‐ The Link Cost is equal to the sum of all established/low metric (or currently active) circuits’
MAX rates in the tunnel.
‐ Fabrics connected through FCIP merge if the ports are configured as VE_Ports, and do not
merge if they are configured as VEX_Ports. If VE_Ports are used in a Fibre Channel
Routing Services backbone fabric configuration, then the backbone fabric merges, but the
EX_Port-attached edge fabrics do not merge. For more information, refer to the Fabric OS
Administrator's Guide.
• Up to three FC trunking groups:
‐ Trunk group 0: FC ports 0, 1
‐ Trunk group 1: FC ports 6, 7
‐ Trunk group 2: FC ports 2, 3, 4, 5, 8, 9, 10, 11
FCOE10-24 blade
The FCOE10-24 blade has 24 Fibre Channel over Ethernet (FCoE) ports that enable the transmission
of FC frames over an Ethernet network via encapsulation in standard Ethernet packets. This is enabled
by adherence to Converged Enhanced Ethernet (CEE) standards, a low latency, lossless Ethernet
standard. This does not require dedicated Ethernet lines, but rather can make use of existing Ethernet
infrastructure to reduce costs.
NOTE
This blade cannot be used in the same chassis with an FC8-48E, FC8-64, FC16-48, FC16-64 port
blades or any of the application blades (FA4-18, FR4-18i, FX8-24, FS8-18).
The FCOE10-24 blade supports only optical cabling and transceivers (SFP+).
There are no licensing requirements for functionality on this blade.
The FCOE10-24 blade provides the following hardware features:
• 24 FCoE ports operating at 10 Gbps
• 32 FC ports operating at 8 Gbps through the backplane
• Hot pluggable
• I
2 C Management interface through the backplane
• JTAG support
• Blade power and status LEDs
• Link status LEDs per port
The FCOE10-24 blade also provides the following functionality features:
• FCoE switching
• CEE switching
• Standard Ethernet encapsulation
• End of row deployment
NOTE
With the switch in online state, if all the FCOE ports are shutdown, offline diags will continue to run.
After this, the blade will be in inoperable state and you need to issue slotpoweroff and slotpoweron to
recover.
Refer to the Fabric OS Administrator's Guide for information on configuring these features.
