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

Description

Configures an application priority to be advertised to DCBX end stations.

Syntax Description

all

Specifies all ports on the switch.

port_list

Specifies one or more ports or slots and ports.

application_name

Specifies an application. Supported values are:

  • fcoe—Fiber Channel Over Ethernet (FCoE).

  • fip—FCoE Initiation Protocol (FIP).

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

ethertype_value

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.

priority_value

Specifies a priority in the range of 0 to 7.

Default

N/A.

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.

The switch supports a maximum of 8 DCBX applications per port. If an application configuration already exists on the specified port or ports, the priority is updated to the new value. If the maximum number of applications for a port is exceeded, the switch logs an error message.

Example

The following command configures the switch to advertise priority 4 for the iSCSI application on ports1 to 24:

configure lldp ports 1-24 dcbx add application name iscsi priority 4

The following command configures the switch to advertise priority 3 for ethertype value 34525 on port1:

configure lldp ports 1 dcbx add application ethertype 34525 priority 3

The following command configures the switch to advertise priority 6 for Layer 4 port 992 on port1:

configure lldp ports 1 dcbx add application L4-port 992 priority 6
