crypto ipsec ike

crypto ipsec ike {clear sa [peer {any | <ipv4v6-address>} local <ip-address>] | restart}

Syntax Description

clear

Clears IKE (ISAKMP) peering state

sa

Clears IKE generated ISAKMP and IPSec security associations (remote peers are affected)

peer

Clears security associations for the specified IKE peer (remote peers are affected).

  • all – clears security associations for all IKE peerings with a specific local address (remote peers are affected)

  • IPv4 or IPv6 address – clears security associations for specific IKE peering with a specific local address (remote peers are affected)

local

Clear security associations for the specified/all IKE peering (remote peer is affected)

restart

Restarts the IKE (ISAKMP) daemon (clears all IKE state, peers may be affected)

Syntax Description

enable

Enables IPSec peering

ike

Configures IPSec peering using IKE ISAKMP to manage SA keys.

  • auth – configures the authentication algorithm for IPSec peering

  • dh-group – configures the phase1 Diffie-Hellman group proposed for secure IKE key exchange

  • disable – configures this IPSec peering administratively disabled

  • encrypt – configures the encryption algorithm for IPSec peering

  • exchange-mode – configures the IKE key exchange mode to propose for peering

  • lifetime – configures the SA lifetime to propose for this IPSec peering

  • local-identity – configures the ISAKMP payload identification value to send as local endpoint's identity

  • mode – configures the peering mode for this IPSec peering

  • peer-identity – configures the identification value to match against the peer's ISAKMP payload identification

  • pfs-group – configures the phase2 PFS (Perfect Forwarding Secrecy) group to propose for Diffie-Hellman exchange for this IPSec peering

  • preshared-key – configures the IKE pre-shared key for the IPSec peering

  • prompt-preshared-key – prompts for the pre-shared key, rather than entering it on the command line

  • transform-set – configures transform proposal parameters

keying

Configures key management for this IPSec peering:

  • auth – configures the authentication algorithm for this IPSec peering

  • disable – configures this IPSec peering administratively disabled

  • encrypt – configures the encryption algorithm for this IPSec peering

  • local-spi – configures the local SPI for this manual IPSec peering

  • mode – configures the peering mode for this IPSec peering

crypto certificate ca-list

crypto certificate ca-list [default-ca-list {name {<CA list name> | system-self-signed}}]

no crypto certificate ca-list [default-ca-list {name {<cert-name> | system-self-signed}}]

Adds the specified CA certificate to the default CA certificate list.

The no form of the command removes the certificate from the default CA certificate list.

Related Commands

Notes

  • Two certificates with the same subject and issuer fields cannot both be placed onto the CA list

  • The no form of the command does not delete the certificate from the certificate database

  • Unless specified otherwise, applications that use CA certificates will still consult the well-known certificate bundle before looking at the default-ca-list

crypto certificate default-cert

crypto certificate default-cert [{name {<cert-name> | system-self-signed}}]

no crypto certificate default-cert [{name {<cert-name> | system-self-signed}

Designates the named certificate as the global default certificate role for authentication of this system to clients.

The no form of the command reverts the default-cert name to "system-self-signed" (the "cert-name" value is optional and ignored).

Syntax Description

cert-name

Notes

  • A certificate must already be defined before it can be configured in the default-cert role

  • If the named default-cert is deleted from the database, the default-cert automatically becomes reconfigured to the factory default, the "system-self-signed" certificate

crypto certificate generation

crypto certificate generation {default {country-code | days-valid | email-addr | key-size-bits | locality | org-unit | organization | state-or-prov}

Configures default values for certificate generation.

Syntax Description

country-code

Configures the default certificate value for country code with a two-alphanumeric-character code or – for none

days-valid

Configures the default certificate valid days. Default: 365 days.

email-addr

Configures the default certificate value for email address

key-size-bits

Configures the default certificate value for private key size. (Private key length in bits – at least 1024, but 2048 is strongly recommended.)

locality

Configures the default certificate value for locality

org-unit

Configures the default certificate value for organizational unit

organization

Configures the default certificate value for the organization name

state-or-prov

Configures the default certificate value for state or province

  • days-valid – specifies the number of days the certificate is valid

  • email-addr – specifies the email address

  • key-size-bits – specifies the size of the private key in bits (private key length in bits – at least 1024 but 2048 is strongly recommended)

  • locality – specifies the locality name

  • org-unit – specifies the organizational unit name

  • organization – specifies the organization name

  • serial-num – specifies the serial number for the certificate (a lower-case hexadecimal serial number prefixed with “0x”)
