Hi, I have a test VMM domain setup where I can't ping the gateway from any VM attached to an EPG tied to a VMware VMM domain. Both the vpc leafs pair and the ESXi hosts (UCS-B) can see the FIs via CDP:
Leaf201# show cdp neighbors | begin UCS
UCS-6120-A
Eth1/47 135 S I s N10-S6100 Eth1/1
UCS-6120-B
Eth1/48 138 S I s N10-S6100 Eth1/1
I noticed that neither the BD or EPG information is getting programmed, please see the show vlan output:
Leaf201# show vlan VLAN Name Status Ports ---- -------------------------------- --------- ------------------------------- 13 infra:default active Eth1/1, Eth1/2, Eth1/3 45 XXX_tenant1:test_app_bd active VLAN Type Vlan-mode ---- ----- ---------- 13 enet CE 45 enet CE Remote SPAN VLANs -------------------------------------------------------------------------------
The vswitch policy is configured with LLDP off, CDP on and MAC-Pining:
To test that all the vlans are correctly trunked (DVS -- FI -- Leaf) when I change the EPG VMM domain resolution immediacy to Pre-proviosioning I can reach the ACI gateway.
Could you please point what could be missing?
When using pre-provision immediacy, policy is downloaded to ACI leaf switch regardless of CDP/LLDP neighborship, even without a hypervisor host connected to the VMM switch. This could be related to ACI not detecting the CDP/LLDP adjacency and not building the loose node relationship correctly and in turn not pulling inventory correctly from the ESXI host in question. If you go to Fabric -> Inventory -> Unmanaged Fabric Nodes -> Find the FIs -> does the blade switch see the ESXI hosts?
