Hi all, I have changed the topology to one way link, I'll study it if I have time.This project is over,thanks all. Regards

Hi AMD_Gamer, I have post my configuation,do you have find any problem on this?The vmotion get better than before,but HA testing one vm host failed.

Hi lopoetve, All of the hosts are configured with HA.HA testing was ok in one way situation.I can fell the vmotion get better than before after I have changed the port to portfast mode.The most important thing I cared is the HA switching. I want to konw if you have the same problem...

My topology: SW01+SW02: Vcenter live SW01--SW03 SW02--SW04 SW03+SW04: ESX04,ESX05 live Vlan 2: Vcenter,Service console Vlan 3: Vmkernel (Vmotion/HA) *************************************Begin********************************** XYUN-L3SW01# ! interface GigabitEthernet0/7 --->Vcenter...

And it's strange that at first three vm hosts failed to vmotion,but these can be success at second time.Why?Portfast problem? I can fell that the vmotion speed grows up when I change the port to portfast. I only change the ESX host port to portfast,not Vcenter host. I'll post the four...

Hi dear all, After I change the port to portfast which connect the EXS hosts,the vmotion success percent at 80%.And there are a vm host failed to swith HA,the other 4 vm hosts are ok.

Hi When I put the vcenter at switch B and disconnect the link between switch A&C,the success percent grows to 100%! But when I put vcenter at switch C and disconnect the link between switch A&C,the success percent fall to 57%! The vcenter gateway live in switch A. Does it relate...

Hi AMD Gamer, These are new switches.At first,I suspect it's a loop problem.But even I change the spanning-tree cost manually, the problem are still. But when I disconect the link between switch A and B, or switch A and C, it turn to better. So I think maybe it's the switch configuration...

Hi jenuster Remove your link between A & C and place VCenter machine in either B or C and see what happens. >>>>I'll test it after a while. Has this always been the case or did the issue just arise? I would try the recommendation from an earlier post: place all the NIC's into a...

I have find a title about "vSphere Host NIC Design - 10 NICs" The link as follow http://www.kendrickcoleman.com/index.php?/Tech-Blog/vsphere-host-nic-configuration-10-nics.html He used stack switch,that mean the vcenter and the esx server live in the same switch. And I have a test,I put the...

The other switch is: XYUN-L3SW03#sh sp vlan 2 VLAN0002 Spanning tree enabled protocol ieee Root ID Priority 20482 Address e804.62c0.2800 Cost 4 Port 8 (GigabitEthernet0/8) Hello Time 2 sec Max Age 20...

Hi NetJunkie, Thanks.I think there are no loop.The spanning-tree have blocked the link between switch A and switch C. Ping is ok always. The following is the information for "show spanning vlan 2": XYUN-L3SW04#sh sp vlan 2 VLAN0002 Spanning tree enabled protocol ieee Root ID...

Hi, I'm getting in trouble with vmotion at 10%.The success percent is about 67%.The environment is : One vcenter server,two ESX server with HA, three cisco 2960 switchs. Vcenter connected switch A, which connected switch B and switch C,all of these ports belong to vlan 2. There are two ESX...
