Configuring the DCBX version
When you configure the DCBX version, follow these restrictions and guidelines:
For DCBX to work correctly, configure the same DCBX version on the local port and peer port. As a best practice, configure the highest version supported on both ends. IEEE Std 802.1Qaz-2011, DCBX Rev 1.01, and DCBX Rev 1.00 are in descending order.
After the configuration, LLDP frames sent by the local port carry information about the configured DCBX version. The local port and peer port do not negotiate the DCBX version.
If the DCBX version is autonegotiated, the version IEEE Std 802.1Qaz-2011 is preferably negotiated.
To configure the DCBX version:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter Layer 2 Ethernet interface view. | interface interface-type interface-number | N/A |
3. Configure the DCBX version. | dcbx version { rev100 | rev101 | standard } | By default, the DCBX version is not configured. It is autonegotiated by the local port and peer port. |
