Hi, I confirm that it is possible to configure 4 x 10 Gb stack connections. The output shown above was caused by a failure of the switch elected as master. To solve this problem I had to migrate all the infrastructure on a new stack with updated firmware. Thanks
Hi guys, I have to configure a new stack with 2 4032f using only 10Gb interface without any external module. I saw in the manual the following commands to create the stack:   console#configconsole(config)#stackconsole(config-stack)#stack-port fortygigabitethernet 1/1/1 stackconsole(config-stack)#stack-port fortygigabitethernet 1/1/2 stack   Do you know if is possible apply this configuration on 4 * 10Gb interfaces ? E.G. console#configconsole(config)#stackconsole(config-stack)#stack-port Tengigabitethernet 1/0/21 stackconsole(config-stack)#stack-port Tengigabitethernet 1/0/22 stack console(config-stack)#stack-port Tengigabitethernet 1/0/23 stackconsole(config-stack)#stack-port Tengigabitethernet 1/0/24 stack If so, Will these interface be displayed in the show running after creating the stack?   Thank you   P.s. why is it a 4032 if it has only 24 interfaces?
