usage:  ifconfig [-aS] [INTERFACE [ACTION...]]
Display or configure network interface.
With no arguments, display active interfaces. First argument is interface
to operate on, one argument by itself displays that interface.
-a      All interfaces displayed, not just active ones
-S      Short view, one line per interface
Standard ACTIONs to perform on an INTERFACE:
ADDR[/MASK]        - set IPv4 address (1.2.3.4/5) and activate interface
add|del ADDR[/LEN] - add/remove IPv6 address (1111::8888/128)
up|down            - activate or deactivate interface
Advanced ACTIONs (default values usually suffice):
default          - remove IPv4 address
netmask ADDR     - set IPv4 netmask via 255.255.255.0 instead of /24
txqueuelen LEN   - number of buffered packets before output blocks
mtu LEN          - size of outgoing packets (Maximum Transmission Unit)
broadcast ADDR   - Set broadcast address
pointopoint ADDR - PPP and PPPOE use this instead of "route add default gw"
hw TYPE ADDR     - set hardware (mac) address (type = ether|infiniband)
Flags you can set on an interface (or -remove by prefixing with -):
arp       - don't use Address Resolution Protocol to map LAN routes
promisc   - don't discard packets that aren't to this LAN hardware address
multicast - force interface into multicast mode if the driver doesn't
allmulti  - promisc for multicast packets[ ToyBox ]     [ ManLinux ]
