Chapter X. FCoE PDU Offload Target

iv. Enabling DCBX:

switch(config)# interface ethernet 1/13

switch(config-if)# priority-flow-control mode auto

switch(config-if)# flowcontrol send off

switch(config-if)# flowcontrol receive off

switch(config-if)# lldp transmit

switch(config-if)# lldp receive

switch(config-if)# no shutdown

v. If you have not created a zone then make sure the default-zone permits the vsan created,

otherwise the initiator and the target on that particular vsan although FLOGI’d into the switch

will not talk to each other. To enable it, execute the below command.

switch(config)# zone default-zone permit vsan 2

3.2. Collecting port information

To create a SCST target configuration, enable the interfaces. Next, determine the WWPN of

target and initiator nodes using the following procedure. In case of FCF mode, wait for FLOGI to

complete before proceeding.

For initiator machines, the WWPN can be determined using the following command:

[root@host]# cat /sys/class/fc_host/host<host_number>/port_name

You can use cxgbtool to view both target and initiator WWPNs. The command requires an

adapter device file to be specified. After loading chfcoe driver, device files will be created for

each adapter in /dev/chfcoeX, where X is index of the adapter.

[root@host]# ls /dev/chfcoe*

/dev/chfcoe0

The following section is applicable when FCoE PDU Offload Target is configured in

FCF or VN2VN mode.
