Disabling DCBX
If it is desired to disable DCBX, the network operator can use the following
commands to eliminate the transmission of DCBX TLVs in the LLDP frames
on an interface:
no lldp tlv-select dcbxp application-priority
no lldp tlv-select dcbxp congestion-notification
no lldp tlv-select dcbxp ets-config
no lldp tlv-select dcbxp ets-recommend
no lldp tlv-select dcbxp pfc
These commands eliminate only the DCBX TLVs from use by LLDP. They do
not otherwise affect any manually configured DCBX capabilities or the
normal operation of LLDP.
