Graceful Shutdown

Interfaces on a port are shutdown by default (unless you modified the initial configuration).
The Cisco SAN-OS software implicitly performs a graceful shutdown in response to either of the
following actions for interfaces operating in the E port mode:
•
•
A graceful shutdown ensures that no frames are lost when the interface is shutting down. When a
shutdown is triggered either by you or the Cisco SAN-OS software, the switches connected to the
shutdown link coordinate with each other to ensure that all frames in the ports are safely sent through
the link before shutting down. This enhancement reduces the chance of frame loss.
A graceful shutdown is not possible in the following situations:
•
•
•
Note This feature is only triggered if both switches at either end of this E port interface are MDS switches and
are running Cisco SAN-OS Release 2.0(1b) or later.

Setting the Interface Administrative State

To disable or enable an interface using Fabric Manager, follow these steps:
Step 1 Either expand Switches > Interfaces and then select Gigabit Ethernet or expand Switches > Interfaces
and then select FC Physical. You see the interface configuration in the Information pane.
Step 2 Click the General tab.
Step 3 Click Admin.
You see the drop-down box shown in
Figure 20-3
Step 4 Set the status to down (disable) or up (enable).

If you shut down an interface.
If a Cisco SAN-OS software application executes a port shutdown as part of its function.
If you physically remove the port from the switch.
If in-order-delivery (IOD) is enabled (see
If the Min_LS_interval interval is higher than 10 seconds ().
