An engineer is implementing FCoE.
Which aspect of DCBXP on a Cisco Nexus switch affects this implementation?

A. It requires that LLDP transmit and LLDP receive are enabled on the FCoE interface.

B. It uses the Cisco Fabric Services protocol to exchange parameters between two peer links.

C. It provides the authentication of peers on the Cisco Nexus switch.

D. It always is enabled on 10/100-Mbps native Ethernet ports.








 

Suggested Answer: A

The Data Center Bridging Exchange Protocol (DCBXP) is an extension of LLDP. It is used to announce, exchange, and negotiate node parameters between peers. DCBXP parameters are packaged into a specific DCBXP TLV. This TLV is designed to provide an acknowledgement to the received LLDP packet.
DCBXP is enabled by default, provided LLDP is enabled. DCBXP is disabled on ports where LLDP transmit or receive is disabled.
