■
Link resets Tx—The number of link reset protocol frames
received/transmitted by this port from/to the attached device. The switch
transmits a link reset to initiate the link reset protocol or recover from a link
timeout. This occurs normally to establish BB_Credit on any port in order to
recover lost BB_Credit.
■
LIPS detected—A loop initialization primitive was detected, which means
the loop was completed.
■
LIPS generated—A loop initialization primitive was created to initialize a
loop.
Traffic Statistics
This section describes the types of statistics that display when you click a port’s
bar graph:
■
Link Utilization % Rx and Link Utilization %Tx—There is a separate
value for receive link utilization and transmit link utilization. The larger of
these two values displays on the bar graph.
The current link utilization for the port is expressed as a percentage. This
statistic shows the percentage of the maximum link utilization currently being
used. (If the port speed is 1 Gb/s, the quantity of the maximum link utilization
is 100 MB. If the port speed is 2 Gb/s, the quantity of the maximum link
utilization is 200 MB.) Link utilization is calculated over one-second
intervals. The maximum link utilization is 100%.
■
Frames Rx—The number of frames that the port has received.
■
Frames Tx—The number of frames that the port has transmitted.
■
Four Byte Words Rx—The number of words that the port has received.
■
Four Byte Words Tx—The number of words that the port has transmitted.
■
Flows rerouted from ISL—The number of Fibre Channel traffic flows that
were rerouted from this ISL to another ISL due to congestion. This value
increments only if the OpenTrunking feature is installed. A value would
display only if this port is connected to an ISL.
■

rerouted to this ISL from another ISL due to congestion. This value
increments only if the OpenTrunking feature is installed. A value would only
