Sorry to bother you with this, but I hope someone can quickly give me an answer to that "easy" question:
I have a stack of two 3750, configured by some technician, and now need to maintain them.
In the config, I can only find these lines regarding a stack:
switch 1 provision ws-c3750g-48ps
switch 2 provision ws-c3750g-48ps
...
interface Vlan1
ip address xx.xx.xx.xx 255.255.252.0
Show switch gives:
Switch/Stack Mac Address : 001b.0dcd.d680
H/W Current
Switch# Role Mac Address Priority Version State
------------------------------------------------------
1 Member 001b.0dcd.d980 1 0 Ready
*2 Master 001b.0dcd.d680 1 0 Ready
Now the questions:
- I have no experience with switch stacks, so I've read the chapters in the manual.
To me it looks that master election is based on MAC address, am I wrong?
Could it be that after a reboot or an IOS update, master and server roles get swapped for some reason?
- What happens if I replace any of the stack members with an unconfigured, freshly unpacked spare switch?
I need master and member roles to be kept, is that provided with the configuration that I have?
