The Cisco SAN-OS software implicitly performs a graceful shut down in response to either of the
following actions for interfaces operating in the E port mode:
•
•
A graceful shut down ensures that no frames are lost when the interface is shutting down. When a shut
down is triggered either by you or the Cisco SAN-OS software, the switches connected to the shut down
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 shut down is not possible in the following situations:
•
•
•
This feature is only triggered if both switches at either end of this E port interface are MDS switches and
Note
are using the Cisco SAN-OS Release 2.0(1b) (or later) software.
To gracefully shut down an interface, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# interface fc1/1
Step 3
switch(config-if)# shutdown
To enable traffic flow, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# interface fc1/1
Step 3
switch(config-if)# no shutdown
Interface Modes
To configure the interface mode, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# interface fc1/1
switch(config-if)#

If you shut down an interface
If a Cisco SAN-OS software application executes a port shut down 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
Information" section on page

Purpose
Enters configuration mode.
Configures the specified interface.
Gracefully shuts down the interface and administratively
disables traffic flow (default).
Purpose
Enters configuration mode.
Configures the specified interface.
Enables traffic flow to administratively allow traffic when
the no prefix is used (provided the operational state is up).
Purpose
Enters configuration mode.
Configures the specified interface.
