Parameters
ipv6: Specifies an IPv6 ACL.
acl-number: Specifies an ACL by its number in the range of 3000 to 3999.
name acl-name: Specifies an ACL by its name, a case-insensitive string of 1 to 63 characters.
aggregation: Specifies the data protection mode as aggregation. The device does not support protecting
IPv6 data flows in aggregation mode.
per-host: Specifies the data protection mode as per-host.
Usage guidelines
An IKE-based IPsec policy supports the following data flow protection modes:
Standard mode—One IPsec tunnel protects one data flow. The data flow permitted by an ACL rule
is protected by one IPsec tunnel that is established solely for it. The standard mode is used if you do
not specify the aggregation or the per-host mode.
Aggregation mode—One IPsec tunnel protects all data flows permitted by all the rules of an ACL.
This mode is only used to communicate with old-version devices.
Per-host mode—One IPsec tunnel protects one host-to-host data flow. One host-to-host data flow is
identified by one ACL rule and protected by one IPsec tunnel established solely for it. This mode
consumes more system resources when multiple data flows exist between two subnets to be
protected.
A manual IPsec policy supports only the standard mode.
Examples
# Reference ACL 3001 for the IPsec policy policy1.
