Chapter 4: Enhanced Stacking
80 Section I: Basic Operations
Enhanced Stacking Overview
The enhanced stacking feature can make it easier for you to manage the
AT-8500 Series switches in your network. It offers the following benefits:
ˆ 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.
ˆ The switches can share the same IP address. This reduces the
number of IP addresses you have to assign to your network devices
for remote management.
ˆ Remotely managing a new switch in your network is simplified. You
simply connect it to your network. Once connected to the network, you
can begin to manage it immediately from any workstation in your
network.
Guidelines
There are a few guidelines to keep in mind when implementing enhanced
stacking for your network:
ˆ An enhanced stack cannot span subnets.
ˆ 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 579.
ˆ You can create multiple enhanced stacks within a subnet by assigning
the switches to different Management VLANs.
ˆ An enhanced stack must have at least one master switch.
ˆ The master switch can be any switch that supports enhanced stacking,
such as an AT-8000 Series, AT-8400 Series, AT-8500 Series, or
AT-9400 Series switch.
ˆ You should assign the master switch an IP address and subnet mask.
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.
ˆ You must set a master switch’s stacking status to Master. For
instructions, refer to “Setting a Switch’s Enhanced Stacking Status” on
page 83.
ˆ 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.
