ProCurve Stack Management
Operation
IP Addressing and
Stack Name Number Allowed
Per Stack Passwords SNMP Communities
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.
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.
Stack Name: N/A
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
8-44.
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,
ProCurve 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.
