N o t e In the default stack configuration, the Candidate Auto Join parameter is
enabled, but the Commander Auto Grab parameter is disabled. This prevents
Candidates from automatically joining a stack prematurely or joining the
wrong stack (if more than one stack Commander is configured in a subnet or
broadcast domain). If you plan to install more than one stack in a subnet, HP
recommends that you leave
Auto Grab disabled on all Commander switches and
manually add Members to their stacks. Similarly, if you plan to install a stack
in a subnet (broadcast domain) where stacking-capable switches are not
intended for stack membership, you should set the
Stack State parameter (in
the Stack Configuration screen) to Disabled on those particular switches.
Candidate IP Addr: Optional.
Configuring an IP
address allows access
via Telnet or web
browser interface
while the switch is not
a stack member. In the
factory default configu-
ration the switch auto-
matically acquires an
IP address if your
network includes DHCP
service.
Stack Name: N/A n/a Passwords optional. If the
Candidate becomes a stack
Member, it assumes the
Commander’s Manager and
Operator passwords.
If a candidate has a password,
it cannot be automatically
added to a stack. In this case,
if you want the Candidate in a
stack, you must manually add
it to the stack.
Uses standard SNMP
community operation if the
Candidate has its own IP
addressing.
Member IP Addr: Optional.
Configuring an IP
address allows access
via Telnet or web
browser interface
without going through
the Commander switch.
This is useful, for
example, if the stack
Commander fails and
you need to convert a
Member switch to
operate as a replace-
ment Commander.
Stack Name: N/A Up to 15 Members
per stack. When the switch joins the
stack, it automatically
assumes the Commander’s
Manager and Operator pass-
words and discards any pass-
words it may have had while a
Candidate.
Note: If a Member leaves a
stack for any reason, it retains
the passwords assigned to the
stack Commander at the time
of departure from the stack.
Belongs to the same SNMP
communities as the
Commander (which serves
as an SNMP proxy to the
Member for communities to
which the Commander
belongs). To join other
communities that exclude
the Commander, the
Member must have its own
IP address. Loss of stack
membership means loss of
membership in any commu-
nity that is configured only
in the Commander. See
"SNMP Community Opera-
tion in a Stack" on page
13-45.
