Hi all
I would like some advice about the best pratices to define a VPC with multiple ESXi, vlan and on 2 Datacenters my architecture is 4 leafs (2 on each DCs) leaf 1,2 then 3 and 412 ESXi (6 on each DCs)For each Esxi I have 4 10G splitted in 2 Por...
Hi all,I have an UCS architecture from ESxi to N5K (with MK81R and FI6248)I would like to check a ping or wmkping between 2 hosts with failure.So I started to check the jumbo frame between 2 N5K on the same vlan and I have the same...
Hi , I have a full redundant architecture based on Exsi, (VDS or N1K), UCS and N5K (L2 and L3) in VPC configuration. it works but I am not sure of my configuration , perhaprs I read too many things.When I create a NLB in Multicast mode, do I only cr...
Hi ,I changed some Vmnics on UCS 6248 (remove and create new one) but on 1000V I have an error 2012 Nov 13 11:29:17 E2VSM001 %ETH_PORT_CHANNEL-5-PCM_ROLLBACK_MAX_PORTS_EXCEEDED: Max ports per channel exceeded while trying to create port-channel 0. Ro...
Hi ,I am using a Nexus 1000v a FI 6248 with a Nexus 5K in redundant architecture and I have a strange bevahior with VMs.I am using port-profiles without any problems but in one case I have this issue I have 2 VMs assigned to the same port profileWhe...
Hi all,I found the solution, what I understand is that the service policy works at level 2 and if you want to do it at L3 we must configure a mtu at 9216 on each interfaces vlans.I now I can ping both nexus 5K , together and from a device connected o...
Hi,I know that the MTU value to fix are9000 for exsi, N1K9216 for FI and UCSThe performance are very good with a mtu at 1500 (in fact I let the default value) and the vmotion works well, but at 9000 or 9216, the vmotion failed.It's why on the nexus ...
Hi ,thanks for your replySome comments VMs are in the same vlan and subnetVMs on the same host can reach each overOn FI I created 4 pairs of vmnics , one pair for path A and B (HA purpose) and the reason is to use differents FI QOS policy.The issue ...
No , I am still working with the Cisco support but they didn't find any problem of the configuration all seem correclty configured.the next step are to 1 - Delete all vlans and vmnic impacted by the problem and to recreate. 2 - perform a ...
Hi ,In fact the problem was link to the vmnic configuration on vsphere.The configuration on UCS and N1K were OK , Vsphere were not properly updated on the physical adapter tab. We checked the configuration and now all are OK, but we lost a lot of tim...
