HP ProCurve Stack Management
IP Addressing and
Stack Name
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
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.

broadcast domain). If you plan to install more than one stack in a subnet, HP

Candidate becomes a stack

If a candidate has a password,
it cannot be automatically

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.

SNMP Communities
Uses standard SNMP
community operation if the
Candidate has its own IP
addressing.
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

tion in a Stack" on page 9-46.
