Refer to the exhibit.
The FCoE packets fail to be forwarded through the switch. What is the minimum MTU QoS requirement for the FCoE to work?
A. 9000 bytes
B. 2000 bytes
C. 2158 bytes
D. 2240 bytes
D. 2240 bytes
What is the minimum MTU QoS requirement for the FCoE to work?
I Think C : 2158
Fibre Channel and FCoE payload MTU is 2158 bytes across the switch. As a result, the rxbufsize for Fibre Channel interfaces is fixed at 2158 bytes. If the Cisco Nexus device receives an rxbufsize from a peer that is different than 2158 bytes, it will fail the exchange of link parameters (ELP) negotiation and not bring the link up.
