HP Firewall Series - HP AF5000-CMW520-R3206P22 Release Notes
3
RMON statistics restriction
The interfaces on the MPUs and 12-GE interface modules do not support the RMON statistics function. This is
a hardware restriction.
ICMP fragement sending restriction
When the length of an ICMP echo request used for a ping operation is greater than 35000 bytes, the packet will
be fragmented due to the restriction of the interface MTU. The longer the ping packet, the more the fragments.
However, the F5000-A5 does not support QoS queuing, and packets that cannot to be sent out of an interface
are directly dropped. Because the number of credits sent by the RMI fixed port is limited, fragments might not
be able to be sent out successfully when a large number of fragments need to be sent and the burst rate is
greater than the rate of the interface. As a result, some fragments cannot arrive at the intended receiver and the
intended receiver cannot assemble the ICMP packets.
10-GE interface module cannot provide erroneous packet statistics
10-GE interface module cannot provide erroneous packet statistics because its MAC chip does not support
erroneous packet statistics.
MTU restriction on Layer 3 aggregation interfaces
When the MTU of a Layer 3 aggregation interface is greater than 1500, (for example, 1560), fragments cannot
be sent out successfully because the length of the Layer 2 frame is 1500 at most.
Make sure the MTU of a Layer 3 aggregation interface is not greater than 1500.
