Definition
Advertises the system's configured VTP management domain
name-string. Used by network operators to verify VTP domain
configuration in adjacent network nodes.
Indicates, per interface, the assumed VLAN for untagged packets on
the interface. CDP learns the native VLAN for an interface. This
feature is implemented only for interfaces that support the
IEEE 802.1Q protocol.
Indicates status (duplex configuration) of CDP broadcast interface.
Used by network operators to diagnose connectivity problems between
adjacent network elements.
Purpose
Enables CDP globally.
Enters interface configuration mode.
