| Description |
|
When a connected host changes its IP address or position, two different entries for the same MAC address appears into topology. After going back to the previous configuration, the two of them are still present and last-seen field is not properly updated. It could lead to confusion when tracking hosts mobility. Problem appeared with L2switch version 0.1.3-Helium-SR3 on a physical OpenFlow-managed network. |

This is likely because we don't group "addresses" observations into hosts in a sane way. We might want to provide a way to use an addresses comparator to group hosts or even (enhance if needed and) use the topology processing frameworks tools for the same general thing. |
