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, AT-8400 Series, AT-8500 Series, or
AT-9400 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 or DHCP
service on the master switch and have the 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 of the
master switch.
For instructions on how to set the IP address manually, refer to
“Configuring an IP Address and Switch Name” on page 52. For
instructions on activating the BOOTP or DHCP service, refer to
“Activating the BOOTP or DHCP Client Software” on page 55.
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 using Telnet, a web browser, or an
SNMP application does require assigning a master switch an IP
address and subnet mask.
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 83.
