Restrictions and Cautions
Limitation 1
【PING】Before transmission, big packets are fragmented by MTU (Maximum Transmission Unit),
and SW8800 will give no response until all the fragments reach. To protect the CPU against shocks,
the rate of traffic sent to the CPU for processing is restricted. For this reason, when a fragment of the
packet is discarded by the CPU, the big packet used to PING may be dropped.
Limitation 2
【 Link Aggregation 】 Upon trans-board link-aggregation, the board with members of the link-
aggregation group cannot be pulled out or inserted back. If the board is pulled out, there will be flow
interruption for a short period of time. And when the board is inserted back, there will be much more
serious flow interruption during the restoration of configuration.
Limitation 3
【Link Aggregation】 ACL rules cannot be repeatedly deleted and applied on a port , which is the
member of a trans-board link-aggregation group. Otherwise, ACL rules may fail to be applied on the
port, and the port will exit the link-aggregation group.
