Hi
Could you please help make a detail issue destription about this issue ? include the network topology
and also the 127.0.0.1 is same with 127.0.0.02 because both are internal loopback port, there is no difference
Also we can configuration the traffic statistics to check whrer the packets loss. for example:
acl 3001
rule permit icmp source 192.168.1.10 0.0.0.0 destination 192.168.2.10 0.0.0.0 // source address and destination address
rule permit icmp source 192.168.2.10 0.0.0.0 destination 192.168.1.10 0.0.0.0
traffic classifier ping // Create the classifier
if-match acl 3001 // Match the acl
traffic behavior ping // Create the behavior
statistic enable
traffic policy ping
classifier ping behavior ping
interface g 0/0/10 // need add the traffic policy to the traffic path both inbound and outbound
traffic-policy ping inbound
traffic-policy ping outbound
int g 0/0/20 // both traffic path port need add the policy
traffic-policy ping inbound
traffic-policy ping outbound
<huawei>reset traffic policy statistics interface GigabitEthernet 0/0/10 inbound
<huawei>reset traffic policy statistics interface GigabitEthernet 0/0/10 outbound
<huawei>reset traffic policy statistics interface GigabitEthernet 0/0/20 inbound
<huawei>reset traffic policy statistics interface GigabitEthernet 0/0/20 outbound
Then please keep pinging and then we can found where the packets not pass.
