FCoE/DCB/CEE (Brocade 8000 and FCOE10-24)
• When upgrading a Brocade 8000 or DCX/DCX-4S with one or more FCOE10-24 blades from FOS v6.x
to FOS v7.0.0 or later, the user should carefully review Chapter 5 of the FOS v7.0.0 Converged
Enhanced Ethernet Administrator’s Guide.
• FOS v7.0 or later supports a new optimized model for provisioning FCoE with fewer configuration steps
to enable FCoE on DCB ports. These changes do not allow the Brocade 8000 to retain FCoE
configuration information following an upgrade to FOS v7.0 or later. After the upgrade to FOS v7.0 or
later, all FCoE edge ports will need to be provisioned with the new model before any FIP FLOGIs will
take place
• Although including Brocade 8000 in the path of TI (Traffic Isolation) and ETI (Enhanced Traffic
Isolation) Zones is not prohibited, it is not supported. Configuring Brocade 8000 in the TI/ETI Zone
path is not recommended and will result in undefined behavior.
• Ethernet L2 traffic with xSTP Hello timer set to less than or equal to 3 seconds may experience
momentary traffic disruption during HA failover.
• The Brocade 8000 balances the FCoE bandwidth across all six port groups (each port group contains
four ports). To get optimum performance for FCoE traffic it is recommended that the user distribute
server CNA connections across these six port groups.
• Hot plugging a CP with firmware level less than FOS v6.3.0 into a DCX or DCX-4S with an active
FCOE10-24 blade will result in the new standby CP not coming up.
• When operating in Converged Mode, tagged traffic on the native VLAN of the switch interface is
processed normally. The host should be configured not to send VLAN tagged traffic on the switch’s
native VLAN.
• When operating in Converged Mode, tagged frames coming with a VLAN tag equal to the configured
native VLAN are dropped.
• The Converged Network Adapter (CNA) may lose connectivity to the Brocade 8000/FCOE10-24 if the
CNA interface is toggled repeatedly over time. This issue is related to the CNA and rebooting the CNA
restores connectivity.
• The Brocade 8000 and FCOE10-24 support only one CEE map on all interfaces connected to CNAs.
Additionally, CEE map is not recommended for use with non-FCoE traffic. QoS commands are
recommended for interfaces carrying non-FCoE traffic.
• Before upgrading to FOS v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later, if the CEE map “default” value
already exists, the same “default” value is preserved after upgrading to FOS
v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later. However, if the CEE map “default” is not configured before
upgrading to FOS v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later, then after upgrading to FOS
v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later, the following CEE map “default” will be created
automatically:
cee-map default
