Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 5.2(2d) (OL-25090-04 A0, April 2012)

15 MDS 9000 Series Multilayer Director & Multilayer Fabric Switches Release Notes
You must use the serial interface to configure a switch IP address. Refer to the Cisco MDS 9000 Family
Configuration Guide for instructions on how to connect the serial port to a host machine.
INITIAL INSTALLATION
RECOMMENDATIONS/REQUIREMENTS
The C-series MDS 9000 Family of switches does not automatically allow SAN connectivity for the first-
time, out-of-the box power up. For more comprehensive initial setup information, please refer to the
Cisco documentation found at http://www.cisco.com.
Note: The setup dialog prompts for all of the necessary settings.
The following steps must be taken during the first-time setup:
I. To enable all ports on the switch, set the ports to noshut – by default, all switch ports are set to shut
During the setup command:
Configure default switchport interface state (shut/noshut) [shut]: noshut
II. To allow traffic flow to all members of a default zone, set the default zone to permit connectivity – by
default, zoning is set to deny
During the setup command:
Configure default zone policy (permit/deny) [deny]: permit
III. If upgrading from SAN-OS 1.3(4a) or earlier, enable FCID persistence for all VSANs on the switch –
FCID persistence is enabled by default starting with SAN-OS 2.0(1b) and NX-OS.
Enable persistent FCID for each VSAN using the CLI dialog as follows:
switch# config terminal
switch(config)# fcdomain fcid persistent vsan 1
switch(config)# exit
switch# copy running-config startup-config
In this example, the number 1 at the end of the line is the name of the default VSAN ID. If additional
VSANs were created, you must repeat this command for each additional VSAN. For example, if you
added two more VSANs with ID numbers 2 and 3, you must enter the following commands:
switch# config terminal
switch(config)# fcdomain fcid persistent vsan 2
switch(config)# fcdomain fcid persistent vsan 3
switch(config)# exit
switch# copy running-config startup-config
IV. Enable In-Order Delivery of Frame
During a steady-state environment, the hardware and software architecture of the C-series MDS 9000
Family prevents out-of-order (OOO) frame distribution from occurring. If the fabric encounters a
failure, some devices may not be able to handle any OOO frames. For this reason, HP requires in-
order delivery (IOD) be enabled for all switches. There is a switch setting to enable in-order of
frames during fabric failure.
