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.
