we removed a switch 3750 from its stack, after that, the switch boots well like a standalone switch, but it gets soo slowly for example when i want to see its configuration through the console port (sh run), i review the sh switch, and i am still seeing that these switch are using the same id member that it used when it was in the stack, how can solve this? why the switch takes the number 2, and not the one? if i see the ports, the numbers begin by 2/0/1, and not by 1/0/0, could this problem cause the slow of the switch? this switch was the switch number 2 when it was in the stack. i cleared its configuration, and the i restarted, but the same.
