How to tell new created vLAN to use new created Uplink Port Channel

Nevy

Good morning,

 

we have some UCS Domains administered by UCS Central2.0(1c). We have configured 2 new additional Uplink Ports and created in each FI a new Port Channel (nr 2). After that we have created new vLAN. My question is for my understanding or how to configure the next steps: How can should I configure the new vLAN / vNIC to take traffic through the new created Channel Port?e.g.If I assign to Service Profile Template the new vNIC template (with new created vLAN) the Server will have additional NIC for a new Network. The NIC or vNIC Or VLAN shoul be combined with the new created Port Channel, or shouldn't be? May be I have less knowledge about Routing or how is the Networking process in UCS .

 

Thanks in advance.

 

Best regards

Nevzat

You want to setup a Disjoint L2 Network.

We have a number of these already. We never used the Pin Groups. We just did Step 5 on Page 5 after you have the separate Portchannels setup.

Hi Robert,

Thank You for your answer. That is what I'm looking for. On page 1 under Note "..By default, data traffic in Cisco UCS works on a principle of mutual inclusion. All traffic for all VLANs and upstream networks travels along all uplink ports and port channels. If you have upgraded from a
release that does not support upstream disjoint layer-2 networks, you must assign the appropriate uplink
interfaces to your VLANs, or traffic for those VLANs continues to flow along all uplink ports and port
channels..." That means, usually I needn't to configure somesthing additional as all traffic travels along all port channels...Our first release was 3.x, I think it supports upstream disjoint layer-2 Networks.

So all VLANS will be using both Port Channels? If so, I believe by default everything will use the first port channel. If not, you will need to assign VLANs to the desired port channel. That is on Page 7 of the link I sent you.
