Changing from Native Fabric mode to Access Gateway mode 4 Changing from Native Fabric mode to Access Gateway mode Converting to Access Gateway (AG) mode allows you to use the module as a device management tool that transparently connects hosts to the fabric. Refer to the Brocade Access Gateway Administrator's Guide for information on changing from Native Fabric mode to AG mode. Access Gateway mode default port mapping The SAN I/O Module can contain 24 total ports. Of these, F_Ports are ports 1 through 16 and N_Ports are ports 0 and 17 through 23. In Access Gateway mode, the SAN I/O Module F_Ports are mapped to N_Ports. The following table lists the factory-default F_Port to N_Port mapping for Access Gateway mode. For more information on changing port mapping and managing ports in Access Gateway mode, refer to the Brocade Access Gateway Administrator's Guide. Table 6 shows Access Gateway mapping information. NOTE Automatic failover and automatic failback are enabled on all N_Ports.

It has a single IP address and appears as a separate entity to the Telnet protocol and the Simple Network Management Protocol (SNMP). When SNMP devices send SNMP messages to a management console running SAN management software, the information is stored in a Management Information Base (MIB). The SAN I/O Module Fabric OS supports the FibreAlliance Fibre Channel Management (FCMGMT) MIBs, allowing the provision of needed information to a SAN administrator. In addition, the Brocade Fabric Access Layer (API) and the Storage Management Initiative (SMI) provide facilities for the discovery and management of physical and logical elements in a SAN. Using the Fabric Access interface to the Fabric OS, a client application can retrieve information and modify the configuration of Brocade switches in the fabric. Secure Telnet access is available using Secure Shell (SSH), a network security protocol for secure remote login and other secure network services over an insecure network. Brocade Web Tools management is available through a secure browser using Secure Sockets Layer (SSL) and Transport Layer Security (TLS). The SSL/TLS security protocol provides data encryption, server authentication, message integrity, and optional client authentication for a TCP/IP connection. Because SSL/TLS is built into all major browsers and web servers, installing a digital certificate enables the SSL/TLS capabilities.
