Abstract
Abstract A network device with selectable traps that improves network management by enabling a system manager or administrator to select between multiple trap definitions. The network device includes a memory that stores a management database including a plurality of trap definitions and a programmable parameter for selecting any one of the trap definitions. The network device further includes management processing logic that executes a management agent that issues traps according a selected one of the trap definitions depending upon the programmable parameter. In the embodiment described herein, the management database includes the standard Ethernet TM Repeater MIB implemented according to RFC 1516 including a first trap definition and the Ethernet TM Hub MIB by Novell including a second trap definition. The management agent issues traps according to either one of the trap definitions depending upon the programmable parameter.

Claim 1
Independent Claim
66 words
A network device with selectable traps, comprising: a memory that stores a management database including a plurality of trap definitions and a programmable parameter for selecting any one of said plurality of trap definitions; and management processing logic coupled to said memory that executes a management agent that issues traps according to a selected one of said plurality of trap definitions depending upon said programmable parameter.
Claim 2
Dependent Claim
66 words
A network device with selectable traps, comprising: a memory that stores a management database including a plurality of trap definitions and a programmable parameter for selecting any one of said plurality of trap definitions; and management processing logic coupled to said memory that executes a management agent that issues traps according to a selected one of said plurality of trap definitions depending upon said programmable parameter.
Claim 3
Dependent Claim
58 words
The network device of claim 1, further comprising: said memory storing a first management database including a first set of trap definitions and a second management database including a second set of trap definitions; and said management processing logic issuing traps according to one of said first and second sets of trap definitions depending upon said programmable parameter.
Claim 4
Dependent Claim
25 words
The network device of claim 2, wherein said first and second management databases are both management information bases according to the simple network management protocol.
Claim 5
Dependent Claim
19 words

Claim 12
Dependent Claim
107 words
A network system, comprising: a network device with selectable traps, including: an interface; a management database including a first set of trap definitions, a second set of trap definitions and a programmable parameter for selecting between said first set of trap definitions and said second set of trap definitions; and management processing logic that executes a management agent that accesses said management database and that issues traps according to one of said first and second sets of trap definitions depending upon said programmable parameter; and a management unit coupled to said network device interface that programs said programmable parameter and that receives said traps via said interface.
Claim 13
Dependent Claim
107 words
A network system, comprising: a network device with selectable traps, including: an interface; a management database including a first set of trap definitions, a second set of trap definitions and a programmable parameter for selecting between said first set of trap definitions and said second set of trap definitions; and management processing logic that executes a management agent that accesses said management database and that issues traps according to one of said first and second sets of trap definitions depending upon said programmable parameter; and a management unit coupled to said network device interface that programs said programmable parameter and that receives said traps via said interface.
Claim 14
Dependent Claim
13 words
