Parameters
parameters: Specifies IPsec SAs that use the specified destination IP address, security protocol, and SPI.
dest-address: Destination address, in dotted decimal notation.
protocol: Security protocol, which can be keyword ah or esp, case insensitive.
spi: Security parameter index in the range 256 to 4294967295.
policy: Specifies IPsec SAs that use an IPsec policy.
policy-name: Name of the IPsec policy , a case-insensitive string of 1 to 15 characters, including letters and digits.
seq-number: Sequence number of the IPsec policy, in the range 1 to 65535. If no seq-number is specified, all the policies in the IPsec policy group named policy-name are specified.
remote: Specifies SAs to or from a remote address, in dotted decimal notation.
Description
Use the reset ipsec sa command to clear IPsec SAs.
Immediately after a manually set up SA is cleared, the system automatically sets up a new SA based on the parameters of the IPsec policy. After IKE negotiated SAs are cleared, the system sets up new SAs only when IKE negotiation is triggered by interesting packets.
IPsec SAs appear in pairs. If you specify the parameters keyword to clear an IPsec SA, the IPsec SA in the other direction is also automatically cleared.
If you do not specify any parameter, the command clears all IPsec SAs.
