Command

Purpose

 

 

 

 

Step 5 Router(config)# snmp-server enable

Enables the router to send SNMP traps messages. Use the no form of this

 

traps [notification-type]

command to disable SNMP notifications.

 

[notification-option]

• notification-type—snmp [authentication]—Enables RFC 1157

 

 

 

Example:

SNMP notifications. Note that use of the authentication keyword

 

produces the same effect as not using the authentication keyword.

 

Router(config)# snmp-server enable

 

Both the snmp-server enable traps snmp and snmp-server enable

 

traps snmp linkdown linkup

 

traps snmp authentication forms of this command globally enable

 

coldstart warmstart

 

(or, if using the no form, disable) the following SNMP traps:

 

 

 

 

–

authentication failure

 

 

–

linkup

 

 

–

linkdown

 

 

–

coldstart

 

 

–

warmstart

 

 

• notification-option—(Optional)atm pvc [interval seconds]

 

 

[fail-intervalseconds]—The optional interval seconds

 

 

keyword/argument combination specifies the minimum period

 

 

between successive traps, in the range from 1 to 3600. Generation of

 

 

PVC traps is dampened by the notification interval to prevent trap

 

 

storms. No traps are sent until the interval lapses. The default interval

 

 

is 30.

 

 

The optional fail-interval seconds keyword/argument combination

 

 

specifies the minimum period for storing the failed time stamp, in the

 

 

range from 0 to 3600. The default fail-interval is 0.

 

 

• envmon [voltage shutdown supply fan temperature]—When

 

 

the envmon keyword is used, you can enable a specific environmental

 

 

notification type, or accept all notification types from the

 

 

environmental monitor system. If no option is specified, all

 

 

environmental notifications are enabled. The option can be one or

 

 

more of the following keywords: voltage, shutdown, supply, fan,

 

 

and temperature.

 

 

• isdn [call-information isdn u-interface]—When the isdn keyword

 

 

is used, you can specify the call-informationkeyword to enable an

 

 

SNMP ISDN call information notification for the ISDN MIB

 

 

subsystem, or you can specify the isdnu-interfacekeyword to enable

 

 

an SNMP ISDN U interface notification for the ISDN U interface

 

 

MIB subsystem.

 

 

• repeater [health reset]—When the repeater keyword is used, you

 

 

can specify a repeater option. If no option is specified, all repeater

 

 

notifications are enabled. The option can be one or more of the

 

 

following keywords:

 

 

– health—Enables IETF Repeater Hub MIB (RFC 1516) health

 

 

 

notification.

 

 

– reset—Enables IETF Repeater Hub MIB (RFC 1516) reset

 

 

 

notification.
