General Information
SNMP Trap Message
Support
Unsolicited SNMP trap messages that indicate switch operational
state changes or failure conditions can be customer-configured to be
transmitted to up to 12 management workstations. If installed on a
dedicated Ethernet LAN, the workstations communicate directly
with each switch. If installed on a customer intranet, the workstations
communicate with switches through the browser-capable PC.
SNMP data and trap messages are defined in the Fibre Channel
FE-MIB definition, a subset of the TCP/IP MIB-II definition (RFC
1157), and a custom, switch-specific MIB. Customers can install
these MIBs (in standard ASN.1 format) on any SNMP management
workstation.
Although SNMP trap messages are typically transmitted to customer
personnel only, the messages may be provided to service personnel as
initial notification of a switch problem or as information included in
the fault isolation process. Generic SNMP traps include:
• coldStart - reports that the SNMP agent is reinitializing due
to a switch reset.
• warmStart - reports that the SNMP agent is reinitializing due
to a switch reset or initial program load (IPL).
• authorizationFailure - reports attempted access by an
unauthorized SNMP manager. This trap is configurable
and is disabled by default.
Switch-specific SNMP traps specified in the custom MIB include
Fibre Channel port operational state changes and FRU operational
state changes.
If authorized through the SANpilot interface, users at SNMP
management workstations can modify MIB variables. For additional
information, refer to the McDATA OPENconnectors SNMP Support
Manual (620-000131).
Tools and Test Equipment
This section describes tools and test equipment that may be required
to install, test, service, and verify operation of the switch. These tools
are supplied with the switch or must be supplied by service
personnel.
