CLI command modes :


Switch #

Exec mode :enables temporary changes to terminal settings ,perform basic tests,display system info.

Changes made in this mode are generally not saved across system resets.

Switch(config)#

configuration mode :enables configuration of features that affect the system as a whole .Chnages made on tis mode are saved acrosssystem resets.

To obtain a list of available commands use ?


NO form of commands :

Issue the no form of any commands to perform the following actions:

1.Undo wrongly issued command

2.Delete a created facility

 eg:delete a previouslt created zone.

eg: # no member pwwn 1:2:3:4:5
    # no zone name test vsan 1


 1. Turn the port on and give it a description:

SAN01# config t

Enter configuration commands, one per line.  End with CNTL/Z.

pacdcmdsa3(config)# interface fc4/30

pacdcmdsa3(config-if)# no shutdown

pacdcmdsa3(config-if)# switchport description deploy01

pacdcmdsa3(config-if)# exit

pacdcmdsa3(config)#

pacdcmdsa3# copy running startup

[########################################] 100%

2 .create VASN &Add the port to a vsan:

pacdcmdsa3# config t

Enter configuration commands, one per line.  End with CNTL/Z.

pacdcmdsa3(config)#vsan database

pacdcmdsa3(config-vsan-db)# vsan 10

pacdcmdsa3(config-vsan-db)# vsan 10 name test_vsan_10

pacdcmdsa3(config-vsan-db)#end

# show vsan 10




pacdcmdsa3# config t

Enter configuration commands, one per line.  End with CNTL/Z.

pacdcmdsa3(config)#vsan database

pacdcmdsa3(config-vsan-db)# vsan 10

pacdcmdsa3(config-vsan-db)# vsan 10 interface fc4/30

Traffic on fc4/30 may be impacted. Do you want to continue? (y/n) y

pacdcmdsa3(config-vsan-db)# exit

pacdcmdsa3(config)#

3 .Make pwwn alias:


pacdcmdsa3# config t

Enter configuration commands, one per line.  End with CNTL/Z.


pacdcmdsa3(config)# fcalias name deploy01 vsan 10


pacdcmdsa3(config-fcalias)# member pwwn 21:00:00:e0:8b:8f:e9:7e


pacdcmdsa3(config-fcalias)# exit

4 .Create the zone:

pacdcmdsa3# config t

Enter configuration commands, one per line.  End with CNTL/Z.


pacdcmdsa3(config)# zone name deploy01 vsan 10

pacdcmdsa3(config-zone)# member fcalias deploy01

pacdcmdsa3(config-zone)# member fcalias nsd05-r1

pacdcmdsa3(config-zone)# member fcalias nsd05-r2

pacdcmdsa3(config-zone)# exit

pacdcmdsa3(config)# exit

pacdcmdsa3#

View the zone:

pacdcmdsa3 # show zone name deploy01              

zone name deploy01 vsan 10
  fcalias name nsd05-r1 vsan 10
    pwwn 20:14:00:a0:b8:11:33:d0
 
  fcalias name nsd05-r2 vsan 10
    pwwn 20:24:00:a0:b8:11:33:d0
 
  fcalias name deploy01 vsan 10
    pwwn 21:00:00:e0:8b:8f:e9:7e


5 .Add the zone to a zoneset:

pacdcmdsa3# config t

Enter configuration commands, one per line.  End with CNTL/Z.

pacdcmdsa3(config)# zoneset name san01_prod10 vsan 10

pacdcmdsa3(config-zoneset)# member deploy01

pacdcmdsa3(config-zoneset)# exit

pacdcmdsa3(config)#

Check the zoneset name. Grab the name from the first line of output from:


pacdcmdsa3# show zoneset

zoneset name san01_prod10 vsan 10

6. Activate the zoneset


pacdcmdsa3# config t
Enter configuration commands, one per line.  End with CNTL/Z.

pacdcmdsa3(config)# zoneset activate name san01_prod10 vsan 10

Zoneset activation initiated. check zone status

pacdcmdsa3(config)# exit

pacdcmdsa3# copy running startup

pacdcmdsa3#


7 .Add a user to the cisco mds with network-admin privileges.


pacdcmdsa3# config t

Enter configuration commands, one per line.  End with CNTL/Z.

pacdcmdsa3(config)# username username password password role network-admin

pacdcmdsa3(config)# snmp-server user username network-admin auth md5 password

pacdcmdsa3(config)# exit

pacdcmdsa3# copy running startup
[########################################] 100%

pacdcmdsa3#

8. When attaching symmetrix to your switches its best practice to hard set the ports to 4gb.


pacdcmdsa3(config-if)# int fc3/18

pacdcmdsa3(config-if)# switchport speed 4000

switchport speed auto

9. Rename Fibre Channel aliases using the fcalias rename command like this:

switch(config)# fcalias rename <old alias> <new alias> vsan 10

You can also rename zones:

switch(config)# zone rename <old zone name> <new zone name> vsan 10

And you can rename zonesets:

switch(config)# zoneset rename <old zoneset name> <new zoneset name> vsan 10

10. Search for  thread

switch# show zone | include server-name

pacdcmdsa3# show flogi database|include 21:00:00:24:ff:06:84:cb  (works like grep)

11. Set mode

mds-switch-1# conf t
Enter configuration commands, one per line. End with CNTL/Z.
mds-switch-1(config)# interface fc 1/1
mds-switch-1(config-if)# switchport mode E
mds-switch-1(config-if)# end

12. configure domain ID :

 Configure the switch in  vsan 10 to request a preffered domain 3 and accept any value assigned by the principal switch.


mds-switch-1(config)# fcdomain domain 3 preffered vsan 10

configure the switch in vsan 10 accept only a specific value and moves the local interfaces in vsan 10 to an isolated state if the requested id is not granted.

mds-switch-1(config)# fcdomain domain 3 static vsan 10

Valid domain IDs are numbers between 1-239


13.Configure priority 25 for the local switch in VSAN 10

mds-switch-1(config)# fcdomain priority 25 vsan 10


14 name server statistics

show fcns statistics

15. Rename switch

   # config t
   # switchname newname
   # exit
   # show switchname

16. set speed auto for 3 interfaces

   # config t
   # interface fc1/1 ,fc1/2,fc1/3
   # switchport speed auto
   # no shutdown
   # exit

show interface brief
show logging info
show logging last 10
show running-config diff
show startup-config
show tech-support brief
show version
show zoneset
