Support for Cisco Discovery Protocol (CDPv1) was added in ExtremeXOS 15.4. This update to the feature adds support for Cisco Discovery Protocol (CDPv2). CDPv2 is a proprietary protocol designed by Cisco to help administrators collect information about nearby, and directly connected, devices. Support for listening, lifting, processing, and periodic transmitting of the CDPv1/v2 control packets on a per-port basis is implemented in this current release.
Changes are underlined.
