I'm in the middle of a deployment and have a question.
We have a pair of Nexus 3548's acting as 10 G edge switch to our Nuntanix Clusters who are trunked up to a pair of Cisco 4500's
We have 4 nodes in the cluster with a total of 10 nics all 10 gig and assigned to the VDS in Vsphere. On the VDS we set the MTU to 9000
Is there a way to separate the CVM traffic from the management traffic?
I would like to keep the CVM traffic from going up to the 4500's however we needed to create an SVI on the 4500's so we could manage them.
I'm getting Jumbo frame errors on both the Nexus and the 4500's and when I set the MTU on the VDS back to 1500 the errors went away. My guess is the CVM traffic is what's causing the issues and I would prefre not to mess with the MTU settings on the 4500's.
What is best practice here? What are other doing?
