4 stack member switch , removed one switch - is removed switch retain all configuration

[lerner cisco]

All,

I got  4  3750 series switch stack member  , plan was remove one switch  that is 2nd switch in stack member which was  stack master . the uplink trunks configured on the first switch  member that is Gi 1/0/49 & Gi 1/0/50 .

Once 2 nd stack member switch removed , and connected SFP on the port Gi 1/0/49 - trunk was not coming up , would like to understand , once the  2nd stack member switch removed from the stack  , it will become a master and retain all  configuration including ports  that is Gi 1/0/1-52 to Gi 4/0/1-52

before removing the switch  switch provision command exist  , my thinking the removed switch also have all the provision commands on the switch and with all port configuration  Gi 1/0/1-52 to Gi 4/0/1 -52 ??   please suggest

switch 1 provision ws-c3750e-48pd
switch 2 provision ws-c3750e-48pd
switch 3 provision ws-c3750e-48pd
switch 4 provision ws-c3750e-48pd

Regards

Lerner

Every stack member keeps a copy of the stack config.  I.e. it doesn't matter which switch is "master".

When you removed switch #2, and booted alone, yes it would be the stack master, but it still would be switch #2 so it would not have switch #1 ports, including the uplinks.

If you want the removed switch #2 to become switch #1, when running alone, it might work if you renumber the switch member to #1.  (This also, I believe, requires switches number 1 and 2 to be the same model, and from what you've posted, that appears to be true.)
