Hi Ibrahim,
When you say switch hang do you mean that switch doesnt boots up at all ? or does it gets hang while you are configuring it ?
Does it comes up after some time or doesnt comes up at all ?

Hi Ibrahim,
What I understand is that you have Catalyst 3750 stack each other, and you have removed one of them from stack but
still you want to use it with default configuration.
You don't need to to erase the configuration - you can just switch off the stack member you wish to remove, and then
unprovision it using the command:
no switch
Example:
To remove switch number 2 from a stack. The model number of the switch is WS-C3750G-48T:
3750(config)# no switch 2 provision ws-c3750g-48t
3750(config)# exit
3750# write memory
Hope this helps you.

Hi
what the below command means:
switch 1 provision ws-c3750-48ts
switch 2 provision ws-c3750-48ts
now i wanna add switch 3 to the stack, what do i nned to add on the master switch based on the output below,Please help line by line coz am scared when i add the new switch the network vlan users complain
3750#sh switch detail

Hi Ibrahim,
For adding a switch to the stack follow these steps:
Step 1) On the new switch give the global command: switch stack-member-number provision type
Where Type is the type of switch you are adding to the stack.
When adding for example a third Cisco switch to the Cisco stack, use the following command:
switch 3 provision ws3750g-24t
Step 2) Power off the new stack member
Step 3) Connect the new member to the Cisco stack using the stacking cables, 1 loop at a time.
Step 4) Power on the new stack member. The switch will come alive and will receive the Cisco IOS version from the master, when that is completed it will be ready to service network requests.
For removing a member switch from the stack use the following steps:
Step 1) Power off the stack member to be removed.
Step 2) Remove the stackwise cable from the switch.
Step 3) Issue the following command on the stack master: no switch stack-member-number provision type
Background
Cisco StackWise technology is a stacking architecture optimized for Gigabit Ethernet with 32-Gbps interconnect throughput. Cisco StackWise technology unites up to 9 individual Cisco Catalyst 3750 switches into a single logical unit, using special stack interconnect cables and stacking software. The stack behaves as a single switching unit that is managed by a master switch elected from one of the member switches. The master switch automatically creates and updates all the switching and optional routing tables. A working stack can accept new members or delete old ones without service interruption.
Also see the below link for Creation and Management of Catalyst 3750 Switch Stacks.
http://www.cisco.com/en/US/products/hw/switches/ps5023/products_configuration_example09186a00807811ad.shtml#conf
Finally I would suggest you to do this task in off working hours as it seems your setup is critical as you are getting vlan users complaints.

Hi Ibrahim,
Correct step by step procedure is available at:
Change the switch priority of the switch to be added to "1".
switch stack-member-number priority new-priority-value
Note: This step is optional, but it will make sure that the switch has fewer chances to become a stackmaster in the future.
Power off the switch that is to be added.
Make sure that the stack is fully connected so that, when you connect the new switch, the stack will be at least in half connectivity and does not partition.
Connect the new switch to the stack with the StackWise ports.
Power on the newly added switch.
After the new switch comes up, issue the command show switch to verify stack membership.
connect the stack cable as shown below:

Shashank

And also here is another step by step procedures for you.....
This is mostly simple to do, but there are several checks to make along your journey, and hopefully I can point them out clearly.
ZZStack#show switch stack-ring speed Stack Ring Speed : 32G Stack Ring Configuration: Full Stack Ring Protocol : StackWise
See this publication for stack-wiring help:
http://www.cisco.com/en/US/docs/switches/lan/catalyst3750/hardware/quick/guide/3750GSG3.html#wp49279
ZZStack#show switch stack-ring speed Stack Ring Speed : 32G Stack Ring Configuration: Full Stack Ring Protocol : StackWise
ZZStack#show switch Switch/Stack Mac Address : 0024.9803.8e80 H/W Current Switch# Role Mac Address Priority Version State ---------------------------------------------------------- *1 Master 0024.9803.8e80 15 0 Ready 2 Member 0023.ac0f.7880 1 0 Ready 3 Member 001a.e267.0080 1 0 Version Mismatch
In this example switch 3 was added to the stack, the stack ring looks good, but on the switch status output, instead of saying “Ready” it says “Version Mismatch.” You now need to ensure your switch gets the same IOS version as its stack-mates and reboots for this to take effect(see below).
If your stack says your new switch is in the “Ready” state, you are in luck and you are done! (except for configuring your new user ports)
To check to see if its working or not, check the log. If you see log entries resembling any of the below, it appears automatic upgrade is working as it should.
ZZStack#show log ---snip--- Nov 24 16:58:36.388 EST: %IMAGEMGR-6-AUTO_COPY_SW_INITIATED: Auto-copy-software process initiated for switch number(s) 3
This shows that it has started the auto upgrade process. You can check the status with the “show archive status” command or by continually checking the log.
If you see the below it was successful and is now rebooting this member switch so the correct IOS loads and it can finally join the stack as it should(and you should be done):
---snip--- Nov 24 17:06:04.453 EST: %IMAGEMGR-6-AUTO_COPY_SW: Software successfully copied to Nov 24 17:06:04.453 EST: %IMAGEMGR-6-AUTO_COPY_SW: system(s) 3 Nov 24 17:06:04.453 EST: %IMAGEMGR-6-AUTO_COPY_SW: Done copying software Nov 24 17:06:04.453 EST: %IMAGEMGR-6-AUTO_COPY_SW: Reloading system(s) 3
If you don’t see any of the above log entries, go on to the next step.
If you made it to this step, it probably means there is a featureset mismatch(or some other problem) and you need to force this new member to take the IOS version that the stack is currently running. In this scenario, even the “archive copy-sw” command does not work, so you must either load the IOS bin file manually or use use the appropriate “archive download-sw” command with the “/allow-feature-upgrade” switch to load the IOS to the ENTIRE STACK again, including this new member(but you only need to reboot the new member). I prefer to use the archive command, its slow but its so easy!

Hi Guys
on the Master Switch do i need to configure the provision the 3rd swotch which to be added to the Stack
I have the below on the master switch,is okay to add switch 3 provision ws-c3750-24ts
switch 1 provision ws-c3750-24ts
switch 2 provision ws-c3750-24ts

you don't need to from what i have seen. Normally once the new switch becomes part of the stack , the master adds this by itself as it knows that its the 3rd switch in the stack. Alteast, thats what i have seen. However, when you remove the switch from the stack it doesnt automatically remove it . you have to manualy tell the master switch by typing "no switch 3 provision ws-c3750-24ts"
Just make sure that the IOS is the same on the new switch like that of the switches in the stack.

I am having the same issue. I can not recreate the stack because got this switch 3750 12S fiber out of storage to use as a replacement. When booting up, this is what I get and it doesn't progress any farther no matter how long I let it sit.

I cannot run the no switch command mentioned earlier in this post and I am stumped as to how to proceed. I've tried wiping the switch so the IOS can be upgraded. It sits at, switch:, and will not flash_init.
Any suggestions, please.

If you can't do anything, check your console terminal to make sure all the settings are correct.
If they are, try a different client.
05-07-2013 10:01 PM
Thanks, leolaohoo.
It still does the same thing. I've used putty, hyperterm and secure crt with the same results.
05-07-2013 10:30 PM
Ok, so you used different softwares to console. What about the settings? Did you make sure that that you have 9600-8-none-1 and flow control is OFF?
