Reducing Memory Usage, Local Show Node Peach Status

Managing Your Access Server As Part of the LAT Network

The following example shows how to decrease the node limit to 100:

Local> CHANGE SERVER NODE LIMIT 100

Reducing Memory Usage

Set the node limit characteristic to a lower value. The access server automatically reduces the number of nodes in the database. This reduces the amount of memory used by the node database.

Viewing LAT Node Status Information

The SHOW/MONITOR NODE STATUS command displays information about the status of the selected nodes. This includes a list of the services offered by the nodes and information on each service. This display can help you track the availability and use of services.

Example: SHOW NODE STATUS Display

The following example shows how to generate a status display for the service node called PEACH:

Local> SHOW NODE PEACH STATUS
Node:	PEACH	Address:		08-00-2B-00-2B-02
LAT Protocol:	V5.2	Data Link Frame Size: 1500
