User Guidelines
NOTE: This command is only available on N40xx series switches.
In auto mode, the switch will attempt to jump start the exchange by sending
an IEEE frame, followed by a CEE frame followed by a CIN frame. The
switch will parse the received response and immediately switch to the peer
version. Because LLDP is a link local protocol, it cannot be configured on a
port channel or VLAN interface. It is recommended that all ports configured
in a port channel utilize the same LLDP configuration.
Example
The following example configures the switch to use CEE DCBX.
s1(config)#lldp dcbx version cee
lldp dcbx port-role
Use the lldp dcbx port-role command in Interface Configuration mode to
configure the port role to manual, auto-upstream, auto-downstream and
configuration source. The default port role is manual.
