Cisco MDS Cheat Sheet

A more complete set of commands for use on MDS switches, with a useful set of commands at the top for exporting useful information (by logging session output of PuTTY terminal).  Note that using a ? after any command will show possible commands.

Export useful information

show switchname (display hostname on network)

show flogi database (shows wwn of fc connected hosts logged in to the switch ports)

show vsan (display vsans configured)

show zone vsan 10 (display zones in vsan)

show zoneset vsan 10 (display zoneset, zonenames and wwns in zones)

show fcalias vsan 10 (display human friendly alias for each wwn in all zones in vsan 10)

ENABLE A NEW PORT

Before you can create your zones, the device connected to the fc switch will need to flog in so you can see its wwn.  Before it can do that, the port itself will need to be opened/enabled.

conf t

interface fc1/21       (where 21 is the port number)

no shutdown           (obviously!)

exit

ZONING

If you have to do some CISCO zoning at the command line here are a few of my favorite commands;

original cisco doc here

To create an alias:

conf t
fcalias name {alias_name} vsan {vsan number}
member pwwn {wwid}
exit

To create a zone:
conf t
zone name {zone _name} vsan {vsan_number}
member {alias_name}
member {alias_name}
.
.
exit

To add it to the zoneset:
conf t
zoneset name {zoneset_name} vsan {vsan_number}
member {zone_name}
.
.
exit

To activate the zone/zoneset:
conf t
zoneset activate name {zoneset_name} vsan {vsan_number}
exit

Save the configuration
copy running-config startup-config

Displaying Zone Information

You can view any zone information by using the show command. If you request information for a specific object (for example, a specific zone, zone set, VSAN, alias, or even a keyword like brief or active), only information for the specified object is displayed. If you do not request specific information, all available information is displayed. Table 4-1 lists the show commands and the information they display.
