If both source an IPSec Configuration Parameters ============================== -interface-type -^^^^^^^^^^^^^^ +enable IPsec acceleration +^^^^^^^^^^^^^^^^^^^^^^^^^ -When VPP is used for offloading IPsec, it creates a virtual interface of a specific type to connect to a peer. The type of the interface can be configured using the following command: +When VPP is used for offloading IPsec, it creates a virtual interface to connect to peers. The interface type is always 'ipsec', which is used for IPsec tunnels. -.. cfgcmd:: set vpp settings ipsec interface-type <interface-type> +.. cfgcmd:: set vpp settings ipsec-acceleration -The available interface types are: - -- ``ipsec``: This is the default interface type used for IPsec tunnels. -- ``ipip``: This interface type encapsulates IPsec traffic within IP-in-IP packets. - -Select the interface type based on peers settings. In most cases, you need to use the ``ipsec`` type. +Enabling this option allows VPP to handle IPsec traffic more efficiently by offloading processing from the kernel. netlink ^^^^^^^ VPP uses netlink to receive IPSec event messages from the kernel. Proper settings of the following parameters are crucial for ensuring that VPP can process all such messages: -.. cfgcmd:: set vpp settings ipsec netlink batch-delay-ms <milliseconds> +.. cfgcmd:: set vpp settings lcp netlink batch-delay-ms <milliseconds> This parameter specifies the delay in milliseconds between processing batch netlink messages. -.. cfgcmd:: set vpp settings ipsec netlink batch-size <number> +.. cfgcmd:: set vpp settings lcp netlink batch-size <number> This parameter specifies the maximum number of netlink messages to process in a single batch. -.. cfgcmd:: set vpp settings ipsec netlink rx-buffer-size <number> +.. cfgcmd:: set vpp settings lcp netlink rx-buffer-size <number> This parameter specifies the size of the receive buffer for netlink socket. If you expect to offload a lot of IPsec tunnels or get frequent and intensive rekeying, you may need to increase this value. +.. note:: + + IPsec uses the same netlink parameters as LCP, so tuning them affects both LCP and IPsec processing. + Potential Issues and Troubleshooting ==================================== |
