Troubleshooting Device Manager
While Fabric Manager provides real-time views of your network fabric, Device Manager provides a
real-time graphic representation of a Cisco MDS 9000 Family switch chassis, including the installed
switching modules, the supervisor modules, the status of each port within each module, the power
supplies, and the fan assemblies.
Device Manager allows you to troubleshoot device-specific configuration issues by providing detailed
information for verification. It also allows you to perform switch-level configurations, including:
• Configure zones for multiple VSANs
• Manage ports, PortChannels, and trunking
• Manage SNMPv3 and CLI security access to switches
• Manage alarms, events, and notifications
• Save and copy configuration files and software images
• View hardware configurations, chassis, modules, port status, and statistics
Device Manager uses the SNMP user name/password combination to communicate with the switch. The
SNMP user name is automatically synchronized with the CLI user names configured. If you use the
administrator password recovery procedure, you must manually reset the administrative password on the
switch to resynchronize the SNMP and CLI user name and password. See the “Recovering the
Administrator Password” section on page 2-32.
