Cisco ACI - Debugging Network Connectivity
2018-01-12
We run Cisco ACI on a large-ish platform hosting Openstack VM’s and a number of external network connections. Recently we encountered an issue where one of our internal teams reported that they had stopped seeing data from a specific external network. The traffic had just mysteriously dropped off one day. Unfortunately for us, there was little documentation on how this link was configured, and everyone who had originally set up the environment was long gone.
