3750 stack master failure

G.I II
Level 1
Level 1

We have a stack of a 3750E with a 3750X, when we turn off the master, a disconnection occurs for around one minute while only one request timeout is seen when the slave is turned off. Is this normal?

Details: in other words, when the slave switch is elected as the new master all the port-channels and some physical ports become in 'down' state before reobtaining the up state again, this results in a one minute outage. The question is: is it normal to have a layer2 control traffic interruption when the master fails and re-election occurs and if yes, what is the normal downtime in seconds. the layer2 control information such as port-channels LACP protocol are not synchronised to all slave switches by the master?
