tcpip sh dev/fu and sda>tcpip sh dev/fu

[labadie_1]

Hello

Alpha Vms 7.3-2, Tcpip 5.4 Eco 5 and Tcpip 5.4 Eco 6

$ tcpip sh dev/fu bg1201 shows some values for the lines
Bytes transferred
and
I/O Completed, in the column "SEND"
while
$ ana/sys
tcpip sh dev/fu bg1201
always shows 0 in the same column.

Known bug ?
By the way, the I/O completed value, for the column "RECEIVE", is completely different, may be some different unit is used ?

Here is what I get

$ tcpip sh dev /fu bg1201

On vms 7.3 AND tcp 5.3 ECO 2.

tcptrace reveils traffic on the ucx device in both direction. But ucx sho dev bg only shows received bytes and IO's completed. Send stays zero.

Ana/sys shows the same info. In a check of about 10 random ports all the data was +- identical.

Fwiw

Thanks Wim

May be it is "normal"/a feature...
:-)

You are observing two bugs, and
they will never get fix unless someone
raises a problem report to engineering.

Some fields in the BG ucb were promoted
from word to longword size. The sensemode
code was never updated to account for this
and as a result fields such as "I/O waits",
"I/O completed" are wrapping at 65536.

Some fields in the BG ucb were moved. The
sensemode code was never updated to account
for this and as a result these fields will
display as zero.

You can trust the SDA extension, _after_
version V5.6.

Thanks Steven for the info.

This answers completely this thread.

For reference: this problem (wrong counter values in TCPIP SHOW DEVICE/FULL) has been escalated as QXCM1001433191 against TCPIP V5.7 ECO 5
