| Description | This object is used to designate an interface as the test link
for use in the Test Pattern Procedure. The distinguished value of
zero specifies that the implementation may choose the Test Link,
in which case, the implementation may also choose the value of
'imaGroupTestPattern'. The value zero may also be used if no link
has yet been added to the group.
Note that this value is NOT the same as the Tx LID value, but
instead either identifies the ifIndex value of the test link to be
used by the Test Pattern Procedure (i.e., the link whose LID value
is inserted in the Tx LID field of the transmitted ICP cells),
or identifies that the implementation may choose the test link (if
the value is zero). |
