If a candidate has a password,
it cannot be automatically

if you want the Candidate in a
stack, you must manually add
it to the stack.

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
