I picked a few arbitrary networking platforms: From http://www.juniper.net/techpubs/software/junos-es/junos-es93/junos-es-jseries-quick-start/basic-connection-and-configuration-with-the-cli.html: root# set interfaces ge-0/0/0 unit 0 family inet address 1.1.2.31/24 >From http://wiki.mikrotik.com/wiki/Manual:IP/Address : [admin@MikroTik] ip address> add address=10.10.10.1/24 interface=ether2 From http://stackoverflow.com/questions/11225681/interface-configuration-in-arista-eos : localhost(config-if-Eth1)# ip address 172.16.204.4/24 (Arista's configuration manual is a PDF, hence linking to a random stackoverflow description.) From http://dev-random.net/d-link-dgs-3324sr-management-ip-address-configuration/ : config ipif System ipaddress 192.168.2.2/24 Cisco does it differently, and I'm sure some others do too, but the $ip/prefixlen notation is pretty common in the networking world at least. -- Tollef Fog Heen UNIX is user friendly, it's just picky about who its friends are
