IST2396I

Explanation
VTAM® issues
this group of messages in response to a DISPLAY TRL,TRLE=trlename,DEVSTATS
command when trlename represents an IBM® 10GbE RoCE Express® interface.
A
complete description of the message group follows:IST2396I RNIC STATISTICS FOR trlename
IST2397I DESCRIPTION OVERFLOW COUNT
IST2398I description overflow count
...
IST314I END

Many of the statistics reported using
message IST2398I have both a count and an overflow. Both the count
and overflow are maintained in unsigned 32-bit variables (unless otherwise
indicated). Because an unsigned 32-bit variable can contain only a
value up to and including 4294967295 ('FFFFFFFF'X), the variable will
wrap through 0 if an increment results in exceeding this value. When
such a wrap occurs, the overflow is incremented by 1. Therefore, the
total count is determined as follows: Total = (overflow * 4294967296) + count

IST2396I
This
is the first message in the message group. 
trlename
The name of the resource that was specified on the DISPLAY TRL
command. Use this value to correlate the 10GbE RoCE Express statistics in this message group
with the message group IST2361I output generated by the DISPLAY TRL,TRLE=trlename command. 

IST2397I
This message is a header message
for the statistics displayed with message IST2398I.
IST2398I
This
message displays the number of occurrences for the statistic described
by description. The possible combinations of overflow, count,
and description are:
INBOUND FRAMES DROPPED = overflow countRepresents
the number of inbound Ethernet frames that were dropped on this 10GbE
RoCE Express interface.

INBOUND FRAME ERRORS = overflow countRepresents
the number of             inbound Ethernet frames that had errors
on this 10GbE RoCE Express interface.
Restriction: This value is always
0 when the 10GbE             RoCE Express adapter
operates in a shared RoCE environment.

INBOUND RDMA FRAMES = overflow countRepresents
the number of Ethernet frames received on this 10GbE RoCE Express interface.

INBOUND RDMA OCTETS = overflow countRepresents
the number of Ethernet octets received on this 10GbE RoCE Express interface.

OUTBOUND FRAMES DROPPED = overflow countRepresents
the number of outbound Ethernet frames that were dropped on this 10GbE
RoCE Express interface.

OUTBOUND FRAME ERRORS = overflow countRepresents
the number of             outbound Ethernet frames that had errors
on this 10GbE RoCE Express interface.
Restriction: This value is always
0 when the 10GbE             RoCE Express adapter
operates in shared RoCE environment.

OUTBOUND RDMA FRAMES = overflow countRepresents
the number of Ethernet frames sent on this 10GbE RoCE Express interface.

OUTBOUND RDMA OCTETS = overflow countRepresents
the number of Ethernet octets sent on this 10GbE RoCE Express interface.

LINK OUTAGE NOTIFICATIONS = overflow
      countRepresents the number of times that VTAM was notified of lost connectivity
      to the 10GbE RoCE Express port.
