DESCRIPTION
xfrm is an IP framework for transforming packets (such as encrypting
their payloads). This framework is used to implement the IPsec protocol
suite (with the
state object operating on the Security Association Database, and the
policy object operating on the Security Policy Database). It is also used for
the IP Payload Compression Protocol and features of Mobile IPv6.

ip xfrm state add add new state into xfrm |
ip xfrm state update update existing state in xfrm |
ip xfrm state allocspi allocate an SPI value |
ip xfrm state delete delete existing state in xfrm |
ip xfrm state get get existing state in xfrm |
ip xfrm state deleteall delete all existing state in xfrm |
ip xfrm state list print out the list of existing state in xfrm |
ip xfrm state flush flush all state in xfrm |
ip xfrm state count count all existing state in xfrm |
|
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 Compression (" 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:
\[bu]
the algorithm type:
"encryption (" enc ")," "authentication (" auth " or " auth-trunc ")," "authenticated encryption with associated data (" aead "), or" "compression (" comp ")" \[bu]
the algorithm name
ALGO-NAME (see below)
\[bu]
"(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
\[bu]
"(for " auth-trunc " only)" the truncation length
ALGO-TRUNC-LEN in bits
\[bu]
"(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)) "."

Authenticated encryption with associated data (AEAD) algorithms include
rfc4106(gcm(aes)) ", " rfc4309(ccm(aes)) ", and " rfc4543(gcm(aes)) "."
Compression algorithms include
deflate ", " lzs ", and " lzjh "."
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_trigger ")."
FLAG-LIST contains one or more of the following optional flags:
noecn ", " decap-dscp ", " nopmtudisc ", " wildrecv ", " icmp ", " af-unspec ", " align4 ", or " esn "."
SELECTOR selects the traffic that will be controlled by the policy, based on the source
address, the destination address, the network device, 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 protocols, 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 |
|
SELECTOR selects the traffic that will be controlled by the policy, based on the source
address, the destination address, the network device, 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 protocols, 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 "."
DIR selects the policy direction as
in ", " out ", or " fwd "."
CTX sets the security context.
PTYPE can be
main " (default) or " sub "."
ACTION can be
allow " (default) or " block "."
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 " LEVEL ". "
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 Compression (" comp ")," "Mobile IPv6 Type 2 Routing Header (" route2 "), or" "Mobile IPv6 Home Address Option (" hao ")."

"(" beet ")." Mobile IPv6 modes are route optimization

LEVEL can be
required " (default) or " use "."
|
ip xfrm policy count count existing policies |
|
Use one or more -s options to display more details, including policy hash table
information.
|
ip xfrm policy set configure the policy hash table |
|
Security policies whose address prefix lengths are greater than or equal
policy hash table thresholds are hashed. Others are stored in the
policy_inexact chained list.
LBITS specifies the minimum local address prefix length of policies that are
stored in the Security Policy Database hash table.
RBITS specifies the minimum remote address prefix length of policies that are
stored in the Security Policy Database hash table.
|
ip xfrm monitor state monitoring for xfrm objects |
|
The xfrm objects to monitor can be optionally specified.
If the
all-nsid option is set, the program listens to all network namespaces that have a
nsid assigned into the network namespace were the program is running.
A prefix is displayed to show the network namespace where the message
originates. Example:
[nsid 1]Flushed state proto 0
