Managing Cisco FabricWare
The Cisco FabricWare software running on the MDS 9020 Switch offers Fibre Channel switching services that realize maximum performance. Cisco FabricWare provides networking features such as zoning, advanced security, nondisruptive software upgrades, diagnostics, a CLI with syntax resembling Cisco IOS, and standard interfaces for management applications.
This appendix contains the following sections:
•Fibre Channel Support
•Managing Cisco FabricWare with Fabric Manager
Fibre Channel Support
Cisco FabricWare supports autoconfigured Fibre Channel ports capable of up to 4-Gbps bandwidth. Cisco FabricWare supports the following port types:
See the "About Interface Modes" section on page 20-3.
Cisco FabricWare supports Fabric Shortest Path First (FSPF) as the standard path selection protocol used by Fibre Channel fabrics. The FSPF feature is enabled by default on all Fibre Channel switches. Except in configurations that require special consideration, you do not need to configure any FSPF services. FSPF automatically calculates the best path between any two switches in a fabric.
Zoning enables you to set up access control between storage devices or user groups. If you have administrator privileges in your fabric, you can create zones to increase network security and to prevent data loss or corruption. Zoning is enforced by examining the source-destination ID field. Cisco FabricWare does not support QoS, broadcast, LUN, or read-only zones.
You can use the Fabric Manager zone configuration tool to manage zone sets, zones, and zone membership for switches running Cisco FabricWare. Cisco FabricWare supports zone membership by pWWN. See the "Configuring a Zone Using the Zone Configuration Tool" section on page 30-12.
Cisco FabricWare supports the following security features:
•IP access control lists
Cisco FabricWare can use the RADIUS protocol to communicate with remote AAA servers. RADIUS is a distributed client/server protocol that secures networks against unauthorized access. In the Cisco implementation, RADIUS clients run on Cisco MDS 9000 Family switches and send authentication requests to a central RADIUS server that contains all user authentication and network service access information.
You can access the CLI using the console (serial connection), Telnet, or Secure Shell (SSH). For each management path (console or Telnet and SSH), you can configure one or more of the following security control options: local, remote (RADIUS), or none.
Using these access methods, you can configure the roles that each authenticated user receives when they access the switch. Cisco FabricWare supports two fixed roles: network administrator and network operator.
IP access lists (IP-ACLs) control management traffic over IP by regulating the traffic types that are allowed or denied to the switch. IP-ACLs can only be configured for the mgmt0 port.
Fabric Manager Server uses SNMPv1 and SNMPv2 to communicate with Cisco FabricWare.
You can monitor fabric and switch status for Cisco FabricWare switches through either a syslog server or an SNMP trap receiver.
The syslog, or system message logging software, saves messages in a log file or directs the messages to other devices. This feature provides you with the following capabilities:
•Provides logging information for monitoring and troubleshooting
•Allows you to select the types of captured logging information
•Allows you to select the destination server to forward the captured logging information
By default, the switch logs normal but significant system messages to a log file and sends these messages to the system console. You can specify which system messages should be saved based on the type of facility and the severity level. You can access logged system messages using the CLI or by saving them to a properly configured system message logging server.
You can configure the Cisco MDS 9020 Switch using the CLI to send notifications to SNMP managers when particular events occur. You can send these notifications as traps.
Managing Cisco FabricWare with Fabric Manager
Fabric Manager supports switches running Cisco FabricWare.
