Dell Networking S5000: Deployment of a Converged Infrastructure with FCoE
Configuration steps:
1. Create the LACP LAG up to the VLT
2. Configure port to CNA as hybrid port. Create a LAN VLAN and tag it to both the
'tengigabitethernet 0/12' interface going to the respective CNA and port channel going up to
VLT.
3. Enable FC capability
4. Create DCB Map and configure the priority-based flow control (PFC) and enhanced traffic
selection (ETS) settings for LAN and SAN traffic.
Priorities are mapped to priority groups using the 'priority-pgid' command. In this example,
priorities 0, 1, 2, 4, 5, 6, and 7 are mapped to priority group 0. Priority 3 is mapped to priority-
group 1.
5. Create FCoE VLAN
6. Next, create a FCoE MAP so FCoE traffic is mapped to the respective VLAN. The FCoE MAP is
applied to both the 'tengigabitethernet 0/12' interface going to the respective CNA port and to
the FC interface connecting to the FC switch. Note, on S5000, FCoE is always mapped to
priority 3.
7. Apply DCB map to downstream interface going to server.
The same procedure is repeated for the S5000 connecting to fabric B. Note that we used a different
'fc-map' and FCoE VLAN. Since fabric A and fabric B are isolated from each other, this was not
necessary, however, it may be easier to troubleshoot and understand if some distinction is made
between the two fabrics.
Especially important to note is the fact that the same Ethernet port on the S5000 where the FCoE
MAP is applied is also untagged on the default VLAN. This is needed because the FIP protocol
communicates over the default VLAN to discover the FCoE VLAN. The LAN traffic is tagged on VLAN
5.
