IP(8)                                         Linux                                         IP(8)



NAME
       ip - show / manipulate routing, devices, policy routing and tunnels

SYNOPSIS
       ip [ OPTIONS ] OBJECT { COMMAND | help }


       ip [ -force ] -batch filename


       OBJECT := { link | addr | addrlabel | route | rule | neigh | ntable | tunnel | tuntap |
               maddr | mroute | mrule | monitor | xfrm | netns | l2tp | tcp_metrics }


       OPTIONS := { -V[ersion] | -s[tatistics] | -r[esolve] | -f[amily] { inet | inet6 | ipx |
               dnet | link } | -o[neline] }



OPTIONS
       -V, -Version
              Print the version of the ip utility and exit.


       -b, -batch <FILENAME>
              Read commands from provided file or standard input and invoke them.  First failure
              will cause termination of ip.


       -force Don't terminate ip on errors in batch mode.  If there were any errors during execu‐
              tion of the commands, the application return code will be non zero.


       -s, -stats, -statistics
              Output more information.  If the option appears twice or more, the amount of infor‐
              mation increases.  As a rule, the information is statistics or some time values.


       -l, -loops <COUNT>
              Specify maximum number of loops the 'ip addr flush' logic will attempt before giv‐
              ing up.  The default is 10.  Zero (0) means loop until all addresses are removed.


       -f, -family <FAMILY>
              Specifies the protocol family to use. The protocol family identifier can be one of
              inet, inet6, bridge, ipx, dnet or link.  If this option is not present, the proto‐
              col family is guessed from other arguments.  If the rest of the command line does
              not give enough information to guess the family, ip falls back to the default one,
              usually inet or any.  link is a special family identifier meaning that no network‐
              ing protocol is involved.


       -4     shortcut for -family inet.


       -6     shortcut for -family inet6.


       -B     shortcut for -family bridge.


       -D     shortcut for -family decnet.


       -I     shortcut for -family ipx.


       -0     shortcut for -family link.


       -o, -oneline
              output each record on a single line, replacing line feeds with the '\' character.
              This is convenient when you want to count records with wc(1) or to grep(1) the out‐
              put.


       -r, -resolve
              use the system's name resolver to print DNS names instead of host addresses.


IP - COMMAND SYNTAX
   OBJECT
       address
              - protocol (IP or IPv6) address on a device.


       addrlabel
              - label configuration for protocol address selection.


       l2tp   - tunnel ethernet over IP (L2TPv3).


       link   - network device.


       maddress
              - multicast address.


       monitor
              - watch for netlink messages.


       mroute - multicast routing cache entry.


       mrule  - rule in multicast routing policy database.


       neighbour
              - manage ARP or NDISC cache entries.


       netns  - manage network namespaces.


       ntable - manage the neighbor cache's operation.


       route  - routing table entry.


       rule   - rule in routing policy database.


       tcp_metrics/tcpmetrics
              - manage TCP Metrics


       tunnel - tunnel over IP.


       tuntap - manage TUN/TAP devices.


       xfrm   - manage IPSec policies.


       The names of all objects may be written in full or abbreviated form, for exampe address
       can be abbreviated as addr or just a.


   COMMAND
       Specifies the action to perform on the object.  The set of possible actions depends on the
       object type.  As a rule, it is possible to add, delete and show (or list ) objects, but
       some objects do not allow all of these operations or have some additional commands.  The
       help command is available for all objects.  It prints out a list of available commands and
       argument syntax conventions.

       If no command is given, some default command is assumed.  Usually it is list or, if the
       objects of this class cannot be listed, help.


HISTORY
       ip was written by Alexey N. Kuznetsov and added in Linux 2.2.
