Configuring CDP compatibility (available only on
the HPE 3100 v2 EI)
When the switch is directly connected to a Cisco device that supports only CDP rather than LLDP,
you can enable CDP compatibility to enable the switch to exchange information with the
directly-connected device.
With CDP compatibility enabled on the switch, the switch can use LLDP to receive and recognize the
CDP packets received from the directly-connected device and send CDP packets to the
directly-connected device. The packets that the switch sends to the neighboring CDP device carry
the fields in
