Fibre Channel ports on the HP B-series FCoE CN switches and HP C-series CN switches can be
used for ISL connections to an existing Fibre Channel fabric, or to an HP Fibre Channel storage
system or HBA.
Table 9 (page 64) lists the number of ports for each HP FCoE CN switch.

NOTE: All FCoE CN switch models are by design CEE/IEEE DCB switches and are enabled for
Ethernet by default. In order to be used for FCoE they must be enabled to forward FC frames to
the FC ports, functioning as a Fibre channel forwarder.
The FCoE CN switch firmware update process causes momentary loss of Ethernet and Fibre Channel
port connectivity. HP recommends that you implement a dual path configuration with redundant
FCoE CN switches to minimize disruption during firmware updates.
CN Switch Interoperability
The HP FlexFabric 5900CP Switch and HP 5820 Converged Network Switch interoperate with
B-series, C-series, or H-series FC switches using NPV/NPIV uplinks.
HP does not support E_Port interoperability between HP FlexFabric 5900CP, B-series, and C-series
CN and FC switches:
• 2408 FCoE Converged Network Switch and the 10/24 FCoE Blade operate with B-series FC
switches only.
• C-series Nexus 5010/5020 and Cisco Nexus 5548UP/5596UP Converged Network Switches
operate with other C-series MDS FC switches only.
