Configure Local SPAN Session

Table 5-2 Configure the Local SPAN session

• ---

  When configuring the session source end and specifying the port enabled with the mirror as the aggregation group, the specified aggregation group should be already created. If the aggregation group is not created, the configuration fails. Similarly, when configuring the session destination end and specifying the forwarding port of the mirror packet as the aggregation group, the specified aggregation group also should be already created. If the aggregation group is not created, the configuration fails.
• One port cannot be the source port and destination port of one session at the same time.
• One port cannot exist in multiple sessions at the same time. The source of the port mirror session cannot be the same as the source of the flow mirror.
