vWLC is setting at ESXi and it has a management interface 10.0.10.2/24-vlan10 and a dynamic interface 10.0.20.2/24-vlan20. The ESXi host trunk to a physical switch that has vlan10 with ip address 10.0.10.10/24 and vlan 20 with ip address 10.0.20.10/24
The vWLC 10.0.10.2 and switch 10.0.10.10 can ping each other via vlan10. The issue is vWLC can ping the switch 10.0.20.10, but the switch cannot ping vWLC 10.0.20.2, and vWLC even cannot ping itself 10.0.20.2. Is this bug issue or something else?
