Displaying port state (root/diag/ps)
This command displays the port states and conditions for a single port or for all ports.
To view the port state and condition for all ports:
From the Diagnostics menu (root/diag), type
ps
and press E
NTER
.
To view the port state and condition for a specific port:
From the Diagnostics menu (root/diag), type
ps <port number>
and press E
NTER
.
Displaying port clock delta (root/diag/delta)
This command displays the port clock deltas for a single port or for all ports. The port
clock delta is the difference (in parts per million) between the internal clock and the
received clock signal on the port.
To view the port clock delta for all ports:
From the Diagnostics menu (root/diag), type
delta
and press E
NTER
.
To view the port clock delta for a specific port:
From the Diagnostics menu (root/diag), type
delta <port number>
and press E
NTER
.
LIPF8 (F8 Failure) A non-switching port has detected a failure on its receive
input, is notifying other ports, and is determining whether
the network is still operational.
Some events that could cause the port to detect network
failure follow:
• A device has failed.
• A device has been powered off.
• The physical connection between the transmitter and
receiver is broken.
• Activating the port bypass circuit does not typically result
in a network failure.
LIPF7 (F7 Initialization) A port is in the non-participating mode and is attempting to
win arbitration and begin initialization, possibly because the
port was reset or is powering up. Sometimes the port is
sending this sequence to another hot-cascaded switch, like
a new initiator being inserted in the network.
LIP (Change
Notification) A change notification has been detected and action has
been taken.
Unknown The switch cannot determine what is being transmitted.
Invalid An invalid transmit word has been detected.
CRC Error A Frame CRC error has been detected.
PT to PT (Point-to-Point) A point-to-point connection has been detected.
