Not just the 'c' in create:

[root@pom] # ifconfig vlan30
vlan30: no such interface
[root@pom] # ifconfig vlan30 fiets
ifconfig: fiets: bad value
[root@pom] # ifconfig vlan30
vlan30: flags=8002<BROADCAST,MULTICAST> mtu 1500
        lladdr 00:00:00:00:00:00
        index 5 priority 0 llprio 3
        vnetid: none
        parent: none
        groups: vlan
        status: no carrier

You can change the error message you get by

        echo 10.0.0.1 fiets >> /etc/hosts

Or, in your case, '10.0.0.1 changelist' etc.
