NOTE: You can congure the transmission of more than one TLV type at a time. You can only enable ETS recommend TLVs
(ets-reco) if you enable ETS conguration TLVs (ets-conf). To disable TLV transmission, use the no form of the
command; for example, no advertise DCBx-tlv pfc ets-reco.
The default is All TLV types are enabled.
5 Congure the Application Priority TLVs that advertise on uncongured interfaces with a manual port-role.
PROTOCOL LLDP mode
[no] advertise DCBx-appln-tlv {fcoe | iscsi}
• fcoe: enables the advertisement of FCoE in Application Priority TLVs.
• iscsi: enables the advertisement of iSCSI in Application Priority TLVs.
The default is 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
Fibre Channel over Ethernet and iSCSI Optimization.
6 Congure the FCoE priority advertised for the FCoE protocol in Application Priority TLVs.
PROTOCOL LLDP mode
[no] fcoe priority-bits priority-bitmap
The priority-bitmap range is from 1 to FF.
The default is 0x8.
7 Congure the iSCSI priority advertised for the iSCSI protocol in Application Priority TLVs.
PROTOCOL LLDP mode
[no] iscsi priority-bits priority-bitmap
The priority-bitmap range is from 1 to FF.
The default is 0x10.
DCBx Error Messages
The following syslog messages appear when an error in DCBx operation occurs.
LLDP_MULTIPLE_PEER_DETECTED: DCBx is operationally disabled after detecting more than one DCBx
peer on the port interface.
LLDP_PEER_AGE_OUT: DCBx is disabled as a result of LLDP timing out on a DCBx peer interface.
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
a compatible (match) or incompatible (mismatch) PFC configuration from a peer.
DSM_DCBx_ETS_PARAMETERS_MATCH and DSM_DCBx_ETS_PARAMETERS_MISMATCH: A local DCBx port received
a compatible (match) or incompatible (mismatch) ETS configuration from a peer.
LLDP_UNRECOGNISED_DCBx_TLV_RECEIVED: A local DCBx port received an unrecognized DCBx TLV from
a peer.
Debugging DCBx on an Interface
To enable DCBx debug traces for all or a specic control paths, use the following command.
