Re-establishing SAs

An IKEv2 SA or IPsec SA is re-established after the SA is cleared. When the SA is cleared, any existing child SAs are also cleared and re-established.

  • Enter the clear ikev2 sa command to clear and re-establish an IKEv2 SA. The following example shows how to clear an IKEv2 SA (and any existing child SAs) by specifying the local IPv4 address for the SA.
    
    device# clear ikev2 sa local 10.1.1.1
    
  • Enter the clear ipec sa command to clear and re-establish an IPsec SA. The following example shows how to clear an IPsec SA by specifying the peer address for the SA.
    
    device# clear ipsec sa peer 10.2.2.2
