You can use the collaboration policy to manage the collaboration rules that belong to it.
Using ACFP
z
For VLANID-context devices, after ACFP is enabled, some VLAN IDs must not be used by any
other modules; otherwise, some data packets may be forwarded incorrectly.
z
In a GRE tunneling environment, an ACFP policy can be configured on a tunnel interface only.
z
ACFP does not support policy routing services or NetStream services.
z
The handling of the packets redirected by ACFP and the part of the QoS processing (FR-DE
matching, ATM-CLP matching, inbound interface matching, QoS local-id, local precedence, and
so on) are mutually exclusive. No QoS processing is performed on the packets returned after they
are redirected to the ACFP client.
z
On the destination interface, the packets redirected or mirrored by ACFP only support Layer 2 QoS
processing, including queuing, WRED (Weighted Random Early Detection), and so on; but not any
other service processing, such as non-Layer 2 QoS processing and non-QoS service processing.
z
With ACFP, a stream cannot be mirrored or redirected to multiple ACFP clients.
z
ACFP cannot process outbound packets.
z
For multi-core and software forwarding devices, ACFP does not support the handling of the
following types of packets: broadcasts, multicasts, MPLS packets, inbound packets, and IPv6
packets.
z
For multi-core and software forwarding devices, ACFP redirects and mirrors any IP datagram not
greater than 1,500 bytes (length of Layer 3 packet, excluding link layer header) but discards any IP
datagram greater than 1,500 bytes.
z
For software forwarding devices, if the contents of the rules matched by the packet on the inbound
interface or outbound interface exceed the quintuple information, the packet does not create fast
forwarding cache when being forwarded and therefore will not be fast forwarded.
