Table 6-1 defines some of the USCM congestion parameters that appear in the
following sections.
Table 6-1. USCM Congestion Parameters
Parameter Valid Values
Link Event Type
(Link Integrity Notification ELS)
The port exceeded the error transmission
threshold. Valid values are:
Unknown
Link Failure
Loss-of-Synchronization
Loss-of-Signal
Primitive Sequence Protocol Error
Invalid Transmission Word
Invalid CRC
Device Specific
Delivery Notification
(Delivery Notification ELS)
The port discarded the frame because the
delivery time threshold was exceeded. Valid
values are:
Unknown
Timeout
Unable to route
Device Specific
Congestion Notification
(Congestion Notification ELS)
The transmission resources have been con-
sumed to a level low enough to cause the
receiving device—this port—to behave as
though it is congested. Valid values are:
Warning
Congestion is building.
Alarm
Congestion has reached a severe level.
Peer Congestion Event Type
(Peer Congestion Notification ELS)
Another port in this zone is exhibiting behav-
iors associated with I/O congestion, which is
impeding a free flow of frames through the
Fabric. Valid values are:
Clear/None
Lost Credit
Credit Stall
Oversubscription
Device Specific
