Changing priority value of existing stackmaster..Please help

Hi,

Currently i have the following settings :

Switch#  Role    Mac Address     Priority    Version     State

----------------------------------------------------------

1       Member  d0d0.fd60.4580     1         1               Ready              

*2       Master   d0d0.fd61.5b80      2         1               Ready

now i need to add one omre (new) 3750 to the stack. The IOS versions and all are the same. I assume i have to first change the priroty value of the master to 15. But what would happen after this. Actually production systems are connected to the Master. When the priority value is changed would it reboot the master switch.???

Please advice anyone.

Hi,

If the requirement is just to add one more stack member, then no need to change the priority

Stack master and switch priority conflicts are resolved in this order:

1. The switch that is already master remains unchanged.

2. The switch (or stack) whose master has a higher user-configured priority.

3. The switch (or stack) that is not using the default configuration.

4. The switch (or stack) with the more recent license or image version.

5. The switch (or stack) with the higher hardware priority or hardware version.

6. The stack with the most members (if two stacks are being connected).

7. The switch with the lowest MAC addresses.

renumbering will not cause any disturbance and you can do this as an additional task (for better housekeeping etc)
