DSM_DCBX_PEER_VERSION_CONFLICT: A local port expected to receive the IEEE, CIN, or CEE version
in a DCBX TLV from a remote peer but received a different, conflicting DCBX version.
DSM_DCBX_PFC_PARAMETERS_MATCH and DSM_DCBX_PFC_PARAMETERS_MISMATCH: A local DCBX port received

5 Configure the Application Priority TLVs to be advertised
on unconfigured interfaces with a manual port-role,
where:
• fcoe enables the advertisement of FCoE in Application
Priority TLVs.
• iscsi enables the advertisement of iSCSI in
Application Priority TLVs.
Default: Application Priority TLVs are enabled and
advertise FCoE and iSCSI.
Note: To disable TLV transmission, use the no form of the
command; for example, no advertise dcbx-appln-tlv iscsi.
For information about how to use FCoE and iSCSI, refer
to FIP Snooping and iSCSI Optimization.
