Both Priority = 1

[Ibrahim Jamil]

Hi the below confused me as both priority gives us "1" so how switch 1 is master

Switch#  Role   Mac Address     Priority Version  State
----------------------------------------------------------
*1       Master 0027.cccb.7f80     1      0       Ready              
2       Member 6416.8h5f.7f80     1      0       Ready

Here you go dude:

1. The switch that is currently the stack master

   Note: When stacks merge, the elected stack master would have been the master of one of the merged stacks.

   Note: When stacks partition, the stack master of the original stack will be the master of its partition.

2. The switch with the highest stack member priority value

   Note: Cisco recommends that you assign the highest priority value to the switch that you prefer to be the stack master. This ensures that the switch is re-elected as stack master if a re-election occurs.

3. The switch that uses the non-default interface-level configuration

4. The switch with the higher Hardware/Software priority. These switch software versions are listed from highest to lowest priority:

   1. Cryptographic IP services image software

   2. Noncryptographic IP services image software

   3. Cryptographic IP base image software

   4. Noncryptographic IP base image software

   Note: Switches that run Cryptographic or IP services image will take a longer time to load than Non-Cryptographic or IP base image. When you power on or reset an entire switch stack, some stack members will not participate in the stack master election. This is because stack members that are powered on within the same 20-second time frame participate in the stack master election and have a chance to become the stack master. Stack members that are powered on after the 20-second time frame do not participate in this initial election and only become stack members. At times, switches with lower software priority can become the stack master, but all stack members will participate in the stack master re-election.

5. The switch with the longest system up-time

6. The switch with the lowest MAC address

Hi

on the Master Switch do i need to configure the  provision of the 3rd switch 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

to be add switch 3

switch 3 provision ws-c3750-24ts

On the same link I posted before is a section on how to add a swithc to the stack. Follow the stops and you should be fine.

as a summary steps

switch 1 provision ws-c3750-24ts
switch 2 provision ws-c3750-24ts

on the master i ll add the below command, in order to get the same configuration from the master,

switch 3 provision ws-c3750-24ts

so it will be like that:

switch 1 provision ws-c3750-24ts
switch 2 provision ws-c3750-24ts

switch 3 provision ws-c3750-24ts

on the switch to be added

1. 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.

2. Power off the switch that is to be added.

3. 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.

4. Connect the new switch to the stack with the StackWise ports.

5. Power on the newly added switch.

6. After the new switch comes up, issue the command show switch to verify stack membership.

is the above makes the config fine?but the Highlited in read confused me coz already the Priority in master in 1

[IAN WHITMORE]

You should be OK, but to be sure change the master switch priority to 2 or hishger.

Hi Lan

what about the below?do i need to add the coomand in red for the 3rd switch on master or no need for it,is this for configuration sync from the master to the new switch????

switch 1 provision ws-c3750-24ts
switch 2 provision ws-c3750-24ts

switch 3 provision ws-c3750-24ts

[IAN WHITMORE]

Yes, it would be a good idea to do so.

Ian
