Configure DCB Features

The following example shows the default configuration values for all three DCB features. Perform the following task to apply the default DCB configuration, enabling all three of the DCB features.

See Default Settings for detailed information about the specifications used in the following example. See other sections in this document for additional details on each command.

  1. Start DCB globally.
    SEFOS# configure terminal
    SEFOS(config)# no shutdown dcb
  2. Enable DCB features on interface 0/2 and start the interface.
    SEFOS(config)# interface extreme-ethernet 0/2
    SEFOS(config-if)# set dcb enable
    SEFOS(config-if)# set dcb priority-flow-control enable
    SEFOS(config-if)# set dcb priority-flow-control vlan-priority 0 0 0 1 0 0 0 0
    SEFOS(config-if)# set dcb priority-flow-control mode auto
    SEFOS(config-if)# set dcb priority-group enable
    SEFOS(config-if)# set dcb priority-group 0 0 0 1 2 2 2 15 bandwidth 50 30 20 0 0 0 0 0
    SEFOS(config-if)# set dcb priority-group mode auto
    SEFOS(config-if)# set dcb application-etype-fcoe enable
    SEFOS(config-if)# lldp tlv-select dcb1tlv priority-group priority-flow-control applicationetype-fcoe
    SEFOS(config-if)# no shutdown
    SEFOS(config-if)# exit
  3. Enable DCB features on interface 0/18 and start the interface.
    SEFOS(config)# interface extreme-ethernet 0/18
    SEFOS(config-if)# set dcb enable
    SEFOS(config-if)# set dcb priority-flow-control enable
    SEFOS(config-if)# set dcb priority-flow-control vlan-priority 0 0 0 1 0 0 0 0
    SEFOS(config-if)# set dcb priority-flow-control mode auto
    SEFOS(config-if)# set dcb priority-group enable
    SEFOS(config-if)# set dcb priority-group 0 0 0 1 2 2 2 15 bandwidth 50 30 20 0 0 0 0 0
    SEFOS(config-if)# set dcb priority-group mode auto
    SEFOS(config-if)# set dcb application-etype-fcoe enable
    SEFOS(config-if)# lldp tlv-select dcb1tlv priority-group priority-flow-control applicationetype-fcoe
    SEFOS(config-if)# no shutdown
    SEFOS(config-if)# end
  4. Assign VLAN 201 to ports 2 and 18 for traffic pass-through and isolation.
    SEFOS# configure terminal
    SEFOS(config)# vlan 201
    SEFOS(config-vlan)# ports add extreme-ethernet 0/2,0/18
    SEFOS(config-vlan)# exit
  5. Start LLDP globally.

    LLDP must be started and enabled for DCBX protocol TLVs exchange.

    SEFOS(config)# no shutdown lldp
    SEFOS(config)# set lldp enable
    SEFOS# end
