z
Destination port number operator: Its type can be equal to, not equal to, greater than, less than,
greater than and less than. The following ending destination port number is meaning only when
the type is greater than and less than. The destination port number of the packets matched by the
identifier must be greater than the starting destination port number and less than the ending
destination port number.

z
Pro: Protocol type, which can be GRE, ICMP, IGMP, OSPF, TCP, UDP, and IP.
z
IP precedence: Packet precedence, a number in the range of 0 to 7.
z
IP ToS: Type of Service (ToS) of IP
z
IP DSCP: Differentiated Services Code Point (DSCP) of IP
z
TCP flag: It indicates that some bits in the six flag bits (URG, ACK, PSH, RST, SYN, FIN) are
concerned.
z
IP fragment: It indicates whether the packet is an IP packet fragment.

You can use the collaboration policy to manage the collaboration rules that belong to it.
Using ACFP
z
In a GRE tunneling environment, an ACFP policy can be configured on a tunnel interface only.
z
QoS processing such as marking the QoS local ID and local priority for the packets is not
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
ACFP does not support the handling of the following types of packets: broadcasts, multicasts,
MPLS packets, inbound packets, and IPv6 packets.
z
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.
