| Description | The value of this object is used to specify the Tx Test Pattern
in an IMA group loopback operation. A value in the range 0 to
255 designates a specific pattern. The distinguished value of
-1 specifies that the implementation may choose the value. In
this case, the implementation may also choose the value of
'imaGroupTestLinkIfIndex'.
It is recommended that the specific value 255 not be used for
testing, since by (R-137) the IMA interface is required to
transmit 0xFF (i.e., 255) when the incoming test command is
inactive or the test link is not detected, and thus it cannot
be established for certain whether 255 was received due to an
actual loopback operation or due to the normal operation of an
IMA that is not performing (or else cannot perform) the test
pattern procedure. |
