Licensing Tips for Cisco 3750 Stacks
Recently I had to upgrade some 3750-x Stacks to Advanced Services and the Cisco documentation was a bit short of advice, and certainly not all in the one place. So here is a quick run down of some key steps.
Before you start.
Go to your 3750 stack and pull off ìshow versionî take a copy of the output to the internet enabled system you are going to access Cisco from. To get Advanced Services you will need to have the universal version of IOS installed on the switch, and the Advanced Services are only enabled once the appropriate license is installed and the switch reloaded.
Go/License
Once you received a your PAK though email go http://www.cisco.com/web/go/license as instructed in the pack.
Once you are through your CCO logon you should be presented with the following screen.
If you have multiple licences available you can only select 1 at a time, enter 1 in [Qty] box
then click [All Done]
Product License Registration
This should take you to the next page where your “show version” will come in handy.
So looking at this page you need product number and serial number, now look at “show version” and you will have several options to choose from.

So the information you need for each switch is:
Model number : WS-C3750X-48PF-S =Product number
System serial number : FDO******** = Serial number
If you accidentally use another serial number e.g. of the motherboard then it will still generate a license file but will not install in the switch.
Copy The Lic file to corresponding flash in the stack
I have not seen any guidance directly from Cisco, but there is some mention on the forums (https://supportforums.cisco.com/thread/2055932) This makes a lot of sense to me keeping the license file tied to the specific switch. I would even consider it as best practise, but who am I to state this.
Copy each individual .lic file to the corresponding switches in the stack’s flash. In case you don’t know each switch in the stack has its own flash that can be access by using the switch number in the flash: command so switch 1 flash = flash1: and switch 2 =flash2:
copy ftp://johnmcmanus:[email protected]/Licenses/ABC-1-1-SW-1/FDO_lostofcharacters.lic flash1:FDO_lostofcharacters.lic
copy ftp://johnmcmanus:[email protected]/Licenses/ABC-1-1-SW-2/FDO_lostofcharacters.lic flash2:FDO_lostofcharacters.lic
Install the License
license install flash:flash1:FDO_lostofcharacters.lic
license install flash:flash2:FDO_lostofcharacters.lic
You will need to reboot for the license to take effect, use “show version” this will display

In summary
I had trouble finding all the information in one place when looking to upgrade my 3750′s licenses, so here are my tips for obtaining and installing licenses on 3750 stacks.
