Hi 65td<br />
Thank you so much for info. But my Problem is Trunk ,if i Connect to vmnic physical TRK1 port then loose all Connection till i plug out it.
</div>


<div>
i did one test. I plugged only one VMNIC0 to HP Switch Trunk port 24. and plugged out ISCSI NAS machine from ESXI host and created Test Linux vm on the LOCAL DATA STORE.<br />
<br />
ist the same Problem ,if i plug the second NIC to HP SW port 23 ,then NO Connection again.
</div>


<div>
On switch side LAG is configured, what about other side (vmnic0,vmnic1,vmnic2)?<br />
Generally, it is recommended to configure LACP LAG on both sides.
</div>


<div>
i did not know ,if i Connect to esxi over TRUNK port NEEDS LACP enabled?
</div>


<div>
If one side is bundled in LAG other side must be too. LACP is industry standard to create LAG.
</div>


<div>
ok Thank you ,i will test today

ESXI 6.0 HP switch Trunk problem

The Dynamic Host Configuration Protocol (DHCP) is an auto configuration protocol used on IP networks and an extension of the Bootstrap Protocol. DHCP allows for computers to be configured automatically to communicate with each other over an IP network without the need for manual setup by a network administrator. The implementation of DHCP relies on a DHCP server to hand out network configuration information to DHCP-capable clients that request an IP address (and other information required or useful in communicating with other devices on an IP network). In addition to an IP address, common configuration information served over DHCP includes a default gateway, subnet mask and DNS sever(s).

DHCP

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
