Level 4

Hello,

 

I have a Cisco BE6K with two cards (vmnic0 , vmnic1) .

I have installed cucm and  im and presence  and cisco Expressway C with vmnic0 .

I would like to install cisco Expressway E , with DUAL NIC (DMZ1 and DMZ 2) , but i have just one vmnic (vmnic1) , how can i do it ?

 

Could you help me please !

 

Best regards

Akram

Can’t you use VLANs in ESXi? Usually with virtualisation you would not use the actual interfaces as such, but VLANs that are defined to be present on the trunk from the connected switch port.

Thank you for your reply ,

So , i can use two vlan dmz 1 and dmz 2 passed over one vmnic1 , for achieved archerecture dual NIC on expressway E ?

Best regards 

Be6k comes with two Nic port, one way of doing is assigning one port for CUCM,CUC.Expressway that means the port will be in UC vlan. second port will be configured as DMZ vlan.

 

  •  Vm network is used for UC applications and this network use Be6k's first network port to connect with Cisco switch. and on Cisco switch port it's configured with UC vlan.
  • vm network 2 is used for Expressway second NIC which connect with DMZ vlan.

Below mentioned is the Expressway E network settings.

And Expressway configurations as mentioned below.

other way is using trunk configurations and do the switching in Vm switch(but I never tried it).

Thank you for your reply,

 

For your information i have alredy configured and installed : CUCM Publisher , IM and presence , Cisco Expressway C  on vmnic0.

all those servers on the same subnet : 10.212.3.0 

for the second vmnic 1 i would install Cisco Expressway E , on DMZ 1 and DMZ2 on vmnic1.

Subnet of DMZ1 and DMZ2:

DMZ1 : 192.168.60.0/24

DMZ2: 192.168.80.0/24

How can i passed boths DMZ1 and DMZ2 on one vmnic1 to achieved DUAL NIC on expressway E.

 

 

Best regards

 

in my case, expressway E Nic 1 and all UC applications are in UC vlan. Expressway- E  NIC 2 in DMZ zone. 

 

for your case, u need to try Trunk configuration with configuration in Vm switch. But I never tried it.

You would need to use vSwitches in ESXi defined for the host. Below is an example of how we have this setup on one of our UCS hosts.

Apart from these two vSwitches that carries the UC traffic there is also a switch that is used for ESXi management.

You will also need to define the networks on the ESXi hosts.

These comes from the trunks that is defined for the connection to the switch infrastructure in your DC. There is nothing special with these, it's just a normal defined trunk on the switch port(s) that connects the physical server to your data center network.

Thank you fory your reply and your rich informations.

 

I have created Two Vswitch DMZ , and DMZ2  and added vmnic1 in DMZ ,

 

but when i  would like to add vmnic1 on DMZ2 , it give me this message:

 

How can i resolve it

Two things.

  • I have quite limited knowledge in French.
  • My expertise does not include VMware. Recommend you to seek help with proper configuration.

You should get one or two vSwitches, name them vSwitch1 and 2 for simplicity. On these you tie each one to one of your physical interfaces, or just have one vSwitch tied to both the interfaces for redundancy and speed bundling. On the interface(s) you carry across the information about VLANs from your switching environment via a switch port trunk to the VMware host. In VMware you need to define the VLANs and tie these to your vSwitch(s). See my other post with details on how you do that in VMware.

You cannot add same Nic in two vm switch. AFAIK you need to do trunk configuration on Cisco switport and play with vlan on Vmware. I never tried this configuration. you may need to seek help from VMware experts.

Have a look at this document for how setup of VLANs works in VMware. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.networking.doc/GUID-7225A28C-DAAB-4E90-AE8C-795A755FBE27.html
I assume you know how to configure a switch port to be a trunk? If not there are plenty of documentation for this on cisco.com.
