latest sampling interval
Display information about
discarded packets on an interface
Display summary information
about discarded packets on all
interfaces
Display the information about a
manual port group or all manual
port groups

loopback function

PFC configuration example

Network requirements
As shown in Figure
Switch A connects to the FCoE HBA of the DC server through Ten-GigabitEthernet 1/0/1, and
•
connects to Switch B through Ten-GigabitEthernet 1/0/2.
The 802.1p priority of FCoE packets is 3. Configure the switches to guarantee no packet loss for
•
FCoE packets forwarded among Switch B, Switch A, and DC server.
Suppose Switch A and Switch B support PFC, and Switch A and DC server support DCBX.
You should also configure DCBX on the port that connects Switch A to the FCoE HBA. This example
describes configuring DCBX to advertise the PFC data. For more information about the functions of DCBX,
see the chapter "LLDP configuration."
