Setting Description
Port Control The method for controlling a port. Options include:
• auto – the default setting. The switch will automatically insert a port
based on policy settings. This prevents the insertion of incompatible
ports, which may cause disruption.
• bypass – removes a port from the network. Use this mode to keep a
device out of an initialization cycle when troubleshoot ing.
• extLoopback – removes a port from the network and routes the port's
receive signal back through the port's transmitter. Use this mode to
isolate a specific zone for troubleshooting or to te st a transceiver’s
circuitry and attached media from the node end.
• insert – allows ports whose transceivers canno t derive a valid clock
or "K" character (Ordered Set) to join a zone. Use this mode
cautiously – devices without valid characters may put bad data into a
zone, causing the zone to go down.
Bypass on Clock Delta 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 signa l – 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.
