Configure DCB APP features

There is no direct way to configure the application priority feature. But the application priority map is always the same as the PFC priority map.

  1. Check the current application priority configuration.
    SEFOS# show interfaces extreme-ethernet 0/21 dcb application-etype-fcoe detail
    Port             :      Ex0/21
    Show Type        :      Admin Config
    Feature          :      Application FCoE
    Enable           :      true
    Advertise        :      true
    Priority Map     :     0      0      1      0      0      0      0      0
     
    Show Type        :      Oper Config

  2. Change the PFC priority map.
    SEFOS# configure terminal
    SEFOS(config)# interfaces extreme-ethernet 0/21
    SEFOS(config-if)# set dcb priority-flow-control vlan-priority 0 0 0 1 0 0 0 0
    SEFOS(config-if)# end
    SEFOS# show interfaces extreme-ethernet 0/21 dcb application-etype-fcoe detail
    Port             :      Ex0/21
    Show Type        :      Admin Config
    Feature          :      Application FCoE
    Enable           :      true

    Priority Map     :     0      0      0      1      0      0      0      0
     
    Show Type        :      Oper Config

    Priority Map     :     0      0      0      1      0      0      0      0
     
    Show Type        :      Peer Config

    Since the application priority is only informative, the configuration on both sides do not affect each other.
