+                            Fix
+--------------------------------------------------------------------------------
+* IOSXE
+    * Modified ShowCtsInterfaceSchema:
+        * Changed global_dot1x_feature from schema to Optional (not present on port-channel interfaces)
+        * Changed cts mode value from schema to Optional to (not present when cts status is disabled)
+    * Modified ShowCtsInterface:
+        * Updated regex pattern p2 to also match Port-channel interfaces
+        * Updated regex pattern p3 to also match CTS disabled status
+        * Added conditional to cts_dict so mode key is not generated if cts is disabled
+    * Modified golden_output2_expected test data
+        * Added expected output for Port-channel interfaces
