The above output shows that the PC and the SecBlade cannot reach other, the SecBlade and Device A
can reach each other, and an error occurred on the connection between Device A and the PC. In this
case, use the debugging ip icmp command to enable ICMP debugging on the Device A and the
SecBlade to check whether the devices send or receive the specified ICMP packets, or use the display ip
routing-table command to display whether the PC and the SecBlade can reach each other.
