No mac address at all.įinally, I rebooted one of my R710 and mac address came back on switch port (and I were able to access iDRAC), but just for a while: now I am stuck at same point.Īnyone got same problem? Could be a NIC firmware issue? We didn't upgrade any firmware recently, by the way. Port Mode Encapsulation Status Native vlan Switch port appears in trunking mode: sw-3#sh interfaces trunk
Also, I noticed that my switches are not learning mac addresses: sw-3#sh mac address-table interface GigabitEthernet 0/4 Recently I noticed that I am unable to reach any iDRAC. ESXi management in VLAN 250 (access port)Įvery port attached to first ethernet on server is configured with: interface GigabitEthernet0/4 I configured Gigabit 1 for mixed purpose: I configured the DHCP server to block any requests from that MAC address. This MAC address is associated with a PC that has a static IP assigned to it, and the computer only has one network adapter.
I noticed a strange issue with few Dell PowerEdge servers. While running an IP scan on my network, I recently noticed that the same MAC address showed up twice - with two different IP addresses.
