There are three basic tasks to implementing this feature on your network:
ˆ You must select a switch in each subnet of your network to function as
the master switch of the enhanced stack for that subnet.
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.
Allied Telesyn recommends 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.
ˆ 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 must
assign each master switch a unique IP address.
Note
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 or DHCP service
can only be performed through a local management session.
For instructions on how to set the IP address manually, refer to
“Configuring the IP Address, Switch Name, and Other Basic
Parameters” on page 54. For instructions on activating the BOOTP
or DHCP service, refer to “Activating the BOOTP or DHCP Client
Software” on page 57.
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.
ˆ Change the enhanced stacking status of the master switch to master.
This is explained in “Setting a Switch’s Enhanced Stacking Status” on
page 87.
