Graceful Shutdown

Interfaces on a port are shut down by default (unless you modified the initial configuration).
The Cisco NX-OS software implicitly performs a graceful shutdown in response to either of the following
actions for interfaces operating in the E port mode:
• If you shut down an interface.
• If a Cisco NX-OS software application executes a port shutdown as part of its function.
Description
The port negotiation failed.
The port negotiation failed.
The Fibre Channel domains (fcdomain) overlap.
The assigned domain ID is not valid.
The E port at the other end of the link is isolated.
The port is isolated due to fabric reconfiguration.
The fcdomain feature is disabled.
The zone merge operation failed.
The VSANs at both ends of an ISL are different.
FL ports cannot participate in loop operations. This might
occur if more than one FL port exists in the same loop, in
which case, all but one FL port in that loop automatically
enters nonparticipating mode.
The interfaces belonging to a port channel are down.
The interfaces belonging to a port channel have
incompatible speeds.
The interfaces belonging to a port channel have
incompatible modes.
An improper connection is detected. All interfaces in a
port channel must be connected to the same pair of
switches.
