HP ProCurve Stack Management

■Stacking uses only the primary VLAN on each switch in a stack.

■The primary VLAN can be tagged or untagged as needed in the stacking path from switch to switch.

■The same VLAN ID (VID) must be assigned to the primary VLAN in each stacked switch.

Web: Viewing and Configuring Stacking

Figure 9-38. Example of the Web Browser Interface for a Commander

The web browser interface for a Commander appears as shown above. The interface for Members and Candidates appears the same as for a non-stacking Series 2500 switch.

To view or configure stacking on the web browser interface:

1.Click on the Configuration tab.

2.Click on [Stacking] to display the stackingconfiguration for an individual switch, and make any configuration changes you want for that switch.
