USER’S GUIDE

340 CyberSWITCH

Some of these <SYS> packets are overloaded in that they are not just keep-alive packets but are

control packets needed for the application to run successfully and hence have to be routed like

regular SPX data packets. If any NetWare application does not seem to work across WANs, it may

be because of the mishandling of these <SYS> packets and can be traced by disabling SPX keep-

alive spoofing.

This above described implementation is followed for keep-alive packets received over the LAN and

the WAN. If a keep-alive is received over the WAN and it is determined that a spoofed keep-alive

should be generated, it will be returned over the same WAN connection on which it was received.

The parameters for SPX spoofing are configured for each device. The SPX spoofing option can be

enabled or disabled. By default the option is enabled. When disabled the SPX keep alives are routed

without any special handling. If the option is enabled the SPX spoofing duration time T is specified

in minutes. The default is set to 120 minutes.
