1) I am able to create VLAN on Juniper QFX5100 but when I am assigning interface to that VLAN it is showing an error "family ethernet-switching and other families are mutually exclusive"
Command used is
set vlans Customer1 vlan-id 11
set interfaces ge-0/0/0 unit 0 family ethernet-switching vlan members Customer1
On this interface I have already configured IP address
2) But when I am creating vlans on some other port with nothing configured on it, I am able to create the vlan
Command used is
set vlans Customer1 vland-id 11
Set interfaces ge-0/0/20.0 family ethernet-switching vlan members Customer1
This interface does not have any IP address configured on it.
And 1 more thing I would like to add is in 2nd query in commands if I am not adding .0 to the interface (i.e. ge-0/0/20.0) it will not showing me option of family after interface ge-0/0/20.0
Please help me to resolve this issue as i am just new to Juniper.
