Using server mode on a single master switch and client mode on all other switches will provide the mostfault tolerance for retaining VLAN information in all switches if power is lost on the network.Using transparent mode on all switches will allow for efficient administration and prevent VLAN data lossfrom the loss of any single switch.Configuring several switches in server mode will allow all VLANs to be entered from a single switch andpreserve VLAN data if any of the switches or connections are lost.Configuring one primary and one backup switch in server mode and all other switches in transparent modewill provide fault tolerance for the VLAN data and allow for efficient distribution of the VLANconfigurations to all switches.
