HST-3000 Ethernet Testing User’s Guide
When trying to loop
up an instrument on
the far end using a
loop up command,
the loop up fails.
HSTs running older software
releases so not support
user-defined TPIDs. The lat-
est HST software release
allows you to specify a
user-defined TPID.
As a result, if you issue a
loop up command from an
HST with a user-defined
TPID, the receiving HST
(running an older version of
software) will not respond to
the loop up command.
This will also occur when
running Ping tests, or
RFC 2544 tests with differ-
ent SVLANs or TPIDs for the
near and far end instru-
ments.
–
Verify that both HSTs
are running the most
recent software release.
HST software releases
are available at
.
–
Verify that the specified
SVLAN and TPID for
traffic transmitted and
received on both instru-
ments match.
