Conguring the Bypass Switch
This Bypass Switch allows you to set several conguration options and to
display conguration information. You can set:
The frequency of the heartbeat.
This denes the period of time that passes before the switch
considers the packet to have timed out. The default is 1 second.
The number of timeouts allowed.
This is the number of packets missed before the switch bypasses
the IPS (retry count). The default is 3 missed packets.
Port communication parameters.
You can turn Link Fault Detect and Bypass Detect on or off.
The default is LFD and Bypass Detect off.
A custom heartbeat packet.
You can input a custom heartbeat packet to suit special needs. The
default is the IPX packet shown on page 5.
Fail Mode:
Fail Open - when in Bypass state, data is routed from Port A to B
Fail Closed - when in Bypass state, ports A and B are shut down
Reset to factory defaults.
Use this option to quickly restore the original conguration.
For quick reference, you can display the conguration settings and heartbeat
packet.
