Configuration Utility

5Edit the default distributed LAN server configuration:

•(Required) Uncomment (delete the # next to) the line that corresponds to the network interface used by the distributed LAN server when connecting to distributed LAN clients. (For best performance, do not choose the network used for metadata.)

•(Optional) To change a tunable parameter from the default value, uncomment the parameter, and then specify a new value. Table 13 describes the tunable parameters.

Note: The distributed LAN server configuration utility uses the default text editor. If a default text editor has not been specified, the utility uses the vi editor.
