Upgraded to 8.4(1) or 8.4(1a) Symptom 1: "Show running-config diff" command shows a difference in the number of lines between the running and startup config.

Cisco bug id CSCvs76682 - Interface "no shutdown" command does not show in the running-config after ISSU 8.4(1) Description Symptom: After upgrade to 8.4(1), "no shutdown" command for the port-channel interfaces display in the startup-config is not shown on the same interface in the running-config. This causes management applications to indicate there is a difference between the port-channel interfaces in the running-config and startup-config. (even though the actual port-channel interface status is correct) Conditions: Upgrade to 8.4(x). Workaround: ISSD to a previous unaffected level ("no shutdown" is not displayed on the port-channel interfaces in either running-config or startup-config.) Further Problem Description: Previous to 8.4(1): "no shutdown" on a port-channel interface was not being displayed in the running-config or startup-config prior to 8.4. On the port-channel interface, config did show in both running-config and startup-config prior to 8.4. In 8.4(x): "no shutdown" interface config statement now shows in the startup config, but not the running-config.... Shutdown interface config statement still does show in both running-config and startup-config.
Workaround: Downgrade code to a previous code level where the issue is not present. ("no shutdown" is not displayed on the port-channel interfaces in either running-config or startup-config.) Fix: Upgrade to NX-OS 8.4.2 or above.
