Which of the following are possible criteria for classifying packets at the network port ingress on the Alcatel-Lucent 7750 SR? (Choose three)
When classifying packets at the network port ingress on the Alcatel-Lucent 7750 SR, it is common to use criteria such as the EXP bits in the MPLS header, the packet's DSCP bits, and the dot1p bits in the frame header. These elements are typically used because they provide essential information for packet classification, which can be used for quality of service (QoS) and traffic management. The source and destination IP addresses, while useful for routing decisions, are not typically used as classification criteria at the port ingress in this context. The ID of an SDP that is transporting the packet is also not a standard criterion for packet classification at network port ingress.
a,c d is wrong
Please elaborate.
multi field is not available in network port ingress. so A C D is correct.
The Alcatel-Lucent 7750 Service Router (SR) is a service routing platform designed for the delivery of advanced residential, enterprise, and mobile services. When classifying packets at the network port ingress on the Alcatel-Lucent 7750 SR, the following criteria can be considered: B. The packet's source and destination IP addresses. C. The packet's DSCP (Differentiated Services Code Point) bits. D. The dot1p bits in the frame header. Therefore, the three possible criteria for classifying packets at the network port ingress on the Alcatel-Lucent 7750 SR are B, C, and D. by chatGpt
When traffic arrives at the network interface of a Nokia 7750 SR, it is mapped to a forwarding class in the following order of matching criteria: 1. The default settings configured in the network policy will be used by default. 2. If there is a dot1p match, the configured action will be applied. This is only possible if the network interface’s encapsulation type is dot1q. 3. Finally, the EXP bits are inspected when MPLS labels are present (VPN tunneled services). Otherwise, the DSCP field is inspected when GRE-tunneled packets or regular IP packets are received. If there is a match, the specified action will be applied.
