ENABLE INTERFACE LINKTRAP
Syntax
enable interface= port linktrap
Parameter
port Specifies the port on which you want to enable SNMP
link traps. You can specify more than one port at a time.
You can specify the ports individually (for example,
5,7,22), as a range (for example, 18-23), or both (for
example, 1,5,14-22).
Description
This command activates SNMP link traps on the port. When enabled, the
switch sends an SNMP link trap to an SNMP trap receiver whenever there
is a change to the status of a link on a port.
Note
In order for the switch to send SNMP traps, you must activate SNMP
on the unit and specify one or more trap receivers.
Example
The following command enables link traps on port 21:
enable interface=21 linktrap
