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 management server.
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 Configure SNMP dialog box in the Element
Manager application, users at SNMP management workstations can
modify MIB variables. Switch modifications performed through
SNMP management work stations are recorded in the associated
Sphereon 4500 audit log and are available through the Element
Manager application. For additional information, refer to the
McDATA OPENconnectors SNMP Support Manual (620-000131).
