Hi Community,
I have 2 WS-C3750G-24TS-1U in the stack. After turning off the Master switch and re-electing master for the second switch I have about 40 seconds downtime before Vlan-interfaces become up.
According this documentation I have to have only 3-5 seconds for L3-interfaces.
The newly elected stack master begins accepting Layer 2 traffic in less than 1 second and Layer 3 traffic between 3 to 5 seconds.
Could you suggest what the problem might be?

2 28 WS-C3750G-24TS-1U 12.2(55)SE12 C3750-IPSERVICESK9-M

WTF. Did you pull the power immediately after Switch 1 came online?
