There are three basic steps to implementing this feature on your
network:
1. You must select a switch in your network to function as the master
switch of the 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 other
switches in the stack using the second master switch.
2. You must assign the master switch an IP address and subnet mask.
A master switch must have an IP address and subnet mask. The
other switches in an enhanced stack, referred to as slave switches,
do not.
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 client software on a 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 41. For
instructions on activating the BOOTP and DHCP services, refer to
Activating the BOOTP and DHCP Client Software on page 44.
3. Change the enhanced stacking status of the master switch to Master.
This is explained in the procedure Setting a Switch’s Enhanced
Stacking Status on page 61.
