ACI dropped packets confusion

JPC113
Level 1
Level 1

Hi,

I am new to ACI and was recently looking at the operations tab and ran a query and I am not sure that I understand the results. 

I have a host that sits outside of ACI (10.131.161.38) and a host inside of ACI (192.168.209.148) I can happily ping from outside of the ACI environment to the host, however, the output from the query suggests that packets are being dropped.

If I login to the boarder leaves I have a full ospf adjacency on both switches 

 

LEAF_102# show ip ospf neighbors vrf PRODUCTION:PRODUCTION_VRF

​‌

OSPF Process ID default VRF PRODUCTION:PRODUCTION_VRF
Total number of neighbors: 1
Neighbor ID Pri State Up Time Address Interface
192.168.128.254 1 FULL/DR 4w3d 192.168.10.69 Eth1/2
 
LEAF_103# show ip ospf neighbors vrf PRODUCTION:PRODUCTION_VRF
OSPF Process ID default VRF PRODUCTION:PRODUCTION_VRF
Total number of neighbors: 1
Neighbor ID Pri State Up Time Address Interface
192.168.128.254 1 FULL/DR 4w3d 192.168.10.71 Eth1/2
 
and a route table 

LEAF_103# show ip route summary vrf PRODUCTION:PRODUCTION_VRF
IP Route Table for VRF "PRODUCTION:PRODUCTION_VRF"
Total number of routes: 872
Total number of paths: 879

Best paths per protocol: Backup paths per protocol:
ospf-default : 860 ospf-default : 6
bgp-65535 : 1
static : 5
local : 4
direct : 2
am : 1

The leaf switch where the destination resides actually shows permits in the CLI for the contract

LEAF-105# show logging ip access-list internal packet-log permit | grep 192.168.209.148
[2023-05-18T16:23:36.003068000+01:00]: CName: PRODUCTION:PRODUCTION_VRF(VXLAN: 2359296), VlanType: FD_VLAN, Vlan-Id: 2, SMac: 0x84a938df8198, DMac:0x0022bdf819ff, SIP: 192.168.209.148, DIP: 10.131.161.38, SPort: 0, DPort: 0, Src Intf: Ethernet1/12, Proto: 1, PktLen: 74

 

The communication works so maybe I'm misunderstanding the output.

 

As I said, I am new to ACI so I'd be grateful for any help.

 

Thank you

Jon
