A.By perfornubg a show ip interface to see the type and source of the attack based upon the access-listmatches
B.By performing a show interface to see the transmitted load "txload" and receive load "rxload" ；if the interface utilization is not maxed out ，there is no attack underway
C.By setting up an access-list to permit all ICMP，TCP，and UDP traffic with the log or log-input commands，then use the show access-list and show log commands to determine the type and sourceof attack

A.DPT/RPR uses a bi-directional ring consisting of two symmetric counter rotating fibre rings.
B.DPT/RPR is defined in the IEEE 802.17 standard and it uses Token Bucket system to avoid collisions on the fiber.
C.In DPT/RPR rings， data packets can be sent in one direction （downstream） and the corresponding control packets in the opposite direction （upstream），thus using both fibres concurrently to maximise bandwidth.
D.DPT/RPR can be deployed in the Core of the SP networks where point-to-point POS links are used tomake best use of the Bandwidth.
