VLAN Creation on Juniper QFX5100

Question

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.

Answer 1

 family ethernet-switching and other families are mutually exclusive

You're using too many parameters under the family stanza. This extra parameter is family inet based on this:

”On this interface I have already configured IP address.”

Run user@qfx5100# delete interfaces ge-0/0/0.0 family inet. Optionally, you could delete all of ge-0/0/0.0 with user@qfx5100# delete interfaces ge-0/0/0.0 and then put your configurations back in.

When running show interfaces and show vlans, you should see this:

interfaces {
    ge-0/0/0 {
        unit 0 {
            family ethernet-switching {
                vlan {
                    members Customer1;
                }
            }
        }
    }
    ge-0/0/20 {
        unit 0 {
            family ethernet-switching {
                vlan {
                    members Customer1;
                }
            }
        }
    }    
}
vlans {
    Customer1 {
        vland-id 11;
    }
}
