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 |
Authentication algorithms include digest_null, hmac(md5), hmac(sha1), hmac(sha256), hmac(sha384), hmac(sha512), hmac(rmd160), and xcbc(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.
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 |
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.
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
