Chapter5 Configuring Transponder Line Card Interfaces
About Cross Connections
Note The error field in the show patch command output helps troubleshoot shelf misconfigurations. When
there is a channel mismatch between a transponder line card and a OADM module, “Channel
Mismatch” appears for the patch connection. When more than one OADM module drops the same
channels, “Channel Mismatch” appears for all patch connections.
Example
The following example shows the patch connections:
Switch# show patch
