I have several supermicro servers (X8DTU-F, X7SPA-HF). I am using IPMI configuration with shared ethernet port (X7SPA-HF doesn't have dedicated port though). IPMI over ethernet is working perfectly. So servers network connectivity do.
The problem is that servers can't access to it's ipmi ip through shared port localy (it's working with dedicated). So, if I try to ping (also arping) from server to it's ipmi ip, it doesn't work.
Server and IP is on the same network and I can access to either server and ipmi without any issues. So the issue seems to be only somewhere in localswitch on SMC motherboard.
Any idea, where can be the issue?
Wesley's answer is accurate. Thanks for that. To workaround this problem - use separate networks for the server and ipmi. Set the access port on the switch to trunk and allow only vlan for the server itself (untagged) and vlan for ipmi (tagged). On IPMI then set up packet tagging with specific vlan id. This way all packets (even though they use the same interface) will go through the gateway and will not be delivered directly.
