Bypassing a Wavelength on page 25
The IPLC enables you to optically bypass a wavelength by entering a few simple
configuration statements. Bypassing a wavelength does not terminate the wavelength
at the local IPLC but instead passes the wavelength on to the next downstream IPLC
node. Optical bypasses are software configurable and controlled through the IPLC's
wavelength selective switch (WSS) so there is no need for manually swapping cables
or other manual intervention. The IPLCs software optical bypass enables wavelengths
that do not terminate on the given node to be passed-through to the remote IPLC node
without optical-electrical-optical (OEO) conversion.
You can use this procedure to manage express traffic at intermediate, two-degree IPLC
nodes. This topic describes how to bypass a wavelength on the IPLC module.
NOTE: Bypassing wavelengths is supported only on IPLC two-degree nodes
running express traffic. For more information, see
Node for Express Traffic" on page
Before you begin, configure the IPLC two-degree intermediate node for express traffic.

To configure the IPLC to bypass a wavelength:
Access the IPLC configuration hierarchy and specify the wavelength you want to
