Deployment Guide

Reason Description
LLDP Rx/Tx is
disabled
LLDP is disabled (Admin Mode set to rx or tx only) globally or on the interface.
Waiting for Peer Waiting for peer or detected peer connection has aged out.
Multiple Peer
Detected
Multiple peer connections detected on the interface.
Version Conict DCBx version on peer version is dierent than the local or globally congured DCBx version.
Cong-source Down Although DCBx parameters match in auto-upstream or auto-downstream port, the conguration source (elected
dynamically or CLI-congured) is down.
Unrecognized TLV
received
Invalid TLV length TLV has been received. In the case of an invalid PFC or ETS TLV, the error displays in the show
interfaces pfc | ets output. The show interfaces dcbx output displays PFC or ETS as down.
Admin Mode OFF
(Local)
Local Admin Mode is disabled.
Admin Mode OFF
(Remote)
Remote Admin Mode is disabled.
Waiting for ACK
from Peer
For a legacy DCBx version, a peer has not acknowledged the reception of a sent packet. This reason displays only
when a remote peer is willing to receive a DCB conguration.
Error Bit set For a legacy DCBx version, a peer has sent packets with an error bit set. This reason displays only when a remote
peer is willing to receive a DCB conguration.
Enabled with ETS
Mismatch (show
interfaces
dcbx output)
DCBx is enabled but an ETS validation failure error has occurred.
PFC is down (show
interfaces pfc
output)
One of the following PFC-specic errors has occurred:
• No MBC support.
• Congured PFC priorities exceed maximum PFC capability limit.
• New dot1p-to-queue mapping violates the allowed system limit for PFC Enable status per priority
ETS is down (show
interfaces ets
output)
One of the following ETS-specic errors occurred in ETS validation:
• Unsupported PGID
• A priority group exceeds the maximum number of supported priorities.
• COSQ is mapped to more than one priority group.
• COSQ is mapped to more than one priority group. - Invalid or unsupported transmission selection algorithm
(TSA).
• Bandwidth is congured for an uncongured priority group.
• Total ETS bandwidth mapped in priority groups is not equal to 100%.
• Priorities mapped to a queue use dierent TSAs.
• Total bandwidth assigned to priorities in one or more priority groups is not equal to 100%.
Or one of the following ETS failure errors occurred:
• Incompatible priority group ID (PGID).
• Incompatible bandwidth (BW) allocation.
• Incompatible TSA.
• Incompatible TC BW.
