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 | address | addrlabel | route | rule | neigh | ntable
               | tunnel | tuntap | maddress | mroute | mrule | monitor | xfrm
               | netns | l2tp | tcp_metrics }

       OPTIONS := { -V[ersion] | -h[uman-readable] | -s[tatistics] |
               -r[esolve] | -f[amily] { inet | inet6 | ipx | dnet | link } |
               -o[neline] | -n[etns] name | -a[ll] | -c[olor] }

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

       -h, -human, -human-readable
              output statistics with human readable values followed by suffix.

       -b, -batch 
              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 execution 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 information increases.  As a rule, the information
              is statistics or some time values.

       -d, -details
              Output more detailed information.

       -l, -loops 
              Specify maximum number of loops the 'ip address flush' logic
              will attempt before giving up. The default is 10.  Zero (0)
              means loop until all addresses are removed.

       -f, -family 
              Specifies the protocol family to use. The protocol family iden-
              tifier can be one of inet, inet6, bridge, ipx, dnet, mpls or
              link.  If this option is not present, the protocol 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 networking 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.

       -M     shortcut for -family mpls.

       -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 output.

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

       -n, -netns 
              switches ip to the specified network namespace NETNS.  Actually
              it just simplifies executing of:

              ip netns exec NETNS ip [ OPTIONS ] OBJECT { COMMAND | help }

              to

              ip -n[etns] NETNS [ OPTIONS ] OBJECT { COMMAND | help }

       -a, -all
              executes specified command over all objects, it depends if com-
              mand supports this option.

       -c, -color
              Use color output.

       -t, -timestamp
              display current time when using monitor option.

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 example 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 com-
       mands 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.

EXIT STATUS
       Exit status is 0 if command was successful, and 1 if there is a syntax
       error.  If an error was reported by the kernel exit status is 2.

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