Bypassing Ports
71
Changing LIP F8 and LIP F7 Settings
To use the command-line interface to bypass a port when a LIP F8 error is generated, a
user with administrator privilege enters
Server>>change hub port [
port
|
all
] lipf8 enable
This setting is the factory default.
To disable the LIP F8 bypass and return the port to the loop, a user with administrator
privilege enters
Server>>change hub port [
port
|
all
] lipf8 disable
To use the Internet browser interface for LIP F8 or AutoLIP bypass, click Setup in the
menu bar, and then click Hub Setup; see Figure 5-8. In this screen, click check boxes as
follows:
•
AutoBypass during LIP F8 automatically excludes the port from the loop while it is
streaming LIP F8 characters (which indicate that the attached device is not receiving
a valid signal), and reinsert it if it becomes stable again.
This box is checked (on) by factory default. Three consecutive LIP F8 sequences
from a port disable the entire loop.
•
AutoLIP (Originate LIP F7 on Insertion) automatically reconfigures the loop when a
hub port becomes active.
This box is checked (on) by factory default.
For more information on the LIP F8 and LIP F7 characters, see “Fault and Error
Management” on page 12 in Chapter 1.
