Congestion Detection, Avoidance, and Isolation
Description
Represents the total number of invalid words received
by a port.
Represents the total number of link failures
encountered by a port.
Represents the total number link reset primitive
sequence received by a port.
Represents the total number of link reset primitive
sequence transmitted by a port.
Receives frame rate in bytes per seconds.
Represents the number of times a port encountered
laser or signal loss.
Represents the number of times a port has transitioned
to an operational up state.
Represents the number of times a port experienced
loss of synchronization in RX.
Increments by one if there is no transmit
buffer-to-buffer credits available for a duration of 100
ms.
Represents the total number of frames dropped at
egress due to congestion timeout or no-credit-drop
timeout.
Represents the transmit frame rate in bytes per
seconds.
Represents the total number of frames dropped at
egress due to timeout, abort, offline, and so on.
Represents the number of times slow port events were
detected by a port for the configured slowport-monitor
timeout. This is applicable only for generation 3
modules.
Captures average credit delay (or R_RDY delay)
experienced by a port. The value is in milliseconds.
