How to view information such as interface status and packet loss
You can run the display this interface command in the interface view to check the physical status, protocol status, traffic statistics, and the number of lost packets on an interface.

How is the source IP address of ping packets specified
The -a parameter specifies the source IP address of ping packets. If -a is not specified, the system searches for the outbound interface mapping the destination IP address in the routing table and uses the outbound interface's IP address as the source IP address of ping packets. If there are equal-cost routes to the destination IP address, the system performs the hash algorithm based on the destination IP address, protocol number, ICMP type, and ICMP mode and selects the outbound interface's IP address as the source IP address of ping packets.

How to check ping packet loss on S series switches
For S series switches (except the S1700), you can run the ping command to check ping packet loss directly. For example: [HUAWEI] ping -c 100 192.168.2.21 PING 192.168.2.21: 56 data bytes, press CTRL_C to break Reply from 192.168.2.21: bytes=56 Sequence=1 ttl=124 time=1 ms ... --- 192.168.2.21 ping statistics --- 100 packet(s) transmitted //Total number of sent packets 91 packet(s) received //Total number of received packets 9.00% packet loss //Packet loss ratio round-trip min/avg/max = 1/1/19 ms You can also perform the following steps to configure traffic statistics collection to check ping packet loss: Configure traffic statistics collection for packets received by a switch. 1. Configure an ACL rule. [HUAWEI] acl number 3000 [HUAWEI-acl-adv-3000] rule permit icmp source 192.168.2.21 0 destination 192.168.2.20 0 [HUAWEI-acl-adv-3000] quit 2. Configure a traffic classifier. [HUAWEI] traffic classifier 3000 [HUAWEI-classifier-3000] if-match acl 3000 [HUAWEI-classifier-3000] quit3. Configure a traffic behavior. [HUAWEI] traffic behavior 3000 [HUAWEI-behavior-3000] statistic enable [HUAWEI-behavior-3000] quit 4. Configure a traffic policy. [HUAWEI] traffic policy 3000 [HUAWEI-trafficpolicy-3000] classifier 3000 behavior 3000 [HUAWEI-trafficpolicy-3000] quit 5. Apply the traffic policy to an interface. [HUAWEI] interface gigabitethernet 0/0/2 [HUAWEI-GigabitEthernet0/0/2] traffic-policy 3000 inbound [HUAWEI-GigabitEthernet0/0/2] quit 6. Check traffic statistics of packets received by the switch. [HUAWEI] display traffic policy statistics interface gigabitethernet 0/0/2 inbound verbose rule-base //The output is omitted.
