The new unit you are putting into the stack should have everything configured to match the one coming out, including the unit number it will be in the stack, before it is inserted into the stack. The stack will reset when the new unit is added which is probably what you experienced in the past.

I need to replace a Nortel Business Policy 2000 switch that is in a stacked configuration. There are no vlans on these switches. The last time we replaced a switch in the stack many hosts could not connect for a brief period of time. Afterwards all hosts were able to connect. Whas this just the arp table refreshing itself? &nbsp;What was the cause of this and will it happen again? Is there any way around this?<br />

Thanks

Replacing Nortel switch that is in a stacked configuration

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
