NETGEAR M7100, M4100 manual Preconfigure a Switch, Switch Stack Master Scenarios

ProSafe M4100 and M7100 Managed Switches

The following table provides switch stack configuration scenarios. Most of the scenarios assume at least two switches are connected through their stacking ports.

Preconfigure a Switch

You can preconfigure (supply a configuration to) a new switch before it joins the switch stack. You can specify the stack member number, the switch type, and the interfaces associated with a switch that is not currently part of the stack.

Note: If you are replacing a switch with the same model in the same position in the stack, you do not need to preconfigure it. The new switch assumes the same configuration as the previous switch.
