What is EFM network when installing DCNM?

[Tim Johnson]

We are looking into installing DCNM7.2 and in the prerequisites it refers to requiring two port groups:  "The host machine is installed with ESXi and two port groups are created—one for EFM network and the other for DCNM Management network."

What is the EFM network?  I can't find any documentation for this.  I'm familiar with ethernet first mile in infrastructure, but haven't heard of it referenced in data centers.

Thank you.

Hi Tim

EFM = Enhanced Fabric Management

see http://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/7_1_x/installation/DCNM_Installation_Guide_7-1-x/installing_DCNM.html

Walter.

Step 15 Choose your network mapping for the networks created in the prerequisites.

The dcnm-mgmt network provides connectivity (SSH, SCP, HTTP, HTTPS) to the Cisco Prime DCNM Open Virtual Appliance. In the Destination Network column, associate the network mapping with the port group that corresponds to the subnet associated with the Cisco Prime DCNM management network.

a. Map the enhanced-fabric-mgmt network to the port group that connects to the management network of switches.

b. If you are deploying more than one OVA for HA functionality, the following criteria must be met:

– Both Open Virtual Appliances should have their management access (eth0) and enhanced fabric management (eth1) interfaces in the same subnet.

– Both Open Virtual Appliances should be deployed with the same administrative password. This is to ensure that both Open Virtual Appliances are duplicates of each other for application access.
