Custom Application Support
The DCBX custom application support feature allows you to prioritize and manage traffic flow through the switch based on the application type. This feature allows you to configure DCBX handling of the following applications:
Fiber Channel Over Ethernet (FCoE)
Internet Small Computer System Interface (iSCSI)
Any application that can be defined by:
- Ethertype value
- Layer 4 port number
- TCP port number
- UDP port number
When you configure a custom application, you define a priority number that applies to traffic related to that application. DCBX advertises this priority to end stations in an application TLV. End stations that support this feature use the priority number for communications with the switch. The priority number maps to an 802.1p value, which determines which QoS profile in the switch manages the application traffic.
The software supports a maximum of eight application configurations.
