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.
Configuring DCBx
You can use the CLI to configure DCBx.
Beginning in Privileged EXEC mode, use the following commands to
configure DCBx.
Command
configure
lldp dcbx version {auto
| cin | cee | ieee}
lldp tlv-select dcbxp
[pfc | application-
priority]
Purpose
Enter global configuration mode.
Optionally configure the administrative version for the
DCBx protocol:
• auto—Automatically select the version based on the peer
response (default)
• cin—Force the mode to Cisco-Intel-Nuova. (DCBx 1.0)
• cee—Force the mode to CEE (DCBx 1.06)
• ieee—Force the mode to IEEE 802.1Qaz
Enable LLDP to send specific DCBx TLVs if LLDP is
enabled to transmit on the given interface. Entering the
command with no parameters enables transmission of all
TLVs.
• pfc—Transmit the PFC configuration TLV
• application-priority—Transmit the application priority
TLV
