       ID     is specified by a source address, destination address, transform
              protocol XFRM-PROTO, and/or Security Parameter Index SPI.   (For
              IP  Payload  Compression, the Compression Parameter Index or CPI
              is used for SPI.)


       XFRM-PROTO
              specifies a transform  protocol:  IPsec  Encapsulating  Security
              Payload (esp), IPsec Authentication Header (ah), IP Payload Com-
              pression (comp), Mobile IPv6 Type 2 Routing Header (route2),  or
              Mobile IPv6 Home Address Option (hao).


       ALGO-LIST
              contains  one  or more algorithms to use. Each algorithm ALGO is
              specified by:

              o      the  algorithm  type:  encryption  (enc),  authentication
                     (auth or auth-trunc), authenticated encryption with asso-
                     ciated data (aead), or compression (comp)

              o      the algorithm name ALGO-NAME (see below)

              o      (for all except comp) the  keying  material  ALGO-KEYMAT,
                     which  may  include both a key and a salt or nonce value;
                     refer to the corresponding RFC

              o      (for auth-trunc only) the truncation  length  ALGO-TRUNC-
                     LEN in bits

              o      (for  aead  only)  the Integrity Check Value length ALGO-
                     ICV-LEN in bits

              Encryption  algorithms   include   ecb(cipher_null),   cbc(des),
              cbc(des3_ede),      cbc(cast5),     cbc(blowfish),     cbc(aes),
              cbc(serpent),       cbc(camellia),       cbc(twofish),       and
              rfc3686(ctr(aes)).

              Authentication   algorithms   include   digest_null,  hmac(md5),
              hmac(sha1),    hmac(sha256),     hmac(sha384),     hmac(sha512),
              hmac(rmd610), and xcbc(aes).

              Authenticated  encryption with associated data (AEAD) algorithms

       FLAG-LIST
              contains one or more of the following optional flags: noecn, de-
              cap-dscp, nopmtudisc, wildrecv, icmp, af-unspec, or align4.


       SELECTOR
              selects the traffic that will be controlled by the policy, based
              on  the source address, the destination address, the network de-
              vice, and/or UPSPEC.


       UPSPEC selects traffic by protocol. For the tcp,  udp,  sctp,  or  dccp
              protocols,  the  source  and  destination port can optionally be
              specified.  For the icmp, ipv6-icmp, or  mobility-header  proto-
              cols,  the  type  and  code numbers can optionally be specified.
              For the gre protocol, the key can optionally be specified  as  a
              dotted-quad  or number.  Other protocols can be selected by name
              or number PROTO.


       LIMIT-LIST
              sets limits in seconds, bytes, or numbers of packets.


       ENCAP  encapsulates packets with protocol espinudp or  espinudp-nonike,
              using  source  port SPORT, destination port DPORT , and original
              address OADDR.


              ip xfrm policy add         add a new policy
              ip xfrm policy update      update an existing policy
              ip xfrm policy delete      delete an existing policy
              ip xfrm policy get         get an existing policy
              ip xfrm policy deleteall   delete all existing xfrm policies
              ip xfrm policy list        print out the list of xfrm policies
              ip xfrm policy flush       flush policies
              ip xfrm policy count       count existing policies


       SELECTOR
              selects the traffic that will be controlled by the policy, based
              on  the source address, the destination address, the network de-
              vice, and/or UPSPEC.


       UPSPEC selects traffic by protocol. For the tcp,  udp,  sctp,  or  dccp
              protocols,  the  source  and  destination port can optionally be
              specified.  For the icmp, ipv6-icmp, or  mobility-header  proto-
              cols,  the  type  and  code numbers can optionally be specified.
              For the gre protocol, the key can optionally be specified  as  a
              dotted-quad  or number.  Other protocols can be selected by name
              or number PROTO.


       PRIORITY
              is a number that defaults to zero.


       FLAG-LIST
              contains one or both of the following optional flags:  local  or
              icmp.


       LIMIT-LIST
              sets limits in seconds, bytes, or numbers of packets.


       TMPL-LIST
              is  a template list specified using ID, MODE, REQID, and/or LEV-
              EL.


       ID     is specified by a source address, destination address, transform
              protocol  XFRM-PROTO, and/or Security Parameter Index SPI.  (For
              IP Payload Compression, the Compression Parameter Index  or  CPI
              is used for SPI.)


       XFRM-PROTO
              specifies  a  transform  protocol:  IPsec Encapsulating Security
              Payload (esp), IPsec Authentication Header (ah), IP Payload Com-
              pression  (comp), Mobile IPv6 Type 2 Routing Header (route2), or
              Mobile IPv6 Home Address Option (hao).


       MODE   specifies a mode of operation for the transform protocol.  IPsec
              and IP Payload Compression modes are transport, tunnel, and (for
              IPsec ESP only) Bound End-to-End  Tunnel  (beet).   Mobile  IPv6
              modes  are route optimization (ro) and inbound trigger (in_trig-
              ger).


       LEVEL  can be required (default) or use.

              The xfrm objects to monitor can be optionally specified.
