for the default settings for each Smart Setting.
LIP Control
Methods of change notification management.
• rxtxlip – no change notification management
• rxlip – devices attached to the port can receive
change notifications but will not propagate change
notifications generated by that port to other ports.
Note:
Change notifications will be reflected back out of
the port if originated by devices attached to this
port.
• txlip – propagates change notifications generated by
the port to other ports but will not allow devices
attached to the port to receive change notifications
from other ports.
• nolip – blocks change notifications from being
propagated from the port and change notifications
from devices on other ports to devices on the port.
• Managed –
Note:
This setting should not be used
unless directed to do so by a customer service
representative.
Bypass on OS Error Policy
Ordered set (OS) errors are detected and counted for
each individual port. When this policy is enabled, a port
is bypassed when its OS count exceeds the threshold
setting. The threshold setting is based on the number of
ordered set errors identified in 10 seconds.
Note:
This threshold setting can be adjusted.
Bypass on CRC Error Policy
Cyclic Redundancy Check (CRC) errors are detected
and counted for each individual port. When this policy is
enabled, a port is bypassed when its CRC count
exceeds the threshold setting. The threshold setting is
based on the number of CRC errors identified in 10
seconds.
User intervention is required to return the port into the
zone. Recovery methods include replacing the defective
component, cycling power to the device on the port,
removing and reinserting the bypassed port, or cycling
power to the switch.
Note:
This threshold setting can be adjusted.
Bypass on Clock Delta
Policy
The switch determines the relative frequency of the
signal being received by a port to the internal switch
clock. The result of this test allows the determination of
how far apart in frequency the switch’s clock is in
relation to the clock of the received signal – the clock
delta. If the clock delta exceeds a set threshold, the
switch is notified and the port may be bypassed if
necessary. Typically, clock drift is slow enough to allow
the removal and replacement of a defective part before
the defective part begins to affect system performance.
