3750 stack building best practices

Unanswered Question
Nov 17th, 2008

When building a typical stack using the Cisco 3750 is it best to hard set your master and hard set provision your switches? Any good best practices/advice from the field would be greatly appreciated.


I have this problem too.

The simplest option is to auto-provision the switch to the first switch in the stack. The configuration of the second switch can either be auto-provisioned or defaulted when added:-

Take a look at the following document:-


The first thing that you should do it ensure you have copies of your configurations.

Prior to provisioning the second switch, configure the first switch to Master, 'switch 1 priority 5', this will ensure that when you add the second switch it is not elected as Master.

The next step is to auto-provision the switch on this Master switch 'switch 2 provision ws-c3750-48ts' for example.

You will then discover that new ports have been added to the configuration starting 2/0/1 - 2/0/48.

Now you have the choice of auto-provising the configuration, by taking the configuration of the ports on the second switch and overlay them on the new port range.

If you don't do this now, all that will happen is that the second switch when added to the stack will have the default configuration applied to it and then you change the port configuration.

Take a look at a previous post on the same topic:-


Hope this helps.
