Overview of Configuring and Bringing Up a Stack

This process assumes that:

■All switches you want to include in a stack are connected to the same subnet (broadcast domain).

■If VLANs are enabled on the switches you want to include in the stack, then the ports linking the stacked switches must be on the primary VLAN in each switch (which, in the default configuration, is the default VLAN). If the primary VLAN is tagged, then each switch in the stack must use the same VLAN ID (VID) for the primary VLAN. (See “Which VLAN Is Primary?” on page 9-53, and “Stacking Operation with Multiple VLANs Configured” on page 9-47.)

■If you are including an HP ProCurve Switch 8000M, 4000M, 2424M, 2400M, or 1600M in a stack, you must first update all such devices to software version C.08.xx. (You can get a copy of the software from HP’s ProCurve website and/or copy it from one switch to another. For downloading instructions, see appendix A, "File Transfers", in the Management and Configuration Guide you received with these switch models.)

Options for Configuring a Commander and Candidates. Depending on how Commander and Candidate switches are configured, Candidates can join a stack either automatically or by a Commander manually adding (“pulling”) them into the stack. In the default configuration, a Candidate joins only when manually pulled by a Commander. You can reconfigure a Commander to automatically pull in Candidates that are in the default stacking configura- tion. You can also reconfigure a Candidate switch to either “push” itself into a particular Commander’s stack, convert the Candidate to a Commander (for a stack that does not already have a Commander), or to operate as a standa- lone switch without stacking. The following table shows your control options for adding Members to a stack.
