Create an IPsec Policy

Use the following procedure to configure an IPsec policy for an IPv4 or an IPv6 interface. An IPsec policy defines the level of security for different types of traffic.

Note

Note

  • You can only configure the IPsec policies for IPv4 addresses for UDP, TCP, and ICMPv4 protocols. You can continue to configure IPsec policies for IPv6 addresses for ICMPv6, OSPFv3, TCP, and UDP.

  • If you downgrade your software, the current IPsec configurations are no longer supported. You must boot with the factory default settings for IPsec, and then reconfigure the IPsec features.

About this task

You cannot delete or modify a policy if the policy links to a security association, or if the policy links to a port or VLAN interface. If you need to modify a policy you must first unlink the policy from the security association, and the port or VLAN interface.

Procedure

  1. In the navigation pane, expand Configuration > Security > Control Path.
  2. Select IPSec.
  3. Select the Policy tab.
  4. Select Insert.
  5. In the Name field, type a policy name.
  6. Complete the remaining optional configuration to customize the policy.
  7. Select Insert.
