This topic describes the CX220 FC switch module in terms of the functions, protocols, and ports.

The CX220 FC switch module (hereinafter referred to as CX220) is the storage switching unit that provides storage data switching for server blades and provides external service and management ports in a centralized manner.

The CX220s are installed in the rear slots of the E9000 chassis. Through the E9000 chassis midplane, the CX220s are connected to the compute nodes and management modules to implement storage and management data switching, providing high-speed data transmission for users.

Table 2-1 describes the functions of the CX220.

Table 2-1 FC switching plane function description



Fibre Channel (FC) switching

FC optical port

Supports 4G/8G/16G FC autonegotiation, full duplex.


  • Supports the FC switching mode (Native) and access gateway mode (that is, NPV mode). NPV is short for N-Port virtualization.
  • Supports free mapping to the internal fibre channel (FC) ports and external FC ports in NPV mode.
  • Supports network connection between E_Ports and Brocade FC switches in FC mode. A license is required for the function.


Supports N_Port ID virtualization (NPIV). A physical port supports access of multiple N_Port_IDs.

FC switching

Link aggregation

Supports FC port multi-link aggregation to expand the port bandwidth and provide redundancy.

  • Supports connection only to Brocade FC switches.
  • Requires a license.

Configuration and maintenance

Configuration and management modes

  • Supports configurations using command lines.
  • Supports the HTTPS-based Webtool (graphical user interface).
  • Simple Network Management Protocol version 1/3 (SNMPv1/v3).
  • Supports the FC Fabric Element management information base (MIB).

Connection mode

  • Ethernet connection (over SSH, SNMP, or the Web).
  • Serial over LAN (SOL) connection.

Version upgrade

Supports online upgrades for software. Services are not interrupted during an upgrade. The upgrade takes effect after the restart.


To ensure secure service application, periodically upgrade the switch module software version.

Network security

System security

  • Hierarchical rights management based on user levels, preventing unauthorized users from accessing switch modules.
  • Supports Secure Shell (SSH) and Secure Sockets Layer (SSL).
  • Supports Hypertext Transfer Protocol Secure (HTTPS).
  • Supports SNMPv1/v3.
  • Supports Remote Authentication Dial In User Service (RADIUS) for user logins.
