B-Series and MDS-Series switches have different options to configure fabric security. Port type security refers to the ability to restrict a switch port to assume a particular function. For example, a switch port can be restricted to function only as an F_port or an E_port. Challenge Handshake Authentication Protocol (CHAP) authentication applies to iSCSI interfaces. Persistent port disable means that a port remains disabled across reboots. Secure Shell (SSH) is an encrypted command line program that is used in place of Telnet. Switch ACL, Trusted switches, and Fabric binding are all methods to ensure that only authorized switches can be connected in a fabric. Connectrix Fundamentals

The most basic way is by connecting a laptop computer to the serial console port and issuing CLI (Command-Line Interface) commands. The console port is normally used when performing basic switch setup, like configuring the management port when the switch is first installed. Once configured with an IP address, the management port on the switch is used for all management operations. An administrator can use Telnet or SSH to login to the switch from a remote management station and issue text-based CLI commands. Each switch vendor also provides a Graphical User Interface for management. For B-Series switches, the single switch management GUI is called Web Tools. For MDS-Series switches, the single switch management GUI is called Device manager. CLI commands are often used to script and automate switch administration. Experienced admins may prefer using CLI commands, but the GUI is often preferred by new admins because of its user friendliness. No license is required for CLI, Web Tools or Device manager. Each switch vendor also provides licensed software tools to manage and monitor switches on a fabric wide basis. Fabrics with B-Series switches may be managed with Connectrix Manager Converged Network Edition (CMCNE). Fabrics with MDS-Series switches may be managed with Data Center Network Manager - SAN (DCNM-SAN). A final option is to deploy a third-party management framework such as Tivoli. Such frameworks can use SNMP to monitor all fabric elements. Connectrix Fundamentals
