| Description | This table contains the network element view of optical patches
between two interfaces on the same network element.
It is up to the user to keep the provisioned information that
is reflected in this table in sync with the actual patches
present between interfaces on the network element.
Provisioning of a patch in this table does not cause a patch to
be inserted; it only informs the network element that a patch
has been, or is soon to be, added or removed.
Each entry in the table models a unidirectional or
bidirectional patch between two interfaces on the same
network element. When one interface is patched to two
different interfaces, one in the receive direction and
the other in the transmit direction, the interface will
appear in two different entries in the table.
The terms low and high are chosen to represent numerical
ordering of the two interfaces associated with a patch. That
is, the interface with the lower value of ifIndex is termed
'low', while the other interface associated with the patch is
termed 'high'. |
