ike (Security)

Syntax

Hierarchy Level

Description

Define Internet Key Exchange (IKE) configuration. IKE is a key management protocol that creates dynamic SAs; it negotiates SAs for IPsec. An IKE configuration defines the algorithms and keys used to establish a secure connection with a peer security gateway.

Options

respond-bad-spi max-responses—(Optional) Number of times to respond to invalid SPI values per gateway. Enable response to invalid IPsec Security Parameter Index (SPI) values. If the security associations (SAs) between two peers of an IPsec VPN become unsynchronized, the device resets the state of a peer so that the two peers are synchronized.

  • Range: 1 through 30

  • Default: 5

traceoptions—Configure IKE tracing options to aid in troubleshooting the IKE issues. This helps troubleshoot one or multiple tunnels negotiation by standard tracefile configuration. IKE tracing allows the user to view the detailed packet exchange and the negotiation information in Phase 1 and Phase 2. IKE tracing is not enabled by default. By default , all IKE or IPsec negotiations are logged into /var/log/kmd. But user can also specify customized file name while configuring the IKE traceoptions.

The remaining statements are explained separately. See CLI Explorer.
