VXLAN can't ping each other after apply traffic policy

Latest reply: Dec 29, 2018 12:18:27 592 13 11 2



Please help to check since we can’t ping the same subnet between VXLAN after applytraffic-policy, but other different subnet is fine.

 Below sample of config:


[~switch-COR01-acl4-advance-3024]dis this


aclnumber 3024

rule5 permit ip vpn-instance vrf_global destination

rule6 permit icmp vpn-instance vrf_global



bridge-domain 24

traffic-policy P3024 inbound                                      “we apply this one”


ask customer to explain the issue in details and feedback network topo diagnose information

customer request for remote troubleshooting and help

Root Cause

It is configuration issue and ACL deny the XVLAN underlay traffic


It is configuration issue and ACL deny the XVLAN underlay traffic

acl number 3024

 rule 9 deny ip vpn-instance vrf_global destination

acl 3024

If a message indicating that the service fails to be delivered because of insufficient resources is displayed on the switch when this function is configured, you are advised to configure MQC-based traffic statistics collection.

For the CE12800, traffic statistics collection on a Layer 2 sub-interface is mutually exclusive with BD traffic statistics collection and VLAN traffic statistics collection

The number of applied rules that contain "range" has reached or exceeded the maximum.

S7700 and S9700: The S series cards support 16 TCP or UDP port ranges and the E series cards support 32 TCP or UDP port ranges. When the number of ranges applied in the inbound direction exceeds the maximum, the preceding error is reported.
