Protocol-Mode

(QFX Series) DCBX protocol mode the interface uses:

  • IEEE DCBX Version—The interface uses IEEE DCBX mode.

  • DCBX Version 1.01—The interface uses DCBX version 1.01.

Note:

On interfaces that use the IEEE DCBX mode, the show dcbx neighbors interface interface-name operational command does not include application, PFC, or ETS operational state in the output.

Protocol-State

(DCBX Version 1.01 only) DCBX protocol state synchronization status:

  • in-sync—The local interface received an acknowledge message from the peer to indicate that the peer received a state change message sent by the local interface.

  • ack-pending—The local interface has not yet received an acknowledge message from the peer to indicate that the peer received a state change message sent by the local interface.

(DCBX Version 1.01 only)

Status of advertisements that the local interface sends to the peer.

Operational version

Version of the DCBX standard used.

sequence-number

Number of state change messages sent to the peer.

If the interface Protocol-State value is in-sync, this number should match the acknowledge-id number in the Peer-Advertisement section.

If the interface Protocol-State value is ack-pending, this number does not match the acknowledge-id number in the Peer-Advertisement section.

acknowledge-id

Number of acknowledge messages received from the peer.

If the Protocol-State value is in-sync, this number should match the sequence-number value in the Peer-Advertisement section.

If the Protocol-State value is ack-pending, this number does not match the sequence-number value in the Peer-Advertisement section.

Peer-Advertisement

 

(DCBX Version 1.01 only)

Status of advertisements that the peer sends to the local interface.

Operational version

Version of the DCBX standard used.

sequence-number

Number of state change messages the peer sent to the local interface.

If this number matches the acknowledge-id number in the Local-Advertisement field, this indicates that the local interface has acknowledged all of the peer’s state change messages and is synchronized.

If this number does not match the acknowledge-id number in the Local-Advertisement field, this indicates that the peer has not yet received an acknowledgment for a state change message from the local interface.

acknowledge-id

Number of acknowledge messages the peer has received from the local interface.

If this number matches the sequence-number value in the Local-Advertisement field, this indicates that the peer has acknowledged all of the local interface’s state change messages and is in synchronization.

If this number does not match the sequence-number value in the Local-Advertisement field, this indicates that the peer has not yet sent an acknowledgment for a state change message from the local interface.

(DCBX Version 1.01 only)

State that the peer advertises to the local interface:

  • Yes—The feature is enabled.

Priority-Group

CoS priority group (forwarding class set) identification number.

Percentage B/W

Configured minimum percentage of link bandwidth allocated to the priority group. (EX Series switches allocate 100% of link bandwidth to the default priority group, group 7.)

Transmission Selection Algorithm

(IEEE DCBX only)

Transmission selection algorithm used by the interface. The QFX Series supports ETS but does not support using the credit-based shaper algorithm, so the only value shown in this field is ETS.

PFC

(QFX Series, terse option only) DCBX TLV advertisement state for PFC:

  • Disabled—PFC configuration matches the configuration on the connected peer and PFC is disabled

  • Enabled—PFC configuration matches the configuration on the connected peer and PFC is enabled

  • Not Advt—Interface does not advertise PFC to the connected peer

ETS

(terse option only) Local DCBX TLV advertisement state for ETS:

  • Not Advt—Peer interface does not advertise ETS

Note:

When the DCBX mode is DCBX version 1.01, no peer information is displayed.

Version

(terse option only) The DCBX version used on the interface and whether the DCBX version was autonegotiated or explicitly configured:

  • IEEE—The interface uses IEEE DCBX.

  • 1.01—The interface uses DCBX version 1.01.

When the DCBX version used is the result of autonegotiation, the term (Auto) appears next to the version. For example, IEEE (Auto) indicates that the interface autonegotiated with the connected peer to use IEEE DCBX. Autonegotiation is enabled by default.
