AT-29xx Series Gigabit Ethernet Network Adapters Installation Guide

11.5.x or 6.05.x or 6.0 NetWare 5.x or 6.0 has been successfully installed, set the minimum packet receive buffers parameter in the startup.ncf file to 1500 for each adapter in the system.

Set the maximum packet receive buffers to three times the minimum packet receive buffers. Typically 4 MB of RAM is required per 1000 receive buffers. For more information, see “Verifying or Modifying Adapter Parameters” on page 88.

12.In the autoexec.ncf file, delete the packet receive buffers parameter (RxBuffers=32) in the load statement for this adapter. Deleting the receive buffers phrase from the load statement resets the receive buffers parameter to the default value of 200 for this adapter.

Note

The server needs to be restarted for the new configuration.

Example: The default maximum number of receive buffers for the system is 500; the default minimum is 128. Edit the startup.ncf file to have the following entries. The actual numbers will be a function of the number of ports in the system. The following is an example for a system with 8 ports installed:

set maximum packet receive buffers = 36000

set minimum packet receive buffers = 12000
