It offers the following benefits:
❑ You can manage up to 24 switches from one local or remote
management session. This eliminates the need of having to
initiate a separate management session with each switch in your
network.
❑ The switches can share the same IP address. This reduces the
number of IP addresses that you need to assign to your network
devices for remote management.
❑ Remotely managing a new switch in your network is simplified.
You connect it to your network. After the switch is connected to
the network, you can manage it immediately from any
management station in your network.

Guidelines
There are a few guidelines to keep in mind when implementing
enhanced stacking for your network:
❑ An enhanced stack cannot span subnets.
❑ All of the switches in an enhanced stack must use the same
management VLAN. For information about Management VLANs,
refer to ”Specifying a Management VLAN” on page 461.
❑ A subnet can contain more than one enhanced stack. You can
create different enhanced stacks within a subnet by assigning the
switches to different Management VLANs.
❑ An enhanced stack must have at least one master switch.
❑ 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-9400 Series switch.
❑ You should assign the master switch an IP address and subnet
mask.
Note
No IP address is required if you intend to manage the enhanced
stack solely through the RJ-45 serial terminal port on a master
switch. However, remote management of a stack using Telnet, a
web browser, or an SNMP application does require assigning an IP
address and subnet mask to a master switch.
❑ You must set a master switch’s stacking status to master.
