configure lldp ports [all | port_list] dcbx delete application [all-applications | name application_name | ethertype ethertype_value | L4-port port_number | tcp-port port_number | udp-port port_number]


Removes the priority configuration for one or all applications from the specified ports.

Syntax Description


Specifies all ports on the switch.


Specifies one or more ports or slots and ports.


Specifies an application. Supported values are:

  • fcoe—Fiber Channel Over Ethernet (FCoE).

  • fip—FCoE Initiation Protocol (FIP).

  • iscsi—Internet Small Computer System Interface (iSCSI).


Specifies an ethertype value in the range of 1536 to 65535.

L4-port port_number

Specifies a Layer 4 port number in the range of 0 to 65535. Supported Layer4 protocols include TCP, SCTP, UDP, and DCCP.

tcp-port port_number

Specifies a TCP port number in the range of 0 to 65535.

udp-port port_number

Specifies a UDP port number in the range of 0 to 65535.



Usage Guidelines

This command configures the switch to advertise the priority that an end station should use for the specified application or port number. The priority number is mapped to an 802.1p value, which determines how the switch manages traffic from that application or port.

If an application configuration already exists on the specified port or ports, the priority is updated to the new value.


The following command removes the priority configuration for Layer 4 port 30 on port 23:

configure lldp ports 23 dcbx delete application L4-port 30
