Enabling Ipv4 Acl Acceleration - HP A6600 Configuration Manual

Copying an IPv4 ACL
To do...
1. Enter system view.
2. Copy an existing IPv4 ACL to create a
new IPv4 ACL.
Copying an IPv6 ACL
To do...
1. Enter system view.
2. Copy an existing IPv6 ACL to generate a
new one of the same category.

Enabling IPv4 ACL acceleration

ACL acceleration speeds up ACL lookup. The acceleration effect increases with the number of ACL rules. ACL
acceleration uses memory. To achieve the best trade-off between memory and ACL processing performance,
HP recommends enabling ACL acceleration for large ACLs.
For example, when you use a large ACL for a session-based service, such as NAT or ASPF, enable ACL
acceleration to avoid session timeouts caused by ACL processing delays.
Enable ACL acceleration in an ACL after you have finished editing ACL rules. ACL acceleration always uses
ACL criteria that have been set before it is enabled for rule matching. It does not synchronize with any
subsequent match criterion changes.
ACL acceleration is not available for ACLs that contain a non-contiguous wildcard mask.

After you modify an IPv4 ACL with ACL acceleration enabled, disable and re-enable ACL acceleration

to ensure correct rule matching.
To enable ACL acceleration for an IPv4 ACL:
To do...
1. Enter system view.
2. Enable ACL acceleration for an
IPv4 ACL.
