Connectivity Guide
long time to identify the issue and to recover from it. At times, interface apping occurs and might require manual intervention to recover.
To recover automatically, FSB sends a Clear Virtual Link (CVL) frame from the FCF to the ENode.
Conguration notes
• If you congure FSB with port pinning on the uplink or downlink side, you must congure the FCF-facing interface as FCF port mode.
• OS10 currently does not support a topology where a single port must be congured as both an ENode and an FCF-related port mode.
• If you congure FCF-transit port mode on an FSB, Dell EMC recommends not directly connecting ENodes on it.
Congure multi-hop FSB
The following example shows a simple multi-hop FSB setup. CNA-2 and CNA-3 shown in this topology are for illustrative purposes only. The
following example does not include CNA-2 and CNA-3 congurations.
Ensure that the access and core FSB switches are running in FSB mode.
To congure multi-hop FSB:
1 Congure the L2 switch.
a Disable ow control on the interfaces connected to CNA-4 and FSB1.
L2switch(config)# interface ethernet 1/1/32
L2switch(conf-if-eth1/1/32)# no flowcontrol receive
L2switch(conf-if-eth1/1/32)# no flowcontrol transmit
L2switch(config)# interface ethernet 1/1/5
L2switch(conf-if-eth1/1/5)# no flowcontrol receive
L2switch(conf-if-eth1/1/5)# no flowcontrol transmit
b Enable DCBX.
L2switch(config)# dcbx enable
c Create a VLAN for FCoE trac to pass through.
L2switch(config)# interface vlan 777
