IP(8)                               Linux                              IP(8)

NAME         top

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

SYNOPSIS         top

       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         top

       -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 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.

       -l, -loops <COUNT>
              Specify maximum number of loops the 'ip addr flush' logic will
              attempt before giving 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 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.

       -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.

IP - COMMAND SYNTAX         top

   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.
