Can you stack two EtherSwitch modules in a chassis without the need to connect the Gigabit Ethernet ports?
A. No, there is no support to stack without a connection of the two Gigabit Ethernet interfaces. Connection of the two Gigabit Ethernet interfaces and use of the stacking-partner command eliminates conflicts in the VLAN databases between the two modules. If you install two modules without this connection, the result is duplications in the VLAN databases. There is no support for such duplications.
